Tracing changes for v4.21:
- Rework of the kprobe/uprobe and synthetic events to consolidate all
the dynamic event code. This will make changes in the future easier.
- Partial rewrite of the function graph tracing infrastructure.
This will allow for multiple users of hooking onto functions
to get the callback (return) of the function. This is the ground
work for having kprobes and function graph tracer using one code base.
- Clean up of the histogram code that will facilitate adding more
features to the histograms in the future.
- Addition of str_has_prefix() and a few use cases. There currently
is a similar function strstart() that is used in a few places, but
only returns a bool and not a length. These instances will be
removed in the future to use str_has_prefix() instead.
- A few other various clean ups as well.

f2fs-for-4.21-rc1
In this round, we've focused on bug fixes since Pixel devices have been shipping with f2fs. Some of them were related to hardware encryption support which are actually not an issue in mainline, but would be better to merge them in order to avoid potential bugs.

lib: don't depend on linux headers being installed.
gen_crc64table requires linux include files to be installed in
/usr/include/linux. This is a new requrement so hosts that could
previously build the kernel, now cannot.
gen_crc64table makes this requirement by including <linux/swab.h>, but
nothing from that header is actaully used.
So remove the #include, so that the linux headers no longer need to be
installed.
Fixes:

Char/Misc driver patches for 4.21-rc1
Here is the big set of char and misc driver patches for 4.21-rc1.
Lots of different types of driver things in here, as this tree seems to
be the "collection of various driver subsystems not big enough to have
their own git tree" lately.
Anyway, some highlights of the changes in here:
- binderfs: is it a rule that all driver subsystems will eventually
grow to have their own filesystem? Binder now has one to handle the
use of it in containerized systems. This was discussed at the
Plumbers conference a few months ago and knocked into mergable shape
very fast by Christian Brauner. Who also has signed up to be
another binder maintainer, showing a distinct lack of good judgement :)
- binder updates and fixes
- mei driver updates
- fpga driver updates and additions
- thunderbolt driver updates
- soundwire driver updates
- extcon driver updates
- nvmem driver updates
- hyper-v driver updates
- coresight driver updates
- pvpanic driver additions and reworking for more device support
- lp driver updates. Yes really, it's _finally_ moved to the proper
parallal port driver model, something I never thought I would see
happen. Good stuff.
- other tiny driver updates and fixes.
All of these have been in linux-next for a while with no reported
issues.

Merge tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:
"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.
- New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
PHY, and Xen shared memory
- Update dtc to upstream version v1.4.7-57-gf267e674d145"

This is the bulk of GPIO changes for the v4.21 kernel series:
Core changes:
- Some core changes are already in outside of this pull
request as they came through the regulator tree, most
notably devm_gpiod_unhinge() that removes devres refcount
management from a GPIO descriptor. This is needed in
subsystems such as regulators where the regulator core
need to take over the reference counting and lifecycle
management for a GPIO descriptor.
- We dropped devm_gpiochip_remove() and devm_gpio_chip_match()
as nothing needs it. We can bring it back if need be.
- Add a global TODO so people see where we are going. This
helps setting the direction now that we are two GPIO
maintainers.
- Handle the MMC CD/WP properties in the device tree core.
(The bulk of patches activating this code is already
merged through the MMC/SD tree.)
- Augment gpiochip_request_own_desc() to pass a flag so
we as gpiochips can request lines as active low or open
drain etc even from ourselves.
New drivers:
- New driver for Cadence GPIO blocks.
- New driver for Atmel SAMA5D2 PIOBU GPIO lines.
Driver improvements:
- A major refactoring of the PCA953x driver - this driver has
been around for ages, and is now modernized to reduce code
duplication that has stacked up and is using regmap to read
write and cache registers.
- Intel drivers are now maintained in a separate tree and
start with a round of cleanups and unifications.

libnvdimm for 4.21
* Add support for the security features of nvdimm devices that
implement a security model similar to ATA hard drive security. The
security model supports locking access to the media at
device-power-loss, to be unlocked with a passphrase, and secure-erase
(crypto-scramble).
Unlike the ATA security case where the kernel expects device
security to be managed in a pre-OS environment, the libnvdimm security
implementation allows key provisioning and key-operations at OS
runtime. Keys are managed with the kernel's encrypted-keys facility to
provide data-at-rest security for the libnvdimm key material. The
usage model mirrors fscrypt key management, but is driven via
libnvdimm sysfs.
* Miscellaneous updates for api usage and comment fixes.

Merge tag 'libnvdimm-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The vast bulk of this update is the new support for the security
capabilities of some nvdimms.
The userspace tooling for this capability is still a work in progress,
but the changes survive the existing libnvdimm unit tests. The changes
also pass manual checkout on hardware and the new nfit_test emulation
of the security capability.
The touches of the security/keys/ files have received the necessary
acks from Mimi and David. Those changes were necessary to allow for a
new generic encrypted-key type, and allow the nvdimm sub-system to
lookup key material referenced by the libnvdimm-sysfs interface.

