3a461da1d0 cls_bpf: reset class and reuse major in da
There are two issues with the current code. First one is that we need
to set res->class to 0 in case we use non-default classid matching.

This is important for the case where cls_bpf was initially set up with
an optional binding to a default class with tcf_bind_filter(), where
the underlying qdisc implements bind_tcf() that fills res->class and
tests for it later on when doing the classification. Convention for
these cases is that after tc_classify() was called, such qdiscs (atm,
drr, qfq, cbq, hfsc, htb) first test class, and if 0, then they lookup
based on classid.

Second, there's a bug with da mode, where res->classid is only assigned
a 16 bit minor, but it needs to expand to the full 32 bit major/minor
combination instead, therefore we need to expand with the bound major.
This is fine as classes belonging to a classful qdisc must share the
same major.

70063e9499 Merge branch 'ldmvsw'
Aaron Young says:

====================
ldmvsw: Add ldmvsw driver

This series adds a new Logical Domains vSwitch (ldmvsw) driver.

The ldmvsw driver code will live in the drivers/net/ethernet/sun/
directory and will operate on Oracle systems running SPARC Linux in a
Logical Domains environment (typically in the control domain).

The ldmvsw driver is very similar in function to the existing sunvnet
driver. Ldmvsw creates a network interface for each "vsw-port" node
found in the Machine Description (MD) of a service domain. These
nodes correspond to ports on a vswitch created by the logical domains
manager. The created network interface(s) can be used by bridge/vswitch
software (such as the Linux bridge or Open vSwitch) to provide
guest domain(s) with network interconnectivity or connectivity
to a physical network.

Here is a example diagram of ldmvsw driver usage in a logical
domain environment to provide a guest domain with network connectivity
to a physical NIC on the service domain:

   +----------------+             +-----------------
   | Service Domain |             |  Guest domain  |
   |                |             |                |
   |  LinuxBridge   |             |                |
   |    |    |      |             |                |
   |   NIC Ldmvsw   |             |    Sunvnet     |
   +----------------+             +----------------+
        |    |           LDC              |
       LAN   ------------------------------

As stated, the sunvnet and ldmvsw drivers are _very_ similar in function.
They both create network interface(s) to receive/transmit network
traffic across LDC network channel(s). Since the driver is so similar
in function to sunvnet, the approach will be as follows to integrate
the driver and take advantage of common code:

Patch #1: Split sunvnet.c driver into sunvnet.c and sunvnet_common.c
Patch #2: Modify the sunvnet_common code and data structures to be compatible
          with both the sunvnet and ldmvsw drivers.
Patch #3: Add the new ldmvsw.c driver code
Patch #4: Checkpatch cleanup of the sunvnet/sunvnet_common code.

NOTE - Patch#1 renames a file (sunvnet.h -> sunvnet_common.h). When generating
the patches (using git format-patch), I had to use the --no-renames option
otherwise patch#1 would NOT apply using 'patch -p1' - which as I
understand is a requirement for patch acceptance. I wasn't sure if this
is proper thing to do.  Please advise if not. Thanks.

v2 changes:
  * change all EXPORT_SYMBOL declarations to EXPORT_SYMBOL_GPL
  * remove inline attribute for external function port_is_up_common()
  * Give all exported/global funcs in sunvnet_common.c a 'sunvnet_' prefix
    to avoid kernel global namespace pollution/collisions
  * ldmvsw.c: Order local variable declarations from longest to shortest line
  * ldmvsw.c: register the netdevice after all supporting state is ready/setup.
              NOTE: The consensus at Oracle is that the following functions
                    must be done AFTER register_netdev() - this is the same
                    ordering currently used in the sunvnet driver:
                    1. sunvnet_port_add_txq_common() - needs registered netdev
                    2. napi_enable() - requires registered netdev
                    3. vio_port_up() - as soon as this function is called
                                       LDC handshake messages will come in
                                       which must be handled by the napi code.

5d01fa0c6b ldmvsw: Add ldmvsw.c driver code
Add ldmvsw.c driver

  Details:

  The ldmvsw driver very closely follows the sunvnet.c code and makes
  use of the sunvnet_common.c code for core functionality.

