823a633eeb media: field-order.rst: clarify FIELD_ANY and FIELD_NONE
Rephrased the FIELD_ANY description: rather than explicitly list
field values, just say 'when any field format is acceptable'. The
list of FIELD values was outdated, so it was a bit confusing.

The FIELD_NONE description said that 'The driver may also indicate
this order when it cannot distinguish between V4L2_FIELD_TOP and
V4L2_FIELD_BOTTOM'. This is false, NONE really means a full frame
and userspace depends on that. So drop this line completely. There
are no drivers that do this anyway.

FIELD_TOP/BOTTOM/ALTERNATE indicate that the number of lines in the
buffer are that of a field, not frame, so returning NONE here would
cause huge problems.

Finally attempt to clarify 'progressive' and 'interlaced' a little
bit.

468dfca38b dm integrity: add a bitmap mode
Introduce an alternate mode of operation where dm-integrity uses a
bitmap instead of a journal. If a bit in the bitmap is 1, the
corresponding region's data and integrity tags are not synchronized - if
the machine crashes, the unsynchronized regions will be recalculated.
The bitmap mode is faster than the journal mode, because we don't have
to write the data twice, but it is also less reliable, because if data
corruption happens when the machine crashes, it may not be detected.

Benchmark results for an SSD connected to a SATA300 port, when doing
large linear writes with dd:

buffered I/O:
        raw device throughput - 245MB/s
        dm-integrity with journaling - 120MB/s
        dm-integrity with bitmap - 238MB/s

direct I/O with 1MB block size:
        raw device throughput - 248MB/s
        dm-integrity with journaling - 123MB/s
        dm-integrity with bitmap - 223MB/s

For more info see dm-integrity in Documentation/device-mapper/

 It's really pretty small, not much happening in this portion of the
 kernel at the moment.  When the "highlight" is the movement of the
 documentation from .txt to .rst files, it's a good merge window.
 
 There's a number of small fixes and updates over the various serial
 drivers, and a new "tty null" driver for those embedded systems that
 like to make things even smaller and not break things.
 
 All of these have been in linux-next for a while with no reported

In addition, convert the table of possible values and their descriptions

far too wide in comparison to the second column that contained the

e672f8bf71 x86/mds: Add MDSUM variant to the MDS documentation
Updated the documentation for a new CVE-2019-11091 Microarchitectural Data
Sampling Uncacheable Memory (MDSUM) which is a variant of
Microarchitectural Data Sampling (MDS). MDS is a family of side channel
attacks on internal buffers in Intel CPUs.

MDSUM is a special case of MSBDS, MFBDS and MLPDS. An uncacheable load from
memory that takes a fault or assist can leave data in a microarchitectural
structure that may later be observed using one of the same methods used by
MSBDS, MFBDS or MLPDS. There are no new code changes expected for MDSUM.
The existing mitigation for MDS applies to MDSUM as well.

89e33ea732 docs: livepatch: convert docs to ReST and rename to *.rst
Convert livepatch documentation to ReST format. The changes
are mostly trivial, as the documents are already on a good
shape. Just a few markup changes are needed for Sphinx to
properly parse the docs.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - The in-file TOC becomes a comment, in order to skip it from the
    output, as Sphinx already generates an index there.
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

f678d6da74 Char/Misc patches for 5.2-rc1 - part 2
Here is the "real" big set of char/misc driver patches for 5.2-rc1
 
 Loads of different driver subsystem stuff in here, all over the places:
   - thunderbolt driver updates
   - habanalabs driver updates
   - nvmem driver updates
   - extcon driver updates
   - intel_th driver updates
   - mei driver updates
   - coresight driver updates
   - soundwire driver cleanups and updates
   - fastrpc driver updates
   - other minor driver updates
   - chardev minor fixups
 
 Feels like this tree is getting to be a dumping ground of "small driver
 subsystems" these days.  Which is fine with me, if it makes things
 easier for those subsystem maintainers.
 
 All of these have been in linux-next for a while with no reported
 issues.

2310673c3c Char/Misc patches for 5.2-rc1 - part 1
This is the first pull request for the char/misc driver tree for 5.2-rc1
 
 This contains only a small number of bugfixes that would have gone to
 you for 5.1-rc8 if that had happened, but instead I let them sit in
 linux-next for an extra week just "to be sure".
 