DMA mapping updates for Linux 4.21
A huge update this time, but a lot of that is just consolidating or
removing code:
- provide a common DMA_MAPPING_ERROR definition and avoid indirect
calls for dma_map_* error checking
- use direct calls for the DMA direct mapping case, avoiding huge
retpoline overhead for high performance workloads
- merge the swiotlb dma_map_ops into dma-direct
- provide a generic remapping DMA consistent allocator for architectures
that have devices that perform DMA that is not cache coherent. Based
on the existing arm64 implementation and also used for csky now.
- improve the dma-debug infrastructure, including dynamic allocation
of entries (Robin Murphy)
- default to providing chaining scatterlist everywhere, with opt-outs
for the few architectures (alpha, parisc, most arm32 variants) that
can't cope with it
- misc sparc32 dma-related cleanups
- remove the dma_mark_clean arch hook used by swiotlb on ia64 and

Pull DMA mapping updates from Christoph Hellwig:
"A huge update this time, but a lot of that is just consolidating or
removing code:
- provide a common DMA_MAPPING_ERROR definition and avoid indirect
calls for dma_map_* error checking
- use direct calls for the DMA direct mapping case, avoiding huge
retpoline overhead for high performance workloads
- merge the swiotlb dma_map_ops into dma-direct
- provide a generic remapping DMA consistent allocator for
architectures that have devices that perform DMA that is not cache
coherent. Based on the existing arm64 implementation and also used
for csky now.
- improve the dma-debug infrastructure, including dynamic allocation
of entries (Robin Murphy)
- default to providing chaining scatterlist everywhere, with opt-outs
for the few architectures (alpha, parisc, most arm32 variants) that
can't cope with it
- misc sparc32 dma-related cleanups
- remove the dma_mark_clean arch hook used by swiotlb on ia64 and
replace it with the generic noncoherent infrastructure
- fix the return type of dma_set_max_seg_size (Niklas Söderlund)

Pull block updates from Jens Axboe:
"This is the main pull request for block/storage for 4.21.
Larger than usual, it was a busy round with lots of goodies queued up.
Most notable is the removal of the old IO stack, which has been a long
time coming. No new features for a while, everything coming in this
week has all been fixes for things that were previously merged.
This contains:
- Use atomic counters instead of semaphores for mtip32xx (Arnd)
- Cleanup of the mtip32xx request setup (Christoph)
- Fix for circular locking dependency in loop (Jan, Tetsuo)
- bcache (Coly, Guoju, Shenghui)
* Optimizations for writeback caching
* Various fixes and improvements
- nvme (Chaitanya, Christoph, Sagi, Jay, me, Keith)
* host and target support for NVMe over TCP
* Error log page support
* Support for separate read/write/poll queues
* Much improved polling
* discard OOM fallback
* Tracepoint improvements
- lightnvm (Hans, Hua, Igor, Matias, Javier)
* Igor added packed metadata to pblk. Now drives without metadata
per LBA can be used as well.
* Fix from Geert on uninitialized value on chunk metadata reads.
* Fixes from Hans and Javier to pblk recovery and write path.
* Fix from Hua Su to fix a race condition in the pblk recovery
code.
* Scan optimization added to pblk recovery from Zhoujie.
* Small geometry cleanup from me.
- Conversion of the last few drivers that used the legacy path to
blk-mq (me)
- Removal of legacy IO path in SCSI (me, Christoph)
- Removal of legacy IO stack and schedulers (me)
- Support for much better polling, now without interrupts at all.
blk-mq adds support for multiple queue maps, which enables us to
have a map per type. This in turn enables nvme to have separate
completion queues for polling, which can then be interrupt-less.
Also means we're ready for async polled IO, which is hopefully
coming in the next release.
- Killing of (now) unused block exports (Christoph)
- Unification of the blk-rq-qos and blk-wbt wait handling (Josef)
- Support for zoned testing with null_blk (Masato)
- sx8 conversion to per-host tag sets (Christoph)
- IO priority improvements (Damien)
- mq-deadline zoned fix (Damien)
- Ref count blkcg series (Dennis)
- Lots of blk-mq improvements and speedups (me)
- sbitmap scalability improvements (me)
- Make core inflight IO accounting per-cpu (Mikulas)
- Export timeout setting in sysfs (Weiping)
- Cleanup the direct issue path (Jianchao)
- Export blk-wbt internals in block debugfs for easier debugging
(Ming)
- Lots of other fixes and improvements"

y2038: more syscalls and cleanups
This concludes the main part of the system call rework for 64-bit time_t,
which has spread over most of year 2018, the last six system calls being
- ppoll
- pselect6
- io_pgetevents
- recvmmsg
- futex
- rt_sigtimedwait
As before, nothing changes for 64-bit architectures, while 32-bit
architectures gain another entry point that differs only in the layout
of the timespec structure. Hopefully in the next release we can wire up
all 22 of those system calls on all 32-bit architectures, which gives
us a baseline version for glibc to start using them.
This does not include the clock_adjtime, getrusage/waitid, and
getitimer/setitimer system calls. I still plan to have new versions
of those as well, but they are not required for correct operation of
the C library since they can be emulated using the old 32-bit time_t
based system calls.
Aside from the system calls, there are also a few cleanups here,
removing old kernel internal interfaces that have become unused after
all references got removed. The arch/sh cleanups are part of this,
there were posted several times over the past year without a reaction
from the maintainers, while the corresponding changes made it into all
other architectures.

