cpu topology: remove stale arch_provides_topology_pointers and define_siblings_show_map/list()
arch_provides_topology_pointers was introduced in commit
23ca4bba3 (x86:
cleanup early per cpu variables/accesses v4) to indicate pointers to the
topology cpumask_t maps are valid to avoid copying data on to/off of the
stack.
But later in commit
fbd59a8d (cpumask: Use topology_core_cpumask()/
topology_thread_cpumask()), the pointers to the topology struct cpumask maps
are always valid.
After that commit, the only difference is that there is a redundant
"unsigned int cpu = dev->id;" if arch_provides_topology_pointers defined, but
dev->id is type 'u32' which devolves to 'unsigned int' on all supported arches.
So this arch_provides_topology_pointers define is pointless and only cause
obfuscation now, remove it.
Tested on x86 machine, topology information in sys/devices/system/cpu/
cpuX/topology/ is the same after appling this patch set.

Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"
We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8. That problem is tracked by the bug entry at:
https://bugzilla.kernel.org/show_bug.cgi?id=51231
Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.
For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

mfd: max8925: fix dt code for backlight
The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.
I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.
This silences the warning:

drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]
Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

kobject: delayed kobject release: help find buggy drivers
Implement debugging for kobject release functions. kobjects are
reference counted, so the drop of the last reference to them is not
predictable. However, the common case is for the last reference to be
the kobject's removal from a subsystem, which results in the release
function being immediately called.
This can hide subtle bugs, which can occur when another thread holds a
reference to the kobject at the same time that a kobject is removed.
This results in the release method being delayed.
In order to make these kinds of problems more visible, the following
patch implements a delayed release; this has the effect that the
release function will be out of order with respect to the removal of
the kobject in the same manner that it would be if a reference was
being held.
This provides us with an easy way to allow driver writers to debug
their drivers and fix otherwise hidden problems.

xfs: di_flushiter considered harmful
When we made all inode updates transactional, we no longer needed
the log recovery detection for inodes being newer on disk than the
transaction being replayed - it was redundant as replay of the log
would always result in the latest version of the inode would be on
disk. It was redundant, but left in place because it wasn't
considered to be a problem.
However, with the new "don't read inodes on create" optimisation,
flushiter has come back to bite us. Essentially, the optimisation
made always initialises flushiter to zero in the create transaction,
and so if we then crash and run recovery and the inode already on
disk has a non-zero flushiter it will skip recovery of that inode.
As a result, log recovery does the wrong thing and we end up with a
corrupt filesystem.
Because we have to support old kernel to new kernel upgrades, we
can't just get rid of the flushiter support in log recovery as we
might be upgrading from a kernel that doesn't have fully transactional
inode updates. Unfortunately, for v4 superblocks there is no way to
guarantee that log recovery knows about this fact.
We cannot add a new inode format flag to say it's a "special inode
create" because it won't be understood by older kernels and so
recovery could do the wrong thing on downgrade. We cannot specially
detect the combination of zero mode/non-zero flushiter on disk to
non-zero mode, zero flushiter in the log item during recovery
because wrapping of the flushiter can result in false detection.
Hence that makes this "don't use flushiter" optimisation limited to
a disk format that guarantees that we don't need it. And that means
the only fix here is to limit the "no read IO on create"
optimisation to version 5 superblocks....

usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0
Xhci controllers with hci_version > 0.96 gives spurious success
events on short packet completion. During webcam capture the
"ERROR Transfer event TRB DMA ptr not part of current TD" was observed.
The same application works fine with synopsis controllers hci_version 0.96.
The same issue is seen with Intel Pantherpoint xhci controller. So enabling
this quirk in xhci_gen_setup if controller verion is greater than 0.96.
For xhci-pci move the quirk to much generic place xhci_gen_setup.
Note from Sarah:
The xHCI 1.0 spec changed how hardware handles short packets. The HW
will notify SW of the TRB where the short packet occurred, and it will
also give a successful status for the last TRB in a TD (the one with the
IOC flag set). On the second successful status, that warning will be
triggered in the driver.
Software is now supposed to not assume the TD is not completed until it
gets that last successful status. That means we have a slight race
condition, although it should have little practical impact. This patch
papers over that issue.
It's on my long-term to-do list to fix this race condition, but it is a
much more involved patch that will probably be too big for stable. This
patch is needed for stable to avoid serious log spam.
This patch should be backported to kernels as old as 3.0, that

The patch will have to be modified for kernels older than 3.2, since
that kernel added the xhci_gen_setup function for xhci platform devices.