  A significant difference between sunvnet and ldmvsw driver is
  sunvnet creates a network interface for each vnet-port *parent*
  node in the MD while the ldmvsw driver creates a network interface
  for every vsw-port node in the Machine Description (MD).
  Therefore the netdev_priv() for sunvnet is a vnet structure while
  the netdev_priv() for ldmvsw is a vnet_port structure.

  Vnet_port structures allocated by ldmvsw have the vsw bit set.
  When finding the net_device associated with a port, the common code keys
  off this bit to use either the net_device found in the vnet_port or the
  net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in
  sunvnet_common.h). This scheme allows the common code to work with
  both drivers with minimal changes.

  Similar to Xen, network interfaces created by the ldmvsw driver will always
  have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be
  assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and
  <port_id> are a unique handle/port pair assigned to the associated
  vsw-port node in the MD.

67d0719f06 ldmvsw: Make sunvnet_common compatible with ldmvsw
Modify sunvnet common code and data structures to be compatible
  with both sunvnet and ldmvsw drivers.

  Details:

  Sunvnet operates on "vnet-port" nodes which appear in the Machine
  Description (MD) in a guest domain. Ldmvsw operates on "vsw-port"
  nodes which appear in the MD of a service domain.

  A difference between the sunvnet driver and the ldmvsw driver is
  the sunvnet driver creates a network interface (i.e. a struct net_device)
  for every vnet-port *parent* "network" node. Several vnet-ports may appear
  under this common parent network node - each corresponding to a common parent
  network interface.  Conversely, since bridge/vswitch software will need
  to interface with every vsw-port in a system, the ldmvsw driver creates
  a network interface (i.e. a struct net_device) for every vsw-port - not
  every parent node as with sunvnet.  This difference required some special
  handling in the common code as explained below.

  There are 2 key data structures used by the sunvnet and ldmvsw drivers
  (which are now found in sunvnet_common.h):

  1. struct vnet_port
     This structure represents a vnet-port node in sunvnet and a vsw-port
     in the ldmvsw driver.

  2. struct vnet
     This structure represents a parent "network" node in sunvnet and a parent
     "virtual-network-switch" node in ldmvsw.

  Since the sunvnet driver allocates a net_device for every parent "network"
  node, a net_device member appears in the struct vnet. Since the ldmvsw
  driver allocates a net_device for every port, a net_device member was
  added to the vnet_port. The common code distinguishes which structure
  net_device member to use by checking a 'vsw' bit that was added to the
  vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in
  sunvnet_common.h.

  The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv()
  in ldmvsw is a vnet_port. Therefore, any place in the common code
  where a netdev_priv() call was made, a wrapper function was implemented
  in each driver to first get the vnet and/or vnet_port (in a driver
  specific way) and pass them as newly added parameters to the common
  functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()).
  Since these wrapper functions call __tx_port_find(), __tx_port_find() was
  moved from the common code back into sunvnet.c. Note - ldmvsw.c does not
  require this function.

  These changes also required that port_is_up() be made
  into a common function and thus it was given a _common suffix and
  exported like the other common functions.

  A wrapper function was also added for vnet_start_xmit_common() to pass a
  driver-specific function arg to return the port associated with a given
  struct sk_buff and struct net_device. This was required because
  vnet_start_xmit_common() grabs a lock prior to getting the associated
  port. Using a function pointer arg allowed the code to work unchanged
  without risking changes to the non-trivial locking logic in
  vnet_start_xmit_common().

31762eaa0d ldmvsw: Split sunvnet driver into common code
Split sunvnet.c into sunvnet.c and sunvnet_common.c.

  Details:

  Since the sunvnet and ldmvsw drivers will both use common sunvnet code,
  move the functions (and support functions) anticipated to be common code
  from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to
  sunvnet_common.h. The sunvnet_common.c code will be compiled into the
  kernel and act as a library of functions that are linked by either
  (or both) drivers when loaded.

  Function names for external functions in sunvnet_common.c (to be
  called by both the sunvnet and ldmvsw drivers) were tagged with a "_common"
  suffix to clearly designate them as common functions.

  No functional changes as of yet... just moved code verbatim to the new
  sunvnet_common.c/h files.

  Makefile/Kconfig support added to build sunvnet_common.c file. The code
  is included in the kernel if SUN_LDOMS is defined/selected.