 The "big" patch here is for hyper-v, fixing a bug in their sysfs files
 that could cause big problems.  The others are all small fixes,
 resolving reported issues that showed up in 5.1-rcs, plus some odd
 'static' cleanups for the phy drivers that really should have waited for
 -rc1.  Most of these are tagged for the stable trees, so 5.1 will pick
 them up.
 
 All of these have been in linux-next for a while, with no reported
 issues.

e0dccbdf5a Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
 
 Lots of tiny fixes all over the staging and IIO driver trees here, along
 with some new IIO drivers.
 
 Also we ended up deleting two drivers, making this pull request remove a
 few hundred thousand lines of code, always a nice thing to see.  Both of
 the drivers removed have been replaced with "real" drivers in their
 various subsystem directories, and they will be coming to you from those
 locations during this merge window.
 
 There are some core vt/selection changes in here, that was due to some
 cleanups needed for the speakup fixes.  Those have all been acked by the
 various subsystem maintainers (i.e. me), so those are ok.
 
 We also added a few new drivers, for some odd hardware, giving new
 developers plenty to work on with basic coding style cleanups to come in
 the near future.
 
 Other than that, nothing unusual here.
 
 All of these have been in linux-next for a while with no reported
 issues, other than an odd gcc warning for one of the new drivers that
 should be fixed up soon.

Pull x86 FPU state handling updates from Borislav Petkov:
 "This contains work started by Rik van Riel and brought to fruition by
  Sebastian Andrzej Siewior with the main goal to optimize when to load
  FPU registers: only when returning to userspace and not on every
  context switch (while the task remains in the kernel).

  In addition, this optimization makes kernel_fpu_begin() cheaper by
  requiring registers saving only on the first invocation and skipping
  that in following ones.

  What is more, this series cleans up and streamlines many aspects of
  the already complex FPU code, hopefully making it more palatable for
  future improvements and simplifications.

  Finally, there's a __user annotations fix from Jann Horn"

898490c010 moduleparam: Save information about built-in modules in separate file
Problem:

When a kernel module is compiled as a separate module, some important
information about the kernel module is available via .modinfo section of
the module.  In contrast, when the kernel module is compiled into the
kernel, that information is not available.

Information about built-in modules is necessary in the following cases:

1. When it is necessary to find out what additional parameters can be
passed to the kernel at boot time.

2. When you need to know which module names and their aliases are in
the kernel. This is very useful for creating an initrd image.

Proposal:

The proposed patch does not remove .modinfo section with module
information from the vmlinux at the build time and saves it into a
separate file after kernel linking. So, the kernel does not increase in
size and no additional information remains in it. Information is stored
in the same format as in the separate modules (null-terminated string
array). Because the .modinfo section is already exported with a separate
modules, we are not creating a new API.

It can be easily read in the userspace:

Pull ACPI updates from Rafael Wysocki:
 "These rearrange the ACPI documentation by converting it to the .rst
  format and splitting it into clear categories (admin guide, driver
  API, firmware guide), switch over multiple users of a problematic
  library function to a new better one, update the ACPICA code in the
  kernel to a new upstream release, fix a few issues, improve power
  device management diagnostics and do some cleanups.

  Specifics:

   - Convert the ACPI documentation in the kernel source tree to the
     .rst format and split it into the admin guide, driver API and
     firmware guide parts (Changbin Du).

   - Add a PRP0001 usage example to the ACPI documentation (Thomas
     Preston).

   - Switch over the users of the acpi_dev_get_first_match_name()
     library function which turned out to be problematic to a new,
     better one called acpi_dev_get_first_match_dev() (Andy Shevchenko,
     YueHaibing).

   - Update the ACPICA code in the kernel to upstream release 20190405
     including:
       * Null pointer dereference check in acpi_ns_delete_node() (Erik
         Schmauss).
       * Multiple macro and function name changes (Bob Moore).
       * Predefined operation region name fix (Erik Schmauss).

   - Fix hibernation issue on systems using the Baytrail and Cherrytrail
     Intel SoCs introduced during the 4.20 development cycle (Hans de
     Goede).

   - Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui).

   - Fix button handling during system resume (Zhang Rui).

   - Add a device PM diagnostic message (Rafael Wysocki).

   - Clean up the code, comments and white space in multiple places
     (Bjorn Helgaas, Gustavo Silva, Kefeng Wang)"

d81645510c ASoC: Updates for v5.2
This is a pretty huge set of changes, it's been a pretty active release
 all round but the big thing with this release is the Sound Open Firmware
 changes from Intel, providing another DSP framework for use with the
 DSPs in their SoCs.  This one works with the firmware of the same name
 which is free software (unlike the previous DSP firmwares and framework)
 and there has been some interest in adoption by other systems already so
 hopefully we will see adoption by other vendors in the future.
 
 Other highlights incldue:
 
  - Support for MCLK/sample rate ratio setting in the generic cards.
  - Support for pin switches in the generic cards.
  - A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
    McDermond.
  - New drivers for Freescale audio mixers, several Intel machines,
    several Mediatek machines, Meson G12A, Sound Open Firmware and
    Spreadtrum compressed audio and DMA devices.

As of_get_mac_address now supports NVMEM under the hood, we need to update
the bindings documentation with the new nvmem-cell* properties, which would
mean copy&pasting a lot of redundant information to every binding
documentation currently referencing some of the MAC address properties.

So I've just removed all the references to the optional MAC address
properties and replaced them with the small note referencing
net/ethernet.txt file.

86847dca8b dt-bindings: usb: dwc2: document the vbus-supply property
Various boards have an external VBUS supply regulator. This regulator
depends on the current mode of the controller which is defined as:
- dr_mode set to either "host" or "peripheral" (fixed value)
- dr_mode set to "otg", based on the OTG status the dwc2 controller
  internally switches between "host" and "peripheral" mode (selection
  happens at runtime)

Based on the current mode the regulator has to be enabled or disabled:
- host: provide power to the connected USB device, thus the regulator
  has to be enabled
- peripheral: the host device to which the controller is connected
  provides power, thus the regulator has to be disabled

Add the dt-bindings documentation for this property so .dts authors know
that this property exists and how it behaves.

e8c77fa091 dt-bindings: usb: dwc3: Add Amlogic G12A DWC3 Glue Bindings
Adds the bindings for the Amlogic G12A USB Glue HW.

The Amlogic G12A SoC Family embeds 2 USB Controllers :
- a DWC3 IP configured as Host for USB2 and USB3
- a DWC2 IP configured as Peripheral USB2 Only

A glue connects these both controllers to 2 USB2 PHYs,
and optionnally to an USB3+PCIE Combo PHY shared with the PCIE controller.

The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including
routing of the OTG PHY between the DWC3 and DWC2 controllers, and
setups the on-chip OTG mode selection for this PHY.

The PHYs phandles are passed  to the Glue node since the Glue controls the
interface with the PHY, not the DWC3 controller.

d3b18ad63d dt-bindings: arm: coresight: Unify funnel DT binding
Following the same fashion with replicator DT binding, this patch is to
unify the DT binding for funnel to support static and dynamic modes;
finally we get the funnel DT binding as below:

Before patch:

  Static funnel, aka. non-configurable funnel:
    Not supported;

  Dynamic funnel, aka. configurable funnel:
    "arm,coresight-funnel", "arm,primecell";

After patch:

  Static funnel:
    "arm,coresight-static-funnel";

  Dynamic funnel:
    "arm,coresight-dynamic-funnel", "arm,primecell";
    "arm,coresight-funnel", "arm,primecell"; (obsolete)

At the end of this patch, it gives an example for static funnel DT
binding, and updates the dynamic funnel example.

635b90f47d dt-bindings: arm: coresight: Add new compatible for static replicator
CoreSight uses below bindings for replicator:

  Dynamic replicator, aka. configurable replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";

  Static replicator, aka. non-configurable replicator:
    "arm,coresight-replicator";

The compatible string "arm,coresight-replicator" is not an explicit
naming to express the replicator is 'static'.  To unify the naming
convention, this patch introduces a new compatible string
"arm,coresight-static-replicator" for the static replicator; the
compatible string "arm,coresight-replicator" is kept for backward
compatibility, but tag it as obsolete and suggest to use the new
compatible string.

