16baeb307b powerpc/4xx: Fix warning in kilauea.dtb
Currently I see:
  DTC     arch/powerpc/boot/kilauea.dtb
Warning (reg_format): "reg" property in /plb/ppc4xx-msi@C10000000 has invalid length (12 bytes) (#address-cells == 1, #size-cells == 1)

It appears that unlike the other platforms handled by 3fb7933850
"powerpc/4xx: Adding PCIe MSI support" this platform does not use address-cells=2.

3868204d6b {pktgen, xfrm} Update IPv4 header total len and checksum after tranformation
commit a553e4a631 ("[PKTGEN]: IPSEC support")
tried to support IPsec ESP transport transformation for pktgen, but acctually
this doesn't work at all for two reasons(The orignal transformed packet has
bad IPv4 checksum value, as well as wrong auth value, reported by wireshark)

- After transpormation, IPv4 header total length needs update,
  because encrypted payload's length is NOT same as that of plain text.

- After transformation, IPv4 checksum needs re-caculate because of payload
  has been changed.

With this patch, armmed pktgen with below cofiguration, Wireshark is able to
decrypted ESP packet generated by pktgen without any IPv4 checksum error or
auth value error.

8fc3b9e9a2 virtio_net: fix error handling for mergeable buffers
Eric Dumazet noticed that if we encounter an error
when processing a mergeable buffer, we don't
dequeue all of the buffers from this packet,
the result is almost sure to be loss of networking.

Jason Wang noticed that we also leak a page and that we don't decrement
the rq buf count, so we won't repost buffers (a resource leak).

Fix both issues.

d36240d260 power_supply: Add power_supply notifier
This patch adds a notifier chain to the power_supply, this helps drivers
in other subsystem to listen to changes in power supply subsystem.

This would help to take some actions in those drivers on changing the
power supply properties. One such scenario is to increase/decrease system
performance based on the battery capacity/voltage. Another scenario is to
adjust the h/w peak current detection voltage/current thresholds based on
battery voltage/capacity. The notifier helps drivers to listen to changes
in power_suppy susbystem without polling the power_supply properties

46ca506c43 ARM: kirkwood: Add support for NETGEAR ReadyNAS NV+ v2
Almost all hardware parts of the NETGEAR ReadyNAS NV+ v2 ([1] for more
details) are supported by mainline kernel. The only missing elements in
provided .dts file are:

 - the front LCD module (Winstar WINSTAR WH1602): driver development is
   ongoing. This is the same LCD module as on ReadyNAS 104.
 - the Macronix MX25L512 512Kbit SPI flash: no time to play with it yet.

The device is the big brother (4 vs 2 bay) of the ReadyNAS Duo v2. The
main differences are some additional LEDs for the disks, a Marvell
88SM4140 SATA Port multiplier (no driver required to access the disk)
and previously described LCD module. Otherwise, it shares the same SoC
(kirkwood 88F6282), RAM (256MB), NAND (128MB), RTC chip (Ricoh rs5c372a),
fan controller (GMT G762), XHCI controller (NEC/Renesas µPD720200).

80c6463e2f power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activate
power_supply_register() calls device_init_wakeup() to register a wakeup
source before initializing dev_name. As a result, device_wakeup_enable()
end up registering wakeup source with a null name when
wakeup_source_register() gets called with dev_name(dev) which is null at
the time.

When kernel is booted with wakeup_source_activate enabled, it will panic
when the trace point code tries to dereference ws->name.

Fixed the problem by moving up the kobject_set_name() call prior to
accesses to dev_name(). Replaced kobject_set_name() with dev_set_name()
which is the right interface to be called from drivers. Fixed the call to
device_del() prior to device_add() in for wakeup_init_failed error
handling code.

Trace after the change:

88bf6d62db [SCSI] hpsa: return 0 from driver probe function on success, not 1
A return value of 1 is interpreted as an error.  See pci_driver.
in local_pci_probe().  If you're wondering how this ever could
have worked, it's because it used to be the case that only return
values less than zero were interpreted as failure.  But even in
the current kernel if the driver registers its various entry
points with the kernel, and then returns a value which is
interpreted as failure, those registrations aren't undone, so
the driver still mostly works.  However, the driver's remove
function wouldn't be called on rmmod, and pci power management
functions wouldn't work.  In the case of Smart Array, since it
has a battery backed cache (or else no cache) even if the driver
is not shut down properly as long as there is no outstanding
i/o, nothing too bad happens, which is why it took so long to
notice.