  NOTE - per the SubmittingPatches documentation, since the code was just
  moved from one file another, the code was NOT checkpatch'd in this commit
  to aid in review.

fe3a5f6c79 openvswitch: allow output of MPLS packets on tunnel vports
Currently output of MPLS packets on tunnel vports is not allowed by Open
vSwitch. This is because historically encapsulation was done in such a way
that the inner_protocol field of the skb needed to hold the inner protocol
for both MPLS and tunnel encapsulation in order for GSO segmentation to be
performed correctly.

Since b2acd1dc39 ("openvswitch: Use regular GRE net_device instead of
vport") Open vSwitch makes use of lwt to output to tunnel netdevs which
perform encapsulation. As no drivers expose support for MPLS offloads this
means that GSO packets are segmented in software by validate_xmit_skb(),
which is called from __dev_queue_xmit(), before tunnel encapsulation occurs.
This means that the inner protocol of MPLS is no longer needed by the time
encapsulation occurs and the contention on the inner_protocol field of the
skb no longer occurs.

Thus it is now safe to output MPLS to tunnel vports.

snd_hdac_sync_audio_rate() call is mandatory only for HSW and later
models, but we call the function unconditionally blindly assuming that
the function doesn't do anything harmful.  But since recently, the
function checks the validity of the passed pin NID, and eventually
spews the warning if an unexpected pin is passed.  This is seen on old
chips like Baytrail.

The fix is to limit the call of this function again only for the chips
with the proper binding.  This can be identified by the same flag as
the eld notifier.

(busybox's cat uses sendfile(2), unlike the coreutils version)

This is because tracing_splice_read_pipe() can call splice_to_pipe()
with spd->nr_pages == 0.  spd_pages underflows in splice_to_pipe() and
we fill the page pointers and the other fields of the pipe_buffers with
garbage.

All other callers of splice_to_pipe() avoid calling it when nr_pages ==
0, and we could make tracing_splice_read_pipe() do that too, but it
seems reasonable to have splice_to_page() handle this condition
gracefully.

307d40c56b ARM: uniphier: rework SMP code to support new System Bus binding
During the review process of the UniPhier System Bus driver
(drivers/bus/uniphier.c), the current binding of the System Bus
Controller turned out to be no good.  In order to use the driver,
some nodes in the device trees must be tweaked.  It would also have
impacts on the SMP code because the SMP related registers are
located in the System Bus Controller block.  This commit reworks
the smp_operations to support the new binding, but still supports
the old binding, too.

55ff8cfbc4 USB: uas: Reduce can_queue to MAX_CMNDS
The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.

Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.

7222c83225 usb/core: usb_alloc_dev(): fix setting of ->portnum
With commit 69bec72598 ("USB: core: let USB device know device node"),
the port1 argument of usb_alloc_dev() gets overwritten as follows:

  ... usb_alloc_dev(..., unsigned port1)
  {
    ...
    if (!parent->parent) {
      port1 = usb_hcd_find_raw_port_number(..., port1);
    }
    ...
  }

Later on, this now overwritten port1 gets assigned to ->portnum:

  dev->portnum = port1;

However, since xhci_find_raw_port_number() isn't idempotent, the
aforementioned commit causes a number of KASAN splats like the following:

  BUG: KASAN: slab-out-of-bounds in xhci_find_raw_port_number+0x98/0x170

  [...]

Afterwards, xhci reports some functional errors:

  xhci_hcd 0000:00:14.0: ERROR: unexpected setup address command completion
                                code 0x11.

                                code 0x11.
  usb 4-3: device not accepting address 2, error -22

Fix this by not overwriting the port1 argument in usb_alloc_dev(), but
storing the raw port number as required by OF in an additional variable,
raw_port.

- removed DRV_VERSION
- defines: use defines instead of plain values,
  use BIT_ULL macro, add comments
- rename waitqueue return value to time_left
- sort local variables by length
- fix indentation and whitespace errors
- make function return void if the result is not used
  (octeon_i2c_stop, octeon_i2c_set_clock)
- remove debug code from octeon_i2c_stop
- renamed some functions for readability
- update copyright

691be973c0 ALSA: hda - Really restrict i915 notifier to HSW+
The commit [b62232d429: ALSA: hda - Limit i915 HDMI binding only for
HSW and later] tried to limit the usage of i915 audio notifier to the
recent Intel models and switch to the old method on pre-Haswell
models.  However, it assumed that the i915 component binding hasn't
been done on such models, and the assumption was wrong: namely,
Baytrail had already the i915 component binding due to powerwell
control.  Thus, the workaround wasn't applied to Baytrail.