As result CoreSight replicator have below bindings:

  Dynamic replicator:
    "arm,coresight-dynamic-replicator", "arm,primecell";

  Static replicator:
    "arm,coresight-static-replicator";
    "arm,coresight-replicator"; (obsolete)

fdb0da89f4 new inode method: ->free_inode()
A lot of ->destroy_inode() instances end with call_rcu() of a callback
that does RCU-delayed part of freeing.  Introduce a new method for
doing just that, with saner signature.

Rules:
->destroy_inode		->free_inode
	f			g		immediate call of f(),
						RCU-delayed call of g()
	f			NULL		immediate call of f(),
						no RCU-delayed calls
	NULL			g		RCU-delayed call of g()
	NULL			NULL		RCU-delayed default freeing

IOW, NULL ->free_inode gives the same behaviour as now.

Note that NULL, NULL is equivalent to NULL, free_inode_nonrcu; we could
mandate the latter form, but that would have very little benefit beyond
making rules a bit more symmetric.  It would break backwards compatibility,
require extra boilerplate and expected semantics for (NULL, NULL) pair
would have no use whatsoever...

813cab8f39 power: supply: core: Add CHARGE_CONTROL_{START_THRESHOLD,END_THRESHOLD} properties
Add POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD
and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties, to expand
the existing CHARGE_CONTROL_* properties. I am adding them in order
to support a new Chrome OS device, but these properties should be
general enough that they can be used on other devices.

When the charge_type is "Custom", the charge controller uses the
POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some
other algorithm. For example, in the use case that I am supporting,
this means the battery begins charging when the percentage
level drops below POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and
charging ceases when the percentage level goes above
POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD.

v5 changes:
- Add the other missing CHARGE_CONTROL_* properties documentation in
  a separate commit
- Split up adding the charge types and adding the
  POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and
  POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties into
  two different commits.
v4 changes:
- Add documentation for the new properties, and add documentation for

ba6cc85084 power: supply: core: Add Standard, Adaptive, and Custom charge types
Add "Standard", "Adaptive", and "Custom" modes to the charge_type
property, to expand the existing "Trickle" and "Fast" modes.
I am adding them in order to support a new Chrome OS device,
but these properties should be general enough that they can be
used on other devices.

The meaning of "Standard" is obvious, but "Adaptive" and "Custom" are
more tricky: "Adaptive" means that the charge controller uses some
custom algorithm to change the charge type automatically, with no
configuration needed. "Custom" means that the charge controller uses the
POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some
other algorithm.

e4f3fabd67 dm: add dust target
Add the dm-dust target, which simulates the behavior of bad sectors
at arbitrary locations, and the ability to enable the emulation of
the read failures at an arbitrary time.

This target behaves similarly to a linear target.  At a given time,
the user can send a message to the target to start failing read
requests on specific blocks.  When the failure behavior is enabled,
reads of blocks configured "bad" will fail with EIO.

Writes of blocks configured "bad" will result in the following:

1. Remove the block from the "bad block list".
2. Successfully complete the write.

After this point, the block will successfully contain the written
data, and will service reads and writes normally.  This emulates the
behavior of a "remapped sector" on a hard disk drive.

dm-dust provides logging of which blocks have been added or removed
to the "bad block list", as well as logging when a block has been
removed from the bad block list.  These messages can be used
alongside the messages from the driver using a dm-dust device to
analyze the driver's behavior when a read fails at a given time.

(This logging can be reduced via a "quiet" mode, if desired.)

NOTE: If the block size is larger than 512 bytes, only the first sector
of each "dust block" is detected.  Placing a limiting layer above a dust
target, to limit the minimum I/O size to the dust block size, will
ensure proper emulation of the given large block size.

If a memory slot's size is not a multiple of 64 pages (256K), then

either requires the requested page range to go beyond memslot->npages,

232b984b7d KVM: PPC: Book3S HV: XIVE: Add passthrough support
The KVM XICS-over-XIVE device and the proposed KVM XIVE native device
implement an IRQ space for the guest using the generic IPI interrupts
of the XIVE IC controller. These interrupts are allocated at the OPAL
level and "mapped" into the guest IRQ number space in the range 0-0x1FFF.
Interrupt management is performed in the XIVE way: using loads and
stores on the addresses of the XIVE IPI interrupt ESB pages.