These functions are not always used, and since they're marked static
they will produce build warnings:
- xhci_msix_sync_irqs is only used with CONFIG_PCI.
- xhci_change_max_exit_latency is a little more complicated with

xhci: Avoid NULL pointer deref when host dies.
When the host controller fails to respond to an Enable Slot command, and
the host fails to respond to the register write to abort the command
ring, the xHCI driver will assume the host is dead, and call
usb_hc_died().
The USB device's slot_id is still set to zero, and the pointer stored at
xhci->devs[0] will always be NULL. The call to xhci_check_args in
xhci_free_dev should have caught the NULL virt_dev pointer.
However, xhci_free_dev is designed to free the xhci_virt_device
structures, even if the host is dead, so that we don't leak kernel
memory. xhci_free_dev checks the return value from the generic
xhci_check_args function. If the return value is -ENODEV, it carries on
trying to free the virtual device.
The issue is that xhci_check_args looks at the host controller state
before it looks at the xhci_virt_device pointer. It will return -ENIVAL
because the host is dead, and xhci_free_dev will ignore the return
value, and happily dereference the NULL xhci_virt_device pointer.
The fix is to make sure that xhci_check_args checks the xhci_virt_device
pointer before it checks the host state.
See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for
further details. This patch doesn't solve the underlying issue, but
will ensure we don't see any more NULL pointer dereferences because of
the issue.
This patch should be backported to kernels as old as 3.1, that
contain the commit
7bd89b4017f46a9b92853940fd9771319acb578a "xhci: Don't

md/raid5: fix interaction of 'replace' and 'recovery'.
If a device in a RAID4/5/6 is being replaced while another is being
recovered, then the writes to the replacement device currently don't
happen, resulting in corruption when the replacement completes and the
new drive takes over.
This is because the replacement writes are only triggered when
's.replacing' is set and not when the similar 's.sync' is set (which
is the case during resync and recovery - it means all devices need to
be read).
So schedule those writes when s.replacing is set as well.
In this case we cannot use "STRIPE_INSYNC" to record that the
replacement has happened as that is needed for recording that any
parity calculation is complete. So introduce STRIPE_REPLACED to
record if the replacement has happened.
For safety we should also check that STRIPE_COMPUTE_RUN is not set.
This has a similar effect to the "s.locked == 0" test. The latter
ensure that now IO has been flagged but not started. The former
checks if any parity calculation has been flagged by not started.
We must wait for both of these to complete before triggering the
'replace'.
Add a similar test to the subsequent check for "are we finished yet".
This possibly isn't needed (is subsumed in the STRIPE_INSYNC test),
but it makes it more obvious that the REPLACE will happen before we
think we are finished.
Finally if a NeedReplace device is not UPTODATE then that is an
error. We really must trigger a warning.
This bug was introduced in commit
9a3e1101b827a59ac9036a672f5fa8d5279d0fe2
(md/raid5: detect and handle replacements during recovery.)
which introduced replacement for raid5.
That was in 3.3-rc3, so any stable kernel since then would benefit
from this fix.

ftrace: Add check for NULL regs if ops has SAVE_REGS set
If a ftrace ops is registered with the SAVE_REGS flag set, and there's
already a ops registered to one of its functions but without the
SAVE_REGS flag, there's a small race window where the SAVE_REGS ops gets
added to the list of callbacks to call for that function before the
callback trampoline gets set to save the regs.
The problem is, the function is not currently saving regs, which opens
a small race window where the ops that is expecting regs to be passed
to it, wont. This can cause a crash if the callback were to reference
the regs, as the SAVE_REGS guarantees that regs will be set.
To fix this, we add a check in the loop case where it checks if the ops
