286e4f90a7 powerpc: Align p_end
p_end is an 8 byte value embedded in the text section. This means it
is only 4 byte aligned when it should be 8 byte aligned. Fix this
by adding an explicit alignment.

This fixes an issue where POWER7 little endian builds with
CONFIG_RELOCATABLE=y fail to boot.

ca1de5deb7 powernv/eeh: Add buffer for P7IOC hub error data
Prevent ioda_eeh_hub_diag() from clobbering itself when called by supplying
a per-PHB buffer for P7IOC hub diagnostic data.  Take care to inform OPAL of
the correct size for the buffer.

20151169f1 powerpc: Make 64-bit non-VMX __copy_tofrom_user bi-endian
The powerpc 64-bit __copy_tofrom_user() function uses shifts to handle
unaligned invocations.  However, these shifts were designed for
big-endian systems: On little-endian systems, they must shift in the
opposite direction.

This commit relies on the C preprocessor to insert the correct shifts
into the assembly code.

[ This is a rare but nasty LE issue. Most of the time we use the POWER7
optimised __copy_tofrom_user_power7 loop, but when it hits an exception
we fall back to the base __copy_tofrom_user loop. - Anton ]

90ff5d688e powerpc: Fix bad stack check in exception entry
In EXCEPTION_PROLOG_COMMON() we check to see if the stack pointer (r1)
is valid when coming from the kernel.  If it's not valid, we die but
with a nice oops message.

Currently we allocate a stack frame (subtract INT_FRAME_SIZE) before we
check to see if the stack pointer is negative.  Unfortunately, this
won't detect a bad stack where r1 is less than INT_FRAME_SIZE.

This patch fixes the check to compare the modified r1 with
-INT_FRAME_SIZE.  With this, bad kernel stack pointers (including NULL
pointers) are correctly detected again.

Kudos to Paulus for finding this.

f084280cd3 PCI / ACPI: Install wakeup notify handlers for all PCI devs with ACPI
It turns out that some BIOSes don't report wakeup GPEs through
_PRW, but use them for signaling wakeup anyway, which causes GPE
storms to occur on some systems after resume from system suspend.
This issue has been uncovered by commit d2e5f0c16a (ACPI / PCI:
Rework the setup and cleanup of device wakeup) during the 3.9
development cycle.

Work around the problem by installing wakeup notify handlers for all
PCI devices with ACPI support (i.e. having ACPI companions) regardless
of whether or not the BIOS reports ACPI wakeup support for them.  The
presence of the wakeup notify handlers alone is not harmful in any
way if there are no events for them to handle (they are simply never
executed then), but on some systems they are needed to take care of
spurious events.

Fixes: d2e5f0c16a (ACPI / PCI: Rework the setup and cleanup of device wakeup)

72368d122c cpufreq: Clean up after a failing light-weight initialization
If cpufreq_policy_restore() returns NULL during system resume,
__cpufreq_add_dev() should just fall back to the full initialization
instead of returning an error, because that may actually make things
work.  Moreover, it should not leave stale fallback data behind after
it has failed to restore a previously existing policy.

This change is based on Viresh Kumar's work.

Netfilter/IPVS fixes for net

This patchset contains four nf_tables fixes, one IPVS fix due to
missing updates in the interaction with the new sedadj conntrack
extension that was added to support the netfilter synproxy code,
and a couple of one-liners to fix netnamespace netfilter issues.
More specifically, they are:

* Fix ipv6_find_hdr() call without offset being explicitly initialized
  in nft_exthdr, as required by that function, from Daniel Borkmann.

* Fix oops in nfnetlink_log when using netns and unloading the kernel
  module, from Gao feng.

* Fix BUG_ON in nf_ct_timestamp extension after netns is destroyed,
  from Helmut Schaa.

* Fix crash in IPVS due to missing sequence adjustment extension being
  allocated in the conntrack, from Jesper Dangaard Brouer.

* Add bugtrap to spot a warning in case you deference sequence adjustment
  conntrack area when not available, this should help to catch similar
  invalid dereferences in the Netfilter tree, also from Jesper.