Both KVM devices share the same internal structure caching information
on the interrupts, among which the xive_irq_data struct containing the
addresses of the IPI ESB pages and an extra one in case of pass-through.
The later contains the addresses of the ESB pages of the underlying HW
controller interrupts, PHB4 in all cases for now.

A guest, when running in the XICS legacy interrupt mode, lets the KVM
XICS-over-XIVE device "handle" interrupt management, that is to
perform the loads and stores on the addresses of the ESB pages of the
guest interrupts. However, when running in XIVE native exploitation
mode, the KVM XIVE native device exposes the interrupt ESB pages to
the guest and lets the guest perform directly the loads and stores.

The VMA exposing the ESB pages make use of a custom VM fault handler
which role is to populate the VMA with appropriate pages. When a fault
occurs, the guest IRQ number is deduced from the offset, and the ESB
pages of associated XIVE IPI interrupt are inserted in the VMA (using
the internal structure caching information on the interrupts).

Supporting device passthrough in the guest running in XIVE native
exploitation mode adds some extra refinements because the ESB pages
of a different HW controller (PHB4) need to be exposed to the guest
along with the initial IPI ESB pages of the XIVE IC controller. But
the overall mechanic is the same.

When the device HW irqs are mapped into or unmapped from the guest
IRQ number space, the passthru_irq helpers, kvmppc_xive_set_mapped()
and kvmppc_xive_clr_mapped(), are called to record or clear the
passthrough interrupt information and to perform the switch.

The approach taken by this patch is to clear the ESB pages of the
guest IRQ number being mapped and let the VM fault handler repopulate.
The handler will insert the ESB page corresponding to the HW interrupt
of the device being passed-through or the initial IPI ESB page if the
device is being removed.

Each thread has an associated Thread Interrupt Management context
composed of a set of registers. These registers let the thread handle
priority management and interrupt acknowledgment. The most important
are :

    - Interrupt Pending Buffer     (IPB)
    - Current Processor Priority   (CPPR)
    - Notification Source Register (NSR)

They are exposed to software in four different pages each proposing a
view with a different privilege. The first page is for the physical
thread context and the second for the hypervisor. Only the third
(operating system) and the fourth (user level) are exposed the guest.

A custom VM fault handler will populate the VMA with the appropriate
pages, which should only be the OS page for now.

e6714bd167 KVM: PPC: Book3S HV: XIVE: Add a control to dirty the XIVE EQ pages
When migration of a VM is initiated, a first copy of the RAM is
transferred to the destination before the VM is stopped, but there is
no guarantee that the EQ pages in which the event notifications are
queued have not been modified.

To make sure migration will capture a consistent memory state, the
XIVE device should perform a XIVE quiesce sequence to stop the flow of
event notifications and stabilize the EQs. This is the purpose of the
KVM_DEV_XIVE_EQ_SYNC control which will also marks the EQ pages dirty
to force their transfer.

These controls will be used by the H_INT_SET_QUEUE_CONFIG and
H_INT_GET_QUEUE_CONFIG hcalls from QEMU to configure the underlying
Event Queue in the XIVE IC. They will also be used to restore the

The value of the guest physical address of the event queue is saved in
the XIVE internal xive_q structure for later use. That is when
migration needs to mark the EQ pages dirty to capture a consistent
memory state of the VM.

To be noted that H_INT_SET_QUEUE_CONFIG does not require the extra
OPAL call setting the EQ toggle bit and EQ index to configure the EQ,
but restoring the EQ state will.

4131f83c3d KVM: PPC: Book3S HV: XIVE: add a control to initialize a source
The XIVE KVM device maintains a list of interrupt sources for the VM
which are allocated in the pool of generic interrupts (IPIs) of the
main XIVE IC controller. These are used for the CPU IPIs as well as
for virtual device interrupts. The IRQ number space is defined by
QEMU.

The XIVE device reuses the source structures of the XICS-on-XIVE
device for the source blocks (2-level tree) and for the source
interrupts. Under XIVE native, the source interrupt caches mostly
configuration information and is less used than under the XICS-on-XIVE
device in which hcalls are still necessary at run-time.

