Commit ac3d5ac27735 ("xen-netback: fix guest-receive-side array sizes")
added calls to vmalloc and vfree in the interface.c file without including
<linux/vmalloc.h>. This causes build failures if the
-Werror=implicit-function-declaration flag is passed.

In function lowpan_header_create(), we invoke the following code
construct:
struct ipv6hdr *hdr;
...
hdr = ipv6_hdr(skb);
...
if (...)
memcpy(hc06_ptr + 1, &hdr->flow_lbl[1], 2);
else
memcpy(hc06_ptr, &hdr, 4);
Where the else path of the condition, that is, non-compression
path, calls memcpy() with a pointer to struct ipv6hdr *hdr as
source, thus two levels of indirection. This cannot be correct,
and likely only one level of pointer was intended as source
buffer for memcpy() here.

If the hypervisor configures a vlan for the VF via the PF, the expected
result is that only packets tagged by said vlan will be received by the VF
(and that vlan will be silently removed).
Due to an incorrect manipulation of vlan filters in the driver, the
VF can receive untagged traffic even if the hypervisor configured
some vlan for it.
This patch corrects the behaviour.

There are 2 different (related) flows in the slowpath configuration
that utilize the same pointer and cast it to different structs;
This is obviously incorrect as the intended allocated memory is that
of the smaller struct, possibly causing the flow utilizing the larger
struct to corrupt other slowpath configuration.
Since both flows are exclusive, set the allocated memory to be a union
of both structs.

With kernel 3.13rc5 there are no AC adapter notifications on my laptop.
Commit cc8ef5270734 "ACPI / AC: convert ACPI ac driver to platform bus"
changed the driver to listen to device notifications only. However, AML
code on my laptop notifies the driver with zero event.
This patch changes the driver to listen to all events again.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.14
Not a lot going on framework wise, partly due to Christmas at least in
the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:
- Update to the generic DMA code to support deferred probe and managed
resources.
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs.
- Device tree support for the simple card, max98090 and cs42l52.
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi.
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi.

This reverts commit 145e1c0023585e0e8f6df22316308ec61c5066b2.
This commit broke the behavior of __copy_from_user_inatomic when
it is only partially successful. Instead of returning the number
of bytes not copied, it now returns 1. This translates to the
wrong value being returned by iov_iter_copy_from_user_atomic.
xfstests generic/246 and LTP writev01 both fail on btrfs and nfs
because of this.

Versions of binutils older than 2.16 are already not working, so this
workaround is no longer necessary either. At the same time, some of
the transformations that .code16gcc does can be *extremely*
counterintuitive to a human programmer.

copy_to/from_user_nocheck()
Commit ff47ab4ff3cdd "x86: Add 1/2/4/8 byte optimization to 64bit
__copy_{from,to}_user_inatomic" added a "_nocheck" call in between
the copy_to/from_user() and copy_user_generic(). As both the
normal and nocheck versions of theses calls use the proper __user
annotation, a typecast to remove it should not be added.
This causes sparse to spin out the following warnings:

Since commit 52367a763d8046190754ab43743e42638564a2d1
("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"),
we have failures like this during cxgb4 probe:
cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536]
cxgb4: probe of 0000:01:00.4 failed with error -22
This happens whenever software parameters are used, without a
configuration file. That happens when the hardware was already
initialized (after kexec, or after csiostor is loaded).
It happens that these values are acceptable, rendering fl_pg_order equal
to 0, which is the case of a hard init when the page size is equal or
larger than 65536.
Accepting fl_large_pg equal to fl_small_pg solves the issue, and
shouldn't cause any trouble besides a possible performance reduction
when smaller pages are used. And that can be fixed by a configuration
file.

The Intel Software Developer’s Manual covers few more TLB
configurations exposed as CPUID 2 descriptors:
61H Instruction TLB: 4 KByte pages, fully associative, 48 entries
63H Data TLB: 1 GByte pages, 4-way set associative, 4 entries
76H Instruction TLB: 2M/4M pages, fully associative, 8 entries
B5H Instruction TLB: 4KByte pages, 8-way set associative, 64 entries
B6H Instruction TLB: 4KByte pages, 8-way set associative, 128 entries
C1H Shared 2nd-Level TLB: 4 KByte/2MByte pages, 8-way associative, 1024 entries
C2H DTLB DTLB: 2 MByte/$MByte pages, 4-way associative, 16 entries
Let's detect them as well.

Pull ACPI and PM fixes and new device IDs from Rafael Wysocki:
"These commits, except for one, are regression fixes and the remaining
one fixes a divide error leading to a kernel panic. The majority of
the regressions fixed here were introduced during the 3.12 cycle, one
of them is from this cycle and one is older.
Specifics:
- VGA switcheroo was broken for some users as a result of the
ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some
previously ignored hotplug events started to be handled. The fix
causes them to be ignored again.
- There are two more issues related to cpufreq's suspend/resume
handling changes from the 3.12 cycle addressed by Viresh Kumar's
fixes.
- intel_pstate triggers a divide error in a timer function if the
P-state information it needs is missing during initialization.
This leads to kernel panics on nested KVM clients and is fixed by
failing the initialization cleanly in those cases.
- PCI initalization code changes during the 3.9 cycle uncovered BIOS
issues related to ACPI wakeup notifications (some BIOSes send them
for devices that aren't supposed to support ACPI wakeup). Work
around them by installing an ACPI wakeup notify handler for all PCI
devices with ACPI support.
- The Calxeda cpuilde driver's probe function is tagged as __init,
which is incorrect and causes a section mismatch to occur during
build. Fix from Andre Przywara removes the __init tag from there.
- During the 3.12 cycle ACPIPHP started to print warnings about
missing _ADR for devices that legitimately don't have it. Fix from
Toshi Kani makes it only print the warnings where they make sense"