mm, swap: fix swapoff with KSM pages
KSM pages may be mapped to the multiple VMAs that cannot be reached from one anon_vma. So during swapin, a new copy of the page need to be generated if a different anon_vma is needed, please refer to comments of ksm_might_need_to_copy() for details. During swapoff, unuse_vma() uses anon_vma (if available) to locate VMA and virtual address mapped to the page, so not all mappings to a swapped out KSM page could be found. So in try_to_unuse(), even if the swap count of a swap entry isn't zero, the page needs to be deleted from swap cache, so that, in the next round a new page could be allocated and swapin for the other mappings of the swapped out KSM page. But this contradicts with the THP swap support. Where the THP could be deleted from swap cache only after the swap count of every swap entry in the huge swap cluster backing the THP has reach 0. So try_to_unuse() is changed in commit |

mm/hmm: fix memremap.h, move dev_page_fault_t callback to hmm
The kbuild robot reported the following on a development branch that used
memremap.h in a new path:
In file included from arch/m68k/include/asm/pgtable_mm.h:148:0,
from arch/m68k/include/asm/pgtable.h:5,
from include/linux/memremap.h:7,

>> arch/m68k/include/asm/motorola_pgtable.h:199:11: error: dereferencing pointer to incomplete type 'const struct mm_struct'
return mm->pgd + pgd_index(address);
^~
The ->page_fault() callback is specific to HMM. Move it to 'struct
hmm_devmem' where the unusual asm/pgtable.h dependency can be contained in
include/linux/hmm.h. Longer term refactoring this dependency out of HMM
is recommended, but in the meantime memremap.h remains generic.

hugetlbfs: Use i_mmap_rwsem to fix page fault/truncate race
hugetlbfs page faults can race with truncate and hole punch operations.
Current code in the page fault path attempts to handle this by 'backing
out' operations if we encounter the race. One obvious omission in the
current code is removing a page newly added to the page cache. This is
pretty straight forward to address, but there is a more subtle and
difficult issue of backing out hugetlb reservations. To handle this
correctly, the 'reservation state' before page allocation needs to be
noted so that it can be properly backed out. There are four distinct
possibilities for reservation state: shared/reserved, shared/no-resv,
private/reserved and private/no-resv. Backing out a reservation may
require memory allocation which could fail so that needs to be taken into
account as well.
Instead of writing the required complicated code for this rare occurrence,
just eliminate the race. i_mmap_rwsem is now held in read mode for the
duration of page fault processing. Hold i_mmap_rwsem longer in truncation
and hold punch code to cover the call to remove_inode_hugepages.
With this modification, code in remove_inode_hugepages checking for races
becomes 'dead' as it can not longer happen. Remove the dead code and
expand comments to explain reasoning. Similarly, checks for races with
truncation in the page fault path can be simplified and removed.

discovered and observed that a huge pte pointer could become 'invalid' and
point to another task's page table. Consider the following:
A task takes a page fault on a shared hugetlbfs file and calls
huge_pte_alloc to get a ptep. Suppose the returned ptep points to a
shared pmd.
Now, another task truncates the hugetlbfs file. As part of truncation, it
unmaps everyone who has the file mapped. If the range being truncated is
covered by a shared pmd, huge_pmd_unshare will be called. For all but the
last user of the shared pmd, huge_pmd_unshare will clear the pud pointing
to the pmd. If the task in the middle of the page fault is not the last
user, the ptep returned by huge_pte_alloc now points to another task's
page table or worse. This leads to bad things such as incorrect page
map/reference counts or invalid memory references.
To fix, expand the use of i_mmap_rwsem as follows:
- i_mmap_rwsem is held in read mode whenever huge_pmd_share is called.
huge_pmd_share is only called via huge_pte_alloc, so callers of
huge_pte_alloc take i_mmap_rwsem before calling. In addition, callers
of huge_pte_alloc continue to hold the semaphore until finished with the
ptep.
- i_mmap_rwsem is held in write mode whenever huge_pmd_unshare is
called.

memory_hotplug: add missing newlines to debugging output
pages_correctly_probed is missing new lines which means that the line is
not printed rightaway but it rather waits for additional printks.
Add \n to all three messages in pages_correctly_probed.

mm: remove __hugepage_set_anon_rmap()
This function is identical to __page_set_anon_rmap() since the time, when it was introduced (8 years ago). The patch removes the function, and makes its users to use __page_set_anon_rmap() instead.