When a source is initialized in KVM, an IPI interrupt source is simply
allocated at the OPAL level and then MASKED. KVM only needs to know
about its type: LSI or MSI.

1895ef4ef2 This modernizes the IXP4xx platform and adds initial Device Tree
Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to
 offset 16, converts to SPARSE_IRQ, then we add proper subsystem
 drivers in each subsystem for irqchip, GPIO and clocksource and
 switch over to using these new drivers.
 
 Next we modernize the NPE and QMGR drivers and push them down
 into drivers/soc.
 
 This has been tested on the IXP4xx NSLU2 and the Gateworks
 GW2358-4.

e639861344 Driver changes for ti-sysc for v5.2 merge window
This series of changes for ti-sysc interconnect target module driver
 gets us to the point where we can actually drop legacy platform data
 for many devices in favor of device tree data.
 
 To do this, we improve ti-sysc driver not to rely on platform data
 callbacks to manage module clocks, and handle more quirks needed for
 some devices. Also few minor fixes are needed, but were considered
 not needed to be sent separately as they only show up with this series.
 
 Then we drop several thousands of lines of legacy platform data for
 omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc,
 i2c, gpio and uart devices to start with as those are typically
 easily tested on all devices. In case of unexpected issues, we can just
 add back the legacy platform data for a single device type if needed.
 
 Finally we add initial support for enabling and disabling some devices
 without legacy platform data callbacks. I was planning on sending the
 dropping of legacy platform data as a separate series, but already
 applied Roger's patch on top and pushed it out.
 
 Note that this series depends on related SoC and is based on those.

c8e3993dd5 dt-bindings: hwmon (pwm-fan) Remove dead "cooling-*-state" properties
The old "cooling-{min,max}-state" properties for thermal bindings were
ratified to "cooling-{min,max}-level" by commit eb168b70de ("of:
thermal: Fix inconsitency between cooling-*-state and cooling-*-level"),
which were later removed entirely by commit e04907dbc2 ("dt-bindings:
thermal: Remove "cooling-{min|max}-level" properties").

The pwm-fan binding, however, was apparently in-flight in parallel with
that ratification, and so managed to introduce an example of the old
properties which escaped the scope of the later cleanup and has thus
continued to be dutifully copied for new boards despite being useless.
Clean up these remaining undocumented anachronisms to minimise any
further confusion.

da9a4c3d32 Devicetree changes for omap4 and 5 l4 abe interconnect
This series of devicetree changes adds the l4 abe interconnect devices
 and moves the devices to their right places in the hierarchy similar
 to what we've already done for most l4 devices earlier. We first add
 a shared omap4-mcpdm.dtsi to make adding omap4-l4-abe.dtsi easier for
 the mcpdm changes. And as earlier, in case of unexpected trouble,
 devices can be probed the old way by moving one device at a time to the
 old place.
 
 This series of changes depends on the ti-sysc driver changes for handling
 the external optional clocks that the mcpdm relies on, and is based on
 the related ti-sysc driver changes. Note that this series does not depend
 on dropping of the leagcy platform data, but I already had those committed
 along with the ti-sysc driver changes and noticed too late.

28ba53c076 unicode: refactor the rule for regenerating utf8data.h
scripts/mkutf8data is used only when regenerating utf8data.h,
which never happens in the normal kernel build. However, it is
irrespectively built if CONFIG_UNICODE is enabled.

Moreover, there is no good reason for it to reside in the scripts/
directory since it is only used in fs/unicode/.

Hence, move it from scripts/ to fs/unicode/.

In some cases, we bypass build artifacts in the normal build. The
conventional way to do so is to surround the code with ifdef REGENERATE_*.

For example,

 - 7373f4f83c ("kbuild: add implicit rules for parser generation")
 - 6aaf49b495 ("crypto: arm,arm64 - Fix random regeneration of S_shipped")

I rewrote the rule in a more kbuild'ish style.

In the normal build, utf8data.h is just shipped from the check-in file.