For fixing this properly, this patch introduces a new flag indicating
the usage of audio notifier and codec_has_acomp() refers to this flag
instead of checking the existence of audio component.

Extend the tryacpi module parameter to turn off acpi_ipmi_probe such
that hard-coded options (type, ports, address, etc.) have complete

d9dffd2a0b ipmi_si: Avoid a wrong long timeout on transaction done
Under some circumstances, the IPMI state machine could return
a call without delay option but the driver would still do a long
delay because the result wasn't checked.  Instead of calling
the state machine after transaction done, just go back to the
top of the processing to start over.

a69fe1a2c9 ARC: build: Turn off -Wmaybe-uninitialized for ARC gcc 4.8
linux-next has been reporting gazillion warnings for ARC build and
I finally decided to take a bite:

http://kisskb.ellerman.id.au/kisskb/buildresult/12638735/

Most of the them are due to -Wmaybe-uninitialized

| ../kernel/sysctl.c: In function '__do_proc_doulongvec_minmax':
| ../kernel/sysctl.c:1928:12: warning: 'p' may be used uninitialized in this function [-Wmaybe-uninitialized]
|   ret = tmp - *buf;
|            ^
| ../kernel/sysctl.c:2342:29: note: 'p' was declared here
|  char *kbuf = NULL, *p;
|                     ^
| ...
| ...

Cursory look at code seemed fine and a definite gcc false positive in say
kernel/sysctl.c

Mystery was why only for ARC (and not with ARM linaro toolchain based
off same gcc 4.8). Turns out that -O3 (default for ARC) triggers these
and if I enable -O3 for ARM kernel build, I see the same splat.

I initially wanted to disable this only for gcc 4.8, but Arnd reported
it is seen even on gcc 6.0 for ARM with -O3. Thus better to disable
this independent of gcc version.

64e5cd7231 mmc: sdhci-of-at91: fix wake-up issue when using runtime pm
It is impossible to wake-up on card detect event because when sdhci
controller is runtime suspended, it is assumed that all clocks are
disabled so we can't get irqs.
If the device is removable and there is no gpio to manage the card
detection then polling is used. It doesn't mean card detection is broken.
It is curently we only way to wake-up on card event if using runtime pm.

bd9ff18bff mmc: sdhci-pci: Do not set DMA mask in enable_dma()
DMA mask will already be set by sdhci_set_dma_mask(), which
is equivalent to the removed code since pci_set_dma_mask()
expands to its DMA-API counterpart.

There should also be no reason to set the DMA mask after probe.

741b48f4f3 mmc: sdhci-acpi: Remove enable_dma() hook
This hook was solely used to set the DMA mask, which is now done
by the newly-added sdhci_set_dma_mask() function.

The use of a flag to ensure the mask is only set once is a strong hint
that it should not have been done there anyway.

Set the DMA mask in sdhci_add_host() after we determined the
capabilities of the device. 64-bit devices in particular are given the
proper mask that ensures bounce buffers are not used.

Also disable DMA if no proper DMA mask can be set, as the DMA-API

Here is the big staging driver pull request for 4.6-rc1.
 
 Lots of little things here, over 1600 patches or so.  Notible is all of
 the good Lustre work happening, those developers have finally woken up
 and are cleaning up their code greatly.  The Outreachy intern
 application process is also happening, which brought in another 400 or
 so patches.  Full details are in the very long shortlog.
 
 All of these have been in linux-next with no reported issues.

 "The most notable item is addition of support for Synaptics RMI4
  protocol which is native protocol for all current Synaptics devices
  (touchscreens, touchpads).  In later releases we'll switch devices
  using HID and PS/2 protocol emulation to RMI4.

  You will also get:
   - BYD PS/2 touchpad protocol support for psmouse
   - MELFAS MIP4 Touchscreen driver
   - rotary encoder was moved away from legacy platform data and to
     generic device properties API, devm_* API, and can now handle
     encoders using more than 2 GPIOs
   - Cypress touchpad driver was switched to devm_* API and device
     properties
   - other assorted driver fixes"
