adf96e6f51 sysrq: don't depend on weak undefined arrays to have an address that compares as NULL
When taking an address of an extern array, gcc quite naturally should be
able to say "an address of an object can never be NULL" and just
optimize away the test entirely.

However, the new alternate sysrq reset code (commit 154b7a489a:
"Input: sysrq - allow specifying alternate reset sequence") did exactly
that, and declared platform_sysrq_reset_seq[] as a weak array, and
expecting that testing the address of the array would show whether it
actually got linked against something or not.

And that doesn't work with all gcc versions.  Clearly it works with
*some* versions of gcc, and maybe it's even supposed to work, but it
really is a very fragile concept.

So instead of testing the address of the weak variable, just create a
weak instance of that array that is empty.  If some platform then has a
real platform_sysrq_reset_seq[] that overrides our weak one, the linker
will switch to that one, and it all works without any run-time
conditionals at all.

f00b4dad9d dma-buf: implement vmap refcounting in the interface logic
All drivers which implement this need to have some sort of refcount to
allow concurrent vmap usage. Hence implement this in the dma-buf core.

To protect against concurrent calls we need a lock, which potentially
causes new funny locking inversions. But this shouldn't be a problem
for exporters with statically allocated backing storage, and more
dynamic drivers have decent issues already anyway.

Inspired by some refactoring patches from Aaron Plattner, who
implemented the same idea, but only for drm/prime drivers.

v2: Check in dma_buf_release that no dangling vmaps are left.
Suggested by Aaron Plattner. We might want to do similar checks for
attachments, but that's for another patch. Also fix up ERR_PTR return
for vmap.

v3: Check whether the passed-in vmap address matches with the cached
one for vunmap. Eventually we might want to remove that parameter -
compared to the kmap functions there's no need for the vaddr for
unmapping.  Suggested by Chris Wilson.

v4: Fix a brown-paper-bag bug spotted by Aaron Plattner.

1b83bef24c libceph: update osd request/reply encoding
Use the new version of the encoding for osd requests and replies.  In the
process, update the way we are tracking request ops and reply lengths and
results in the struct ceph_osd_request.  Update the rbd and fs/ceph users
appropriately.

The main changes are:
 - we keep pointers into the request memory for fields we need to update
   each time the request is sent out over the wire
 - we keep information about the result in an array in the request struct
   where the users can easily get at it.

c47f937154 rbd: pass length, not op for osd completions
The only thing type-specific osd completion functions do with their
osd op parameter is (in some cases) extract the number of bytes
transferred from it.  In the other cases, the xferred bytes field
is not used, and total message data transfer byte count (which may
well be zero) is used.

Just set the object request transfer count in the main osd request
callback function and provide that to the other routines.  There is
then no longer any need to pass the op pointer to the type-specific
completion routines, so drop those parameters.

Stop doing anything with the total message data length.

  At this point there is one patch series left outstanding from Asias to
  add support for UNMAP + WRITE_SAME w/ UNMAP=1 to FILEIO awaiting

3eb05225ee pwm: Changes for v3.9-rc1
A new driver has been added to support the PWM mode of the timer counter
 blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing
 the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained
 suspend and resume functionality.
 
 User drivers can now query the core for whether access to a PWM device
 will sleep (if the PWM chip is on a slow bus such as I2C or SPI).
 
 The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state
 in addition to the FB layer's blanking states.
 
 To round things off, a few fixes and cleanups are also included.

    capability to be turned on.  It increases write throughput by 20%+,
    but may also increase average write latency; more testing needed.)
  - Add DT bindings for capability flags.
  - Add mmc_of_parse() for shared DT parsing between drivers.
 
 Drivers:
  - android-goldfish: New MMC driver for the Android Goldfish emulator.
  - mvsdio: Add DT bindings, pinctrl, use slot-gpio for card detection.
  - omap_hsmmc: Fix boot hangs with RPMB partitions.
  - sdhci-bcm2835: New driver for controller used by Raspberry Pi.

cc344fa1b5 rbd: eliminate sparse warnings
Fengguang Wu reminded me that there were outstanding sparse reports
in the ceph and rbd code.  This patch fixes these problems in rbd
that lead to those reports:
    - Convert functions that are never referenced externally to have
      static scope.
    - Add a lockdep annotation to rbd_request_fn(), because it
      releases a lock before acquiring it again.

632b88cade rbd: barriers are hard
Let's go shopping!

I'm afraid this may not have gotten it right:
    07741308  rbd: add barriers near done flag operations

The smp_wmb() should have been done *before* setting the done flag,
to ensure all other data was valid before marking the object request
done.

Switch to use atomic_inc_return() here to set the done flag, which
allows us to verify we don't mark something done more than once.
Doing this also implies general barriers before and after the call.

And although a read memory barrier might have been sufficient before
reading the done flag, convert this to a full memory barrier just
to put this issue to bed.

565d956a7e ACPI: Overriding ACPI tables via initrd only works with an initrd and on X86
Reflect this dependency in Kconfig, to prevent build failures.

Shorten the config description as suggested by Borislav Petkov.

Finding a suitable memory area to store the modified table(s) has been
taken over from arch/x86/kernel/setup.c and makes use of max_low_pfn_mapped:
memblock_find_in_range(0, max_low_pfn_mapped,...)
This one is X86 specific. It may not be hard to extend this functionality
for other ACPI aware architectures if there is need for.