$ make
  [ snip ]
  SHIPPED fs/unicode/utf8data.h
  CC      fs/unicode/utf8-norm.o
  CC      fs/unicode/utf8-core.o
  CC      fs/unicode/utf8-selftest.o
  AR      fs/unicode/built-in.a

If you want to generate utf8data.h based on UCD, put *.txt files into
fs/unicode/, then pass REGENERATE_UTF8DATA=1 from the command line.
The mkutf8data tool will be automatically compiled to generate the
utf8data.h from the *.txt files.

$ make REGENERATE_UTF8DATA=1
  [ snip ]
  HOSTCC  fs/unicode/mkutf8data
  GEN     fs/unicode/utf8data.h
  CC      fs/unicode/utf8-norm.o
  CC      fs/unicode/utf8-core.o
  CC      fs/unicode/utf8-selftest.o
  AR      fs/unicode/built-in.a

I renamed the check-in utf8data.h to utf8data.h_shipped so that this
will work for the out-of-tree build.

You can update it based on the latest UCD like this:

$ make REGENERATE_UTF8DATA=1 fs/unicode/
$ cp fs/unicode/utf8data.h fs/unicode/utf8data.h_shipped

Also, I added entries to .gitignore and dontdiff.

24512228b7 mm: do not boost watermarks to avoid fragmentation for the DISCONTIG memory model
Mikulas Patocka reported that commit 1c30844d2d ("mm: reclaim small
amounts of memory when an external fragmentation event occurs") "broke"
memory management on parisc.

The machine is not NUMA but the DISCONTIG model creates three pgdats
even though it's a UMA machine for the following ranges

        0) Start 0x0000000000000000 End 0x000000003fffffff Size   1024 MB
        1) Start 0x0000000100000000 End 0x00000001bfdfffff Size   3070 MB
        2) Start 0x0000004040000000 End 0x00000040ffffffff Size   3072 MB

Mikulas reported:

	With the patch 1c30844d2, the kernel will incorrectly reclaim the
	first zone when it fills up, ignoring the fact that there are two
	completely free zones. Basiscally, it limits cache size to 1GiB.

	For example, if I run:
	# dd if=/dev/sda of=/dev/null bs=1M count=2048

	- with the proper kernel, there should be "Buffers - 2GiB"
	when this command finishes. With the patch 1c30844d2, buffers
	will consume just 1GiB or slightly more, because the kernel was
	incorrectly reclaiming them.

The page allocator and reclaim makes assumptions that pgdats really
represent NUMA nodes and zones represent ranges and makes decisions on
that basis.  Watermark boosting for small pgdats leads to unexpected
results even though this would have behaved reasonably on SPARSEMEM.

DISCONTIG is essentially deprecated and even parisc plans to move to
SPARSEMEM so there is no need to be fancy, this patch simply disables
watermark boosting by default on DISCONTIGMEM.

635720ac75 vsprintf: Avoid confusion between invalid address and value
We are able to detect invalid values handled by %p[iI] printk specifier.
The current error message is "invalid address". It might cause confusion
against "(efault)" reported by the generic valid_pointer_address() check.

Let's unify the style and use the more appropriate error code description
"(einval)".

3e5903eb9c vsprintf: Prevent crash when dereferencing invalid pointers
We already prevent crash when dereferencing some obviously broken
pointers. But the handling is not consistent. Sometimes we print "(null)"
only for pure NULL pointer, sometimes for pointers in the first
page and sometimes also for pointers in the last page (error codes).

Note that printk() call this code under logbuf_lock. Any recursive
printks are redirected to the printk_safe implementation and the messages
are stored into per-CPU buffers. These buffers might be eventually flushed
in printk_safe_flush_on_panic() but it is not guaranteed.

This patch adds a check using probe_kernel_read(). It is not a full-proof
test. But it should help to see the error message in 99% situations where
the kernel would silently crash otherwise.

Also it makes the error handling unified for "%s" and the many %p*
specifiers that need to read the data from a given address. We print:

   + (null)   when accessing data on pure pure NULL address
   + (efault) when accessing data on an invalid address

It does not affect the %p* specifiers that just print the given address
in some form, namely %pF, %pf, %pS, %ps, %pB, %pK, %px, and plain %p.

Note that we print (efault) from security reasons. In fact, the real
address can be seen only by %px or eventually %pK.