* Fix incomplete dumping of sets in nf_tables when retrieving by family,
  from me.

* Fix oops when updating the table state (dormant <-> active) and having
  user (not base ) chains, from me.

* Fix wrong validation in set element data that results in returning
  -EINVAL when using the nf_tables dictionary feature with mappings,
  also from me.

We don't usually have this amount of fixes by this time (as we're already
in -rc5 of the development cycle), although half of them are related to
nf_tables which is a relatively new thing, and I also believe that holidays
have also delayed the flight of bugfixes to mainstream a bit.

Second Round of Renesas ARM based SoC Fixes for v3.13

* r8a7790 (R-Car H2) based Lager board
  - Correct SHDI resource sizes
    This bug has been present since sdhi resources were added to the r8a7790 by
    8c9b1aa418 ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
    templates") in v3.11-rc2.

* r8a7778 (R-Car M1) based Bock-W board
  - Correct DMA mask
    This resolves a regression introduced by 4dcfa60071
    ("ARM: DMA-API: better handing of DMA masks for coherent allocations")
    in v3.12-rc1.

* r8a7740 (R-Mobile A1) based Armadillo board
  - Add PWM backlight power supply
    This resolves a regression introduced by 22ceeee16e
    ("pwm-backlight: Add power supply support") in v3.12.

9928422fef ARM: pxa: fix USB gadget driver compilation regression
After commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1e
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.

However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:

This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.

Before commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.

Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

The DT nodes should look like

55883fd104 batman-adv: clean nf state when removing protocol header
If an interface enslaved into batman-adv is a bridge (or a
virtual interface built on top of a bridge) the nf_bridge
member of the skbs reaching the soft-interface is filled
with the state about "netfilter bridge" operations.

Then, if one of such skbs is locally delivered, the nf_bridge
member should be cleaned up to avoid that the old state
could mess up with other "netfilter bridge" operations when
entering a second bridge.
This is needed because batman-adv is an encapsulation
protocol.

However at the moment skb->nf_bridge is not released at all
leading to bogus "netfilter bridge" behaviours.

Fix this by cleaning the netfilter state of the skb before
it gets delivered to the upper layer in interface_rx().

750b8de6c4 cifs: We do not drop reference to tlink in CIFSCheckMFSymlink()
When we obtain tcon from cifs_sb, we use cifs_sb_tlink() to first obtain
tlink which also grabs a reference to it. We do not drop this reference
to tlink once we are done with the call.

The patch fixes this issue by instead passing tcon as a parameter and
avoids having to obtain a reference to the tlink. A lookup for the tcon
is already made in the calling functions and this way we avoid having to
re-run the lookup. This is also consistent with the argument list for
other similar calls for M-F symlinks.

We should also return an ENOSYS when we do not find a protocol specific
function to lookup the MF Symlink data.

1a29321ed0 net_sched: act: Dont increment refcnt on replace
This is a bug fix. The existing code tries to kill many
 birds with one stone: Handling binding of actions to
 filters, new actions and replacing of action
 attributes. A simple test case to illustrate:

XXXX
 moja@fe1:~$ sudo tc actions add action drop index 12
 moja@fe1:~$ actions get action gact index 12
 action order 1: gact action drop
  random type none pass val 0
  index 12 ref 1 bind 0
 moja@fe1:~$ sudo tc actions replace action ok index 12
 moja@fe1:~$ actions get action gact index 12
 action order 1: gact action drop
  random type none pass val 0
  index 12 ref 2 bind 0
XXXX

The above shows the refcounf being wrongly incremented on replace.
There are more complex scenarios with binding of actions to filters
that i am leaving out that didnt work as well...

7e367c18c0 ARM: OMAP2+: Fix LCD panel backlight regression for LDP legacy booting
Looks like the LCD panel on LDP has been broken quite a while, and
recently got fixed by commit 0b2aa8bed3 (gpio: twl4030: Fix regression
for twl gpio output). However, there's still an issue left where the panel
backlight does not come on if the LCD drivers are built into the
kernel.

Fix the issue by registering the DPI LCD panel only after the twl4030
GPIO has probed.