Requesting backport to stable because the change to pci-driver.c
which requires driver probe functions to return 0 occurred between
2.6.35 and 2.6.36 (the pci power management breakage) and again
between 3.7 and 3.8 (pci_dev->driver getting set to NULL in
local_pci_probe() preventing driver remove function from being
called on rmmod.)

11d4bb1bd0 ARM: 7907/1: lib: delay-loop: Add align directive to fix BogoMIPS calculation
Currently mx53 (CortexA8) running at 1GHz reports:
Calibrating delay loop... 663.55 BogoMIPS (lpj=3317760)

Tom Evans verified that alignments of 0x0 and 0x8 run the two instructions of __loop_delay in one clock cycle (1 clock/loop), while alignments of 0x4 and 0xc take 3 clocks to run the loop twice. (1.5 clock/loop)

The original object code looks like this:

00000010 <__loop_const_udelay>:
  10:	e3e01000 	mvn	r1, #0
  14:	e51f201c 	ldr	r2, [pc, #-28]	; 0 <__loop_udelay-0x8>

  40:	8afffffe 	bhi	3c <__loop_delay>
  44:	e1a0f00e 	mov	pc, lr

After adding the 'align 3' directive to __loop_delay (align to 8 bytes):

00000010 <__loop_const_udelay>:
  10:	e3e01000 	mvn	r1, #0
  14:	e51f201c 	ldr	r2, [pc, #-28]	; 0 <__loop_udelay-0x8>

  48:	e1a0f00e 	mov	pc, lr
  4c:	e320f000 	nop	{0}

, which now reports:
Calibrating delay loop... 996.14 BogoMIPS (lpj=4980736)

Some more test results:

On mx31 (ARM1136) running at 532 MHz, before the patch:
Calibrating delay loop... 351.43 BogoMIPS (lpj=1757184)

On mx31 (ARM1136) running at 532 MHz after the patch:
Calibrating delay loop... 528.79 BogoMIPS (lpj=2643968)

Also tested on mx6 (CortexA9) and on mx27 (ARM926), which shows the same
BogoMIPS value before and after this patch.

Copying a function with memcpy() and then trying to execute the
result isn't trivially portable to Thumb.

This patch modifies the kexec soft restart code to copy its
assembler trampoline relocate_new_kernel() using fncpy() instead,
so that relocate_new_kernel can be in the same ISA as the rest of
the kernel without problems.

After "ARM: signal: sigreturn_codes should be endian neutral to
work in BE8" commit, thumb only platforms, like armv7m, fails to
compile sigreturn_codes.S. The reason is that for such arch
values '.arm' directive and arm opcodes are not allowed.

Fix conditionally enables arm opcodes only if no CONFIG_CPU_THUMBONLY
defined and it uses .org instructions to keep sigreturn_codes
layout.

161bd3bf60 parisc: fix kernel memory layout in vmlinux.ld.S
When building a 64bit kernel sometimes functions in the .init section were not
able to reach the standard kernel function. Main reason for this problem is,
that the linkage tables (.plt, .opd, .dlt) tend to become pretty huge and thus
the distance gets too big for short calls.

One option to avoid this is to use the -mlong-calls compiler option, but this
increases the binary size and introduces a performance penalty.

Instead, with this patch we just lay out the binary differently.  Init code is
stored first, followed by text, R/O and finally R/W data. This means, that init
and text code is now much closer to each other, which is sufficient to reach
each other by short calls.

0576da2c08 parisc: fix mmap(MAP_FIXED|MAP_SHARED) to already mmapped address
locale-gen on Debian showed a strange problem on parisc:
mmap2(NULL, 536870912, PROT_NONE, MAP_SHARED, 3, 0) = 0x42a54000
mmap2(0x42a54000, 103860, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 3, 0) = -1 EINVAL (Invalid argument)

Basically it was just trying to re-mmap() a file at the same address
which it was given by a previous mmap() call. But this remapping failed
with EINVAL.

The problem is, that when MAP_FIXED and MAP_SHARED flags were used, we didn't
included the mapping-based offset when we verified the alignment of the given
fixed address against the offset which we calculated it in the previous call.