For now make this feature only available for X86 to avoid build failures on
IA64, compare with:

f72dd56690 IPoIB: Free ipoib neigh on path record failure so path rec queries are retried
If IPoIB fails to look up a path record (eg if it tries during an SM
failover when one SM is dead but the new one hasn't taken over yet), the
driver ends up with a neighbour structure but no address handle (AH).
There's no mechanism to recover from this: any further packets sent to
this destination will be silently dumped in ipoib_start_xmit().

Fix this by freeing the neighbour structures when a path rec query
fails, so that the next packet queued to be sent will trigger a new path
record query.

2ce19e72f4 IB/srp: Fail I/O requests if the transport is offline
If an SRP target is no longer reachable and srp_reset_host() fails to
reconnect then ib_srp will invoke scsi_remove_host().  That function
will invoke __scsi_remove_device() for each LUN.  And that last
function will change the device state from SDEV_TRANSPORT_OFFLINE into
SDEV_CANCEL.  Certain user space software, e.g. older versions of
multipathd, continue queueing I/O to SCSI devices that are in the
SDEV_CANCEL state.

If these I/O requests are submitted as SG_IO that means that the
REQ_PREEMPT flag will be set and hence that these requests will be
passed to srp_queuecommand().  These requests will time out.  If new
requests are queued fast enough from user space these active requests
will prevent __scsi_remove_device() to finish.

Avoid this by failing I/O requests in the SDEV_CANCEL state if the
transport is offline.  Introduce a new variable to keep track of the
transport state instead of failing requests if (!target->connected ||
target->qp_in_error), so that the SCSI error handler has a chance to
retry commands after a transport layer failure occurred.

c7c4e7ff80 IB/srp: Avoid endless SCSI error handling loop
If a SCSI command times out it is passed to the SCSI error
handler. The SCSI error handler will try to abort the commands that
timed out.  If aborting fails, a device reset will be attempted.  If
the device reset also fails a host reset will be attempted.  If the
host reset also fails the whole procedure will be repeated.

srp_abort() and srp_reset_device() fail for a QP in the error state.
srp_reset_host() fails after host removal has started.  Hence if the
SCSI error handler gets invoked after host removal has started and
with the QP in the error state an endless loop will be triggered.

Modify the SCSI error handling functions in ib_srp as follows:
- Abort SCSI commands properly even if the QP is in the error state.
- Make srp_reset_host() reset SCSI requests even after host removal
  has already started or if reconnecting fails.

ab7826595e This is the MFD pull request for the 3.9 merge window.
No new drivers this time, but a bunch of fairly big cleanups:
 
 - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
   OMAP5 support and clock management code cleanup.
 
 - The first step of a major sync for the ab8500 driver from Lee Jones. In
   particular, the debugfs and the sysct interfaces got extended and improved.
 
 - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
   driver, with a much needed module id lookup code improvement.
 
 - The regular wm5102 and arizona cleanups and fixes from Mark Brown.
 
 - Laxman Dewangan extended the palmas APIs in order to implement the palmas
   GPIO and rt drivers.
 
 - Laxman also added DT support for the tps65090 driver.
 
 - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
   Darren Hart.
 
 - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
   devices to switch to the new abx500 pin-ctrl driver.
 
 - The max8925 now has device tree and irqdomain support thanks to Qing Xu.
 
 - The recently added rtsx driver got a few cleanups and fixes for a better
   card detection code path and now also supports the RTS5227 chipset, thanks
   to Wei Wang and Roger Tseng.

a883b70d8e tty vt: fix character insertion overflow
Commit 81732c3b2f ("tty vt: Fix line garbage in virtual console on
command line edition") broke insert_char() in multiple ways.  Then
commit b1a925f44a ("tty vt: Fix a regression in command line edition")
partially fixed it.  However, the buffer being moved is still too large
and overflowing beyond the end of the current line, corrupting existing
characters on the next line.

Example test case:

echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B"

Expected result:

ab c
de

Current result:

ab c
 e

Needless to say that this is very annoying when inserting words in the
middle of paragraphs with certain text editors.

48412a7e7d vmxnet3: fix ethtool ring buffer size setting
Noticed that vmxnet3's get_ringparam function was returning the summation of all
ring buffers on a NIC, rather than just the size of any one ring.  This causes
problems when a vmxnet3 instance has multiple queues, as ethtool, when setting
ring parameters, first gets the current ring parameters to set the existing
values in the set_ringparm commannd.  The result is, that unless both rx and tx
ring sizes are set in a single operation, which ever ring is not set will
silently have its ring count multiplied by the number of queues on the NIC until
it reaches a driver defined maxiumum value.

Fix it by not multiplying the rx and tx ring sizes by the number of queues in
the system, like every other driver.  Tested by myself successfully.

Pull Xen update from Konrad Rzeszutek Wilk:
 "This has two new ACPI drivers for Xen - a physical CPU offline/online
  and a memory hotplug.  The way this works is that ACPI kicks the
  drivers and they make the appropiate hypercall to the hypervisor to
  tell it that there is a new CPU or memory.  There also some changes to
  the Xen ARM ABIs and couple of fixes.  One particularly nasty bug in
  the Xen PV spinlock code was fixed by Stefan Bader - and has been
  there since the 2.6.32!

  Features:
   - Xen ACPI memory and CPU hotplug drivers - allowing Xen hypervisor
     to be aware of new CPU and new DIMMs
   - Cleanups
  Bug-fixes:
   - Fixes a long-standing bug in the PV spinlock wherein we did not
     kick VCPUs that were in a tight loop.
   - Fixes in the error paths for the event channel machinery"
