The following patch makes the microcode update code path
actually invoke the perf_check_microcode() function and
thus potentially renabling SNB PEBS.
By default, CONFIG_MICROCODE_OLD_INTERFACE is
forced to Y in arch/x86/Kconfig. There is no
way to disable this. That means that the code
path used in arch/x86/kernel/microcode_core.c
did not include the call to perf_check_microcode().
Thus, even though the microcode was updated to a
version that fixes the SNB PEBS problem, perf_event
would still return EOPNOTSUPP when enabling precise
sampling.
This patch simply adds a call to perf_check_microcode()
in the call path used when OLD_INTERFACE=y.

Pull LogFS bugfixes from Prasad Joshi:
- "logfs: query block device for number of pages to send with bio"
This BUG was found when LogFS was used on KVM. The patch fixes
the problem by asking for underlaying block device the number
of pages to send with each BIO.
- "logfs: maintain the ordering of meta-inode destruction"
LogFS maintains file system meta-data in special inodes. These
inodes are releated to each other, therefore they must be
destroyed in a proper order.
- "logfs: initialize the number of iovecs in bio"
LogFS used to panic when it was created on an encrypted LVM
volume. The patch fixes the problem by properly initializing
the BIO.
Plus a couple more:
- logfs: create a pagecache page if it is not present
- logfs: destroy the reserved inodes while unmounting

Commit 412312 (ASoC: dapm: Make sure all dapm contexts are updated) means
that any DAPM context being updated will have the bias level automatically
set, including the card. We can't safely do this as the card callbacks are
called for each device context and so the management of the card bias is
more complex. Several multi-component cards rely on this behaviour.
Skip updates during the asynchronous run entirely. We should really do them
in the synchronous section but it's not 100% clear which values to pick as
the different DAPM contexts may have different bias levels.

With !HIGHMEM, sanity_check_meminfo checks for banks that completely or
partially overlap the vmalloc region. The test for partial overlap checks
__va(bank->start + bank->size) > vmalloc_min. This is not appropriate if
there is a non-linear translation between virtual and physical addresses,
as bank->start + bank->size is actually in the bank following the one being
interrogated.
In most cases, even when using SPARSEMEM, this is not problematic as the
subsequent bank will start at a higher va than the one in question. However
if the physical to virtual address conversion is not monotonic increasing,
the incorrect test could result in a bank not being truncated when it
should be.
This patch ensures we perform the va-pa conversion on memory from the
bank we are interested in, not the following one.

When enabling the MMU for ARMv7 CPUs, the decompressor does not touch
the ttbcr register, assuming that it will be zeroed (N == 0, EAE == 0).
Given that only EAE is defined as 0 for non-secure copies of the
register (and a bootloader such as kexec may leave it set to 1 anyway),
we should ensure that we reset the register ourselves before turning on
the MMU.
This patch zeroes TTBCR.EAE and TTBCR.N prior to enabling the MMU for
ARMv7 cores in the decompressor, configuring us exclusively for 32-bit
translation tables via TTBR0.

From ARM debug architecture v7.1 onwards, a watchpoint exception causes
the DFAR to be updated with the faulting data address. However, DFSR.WnR
takes an UNKNOWN value and therefore cannot be used in general to
determine the access type that triggered the watchpoint.
This patch forbids watchpoints without an overflow handler from
specifying a specific access type (load/store). Those with overflow
handlers must be able to handle false positives potentially triggered by
a watchpoint of a different access type on the same address. For
SIGTRAP-based handlers (i.e. ptrace), this should have no impact.

The GPIO buttons are named SW3, SW4, SW5 and SW6 on the board
silkscreen. Update the buttons descriptions accordingly.

====================
here are two fixes for the v3.6 release cycle. Alexey Khoroshilov submitted a
fix for a memory leak in the softing driver (in softing_load_fw()) in case a
krealloc() fails. Sven Schmitt fixed the misuse of the IRQF_SHARED flag in the
irq resouce of the sja1000 platform driver, now the correct flag is used. There
are no mainline users of this feature which need to be converted.

John W. Linville says:
====================
This batch of fixes is intended for 3.6...
Johannes Berg gives us a pair of iwlwifi fixes. One corrects some
improperly defined ifdefs that lead to crashes and BUG_ONs. The other
prevents attempts to read SRAM for devices that aren't actually started.
Julia Lawall provides an ipw2100 fix to properly set the return code
from a function call before testing it! :-)
Thomas Huehn corrects the improper use of a constant related to a power
setting in ath5k.
Thomas Pedersen offers a mac80211 fix to properly handle destination
addresses of unicast frames passing though a mesh gate.
Vladimir Zapolskiy provides a brcmsmac fix to properly mark the
interface state when the device goes down.

The cwnd reduction in fast recovery is based on the number of packets
newly delivered per ACK. For non-sack connections every DUPACK
signifies a packet has been delivered, but the sender mistakenly
skips counting them for cwnd reduction.
The fix is to compute newly_acked_sacked after DUPACKs are accounted
in sacked_out for non-sack connections.

Non-root user-space processes can send Netlink messages to other
processes that are well-known for being subscribed to Netlink
asynchronous notifications. This allows ilegitimate non-root
process to send forged messages to Netlink subscribers.
The userspace process usually verifies the legitimate origin in
two ways:
a) Socket credentials. If UID != 0, then the message comes from
some ilegitimate process and the message needs to be dropped.
b) Netlink portID. In general, portID == 0 means that the origin
of the messages comes from the kernel. Thus, discarding any
message not coming from the kernel.
However, ctnetlink sets the portID in event messages that has
been triggered by some user-space process, eg. conntrack utility.
So other processes subscribed to ctnetlink events, eg. conntrackd,
know that the event was triggered by some user-space action.
Neither of the two ways to discard ilegitimate messages coming
from non-root processes can help for ctnetlink.
This patch adds capability validation in case that dst_pid is set
in netlink_sendmsg(). This approach is aggressive since existing
applications using any Netlink bus to deliver messages between
two user-space processes will break. Note that the exception is
NETLINK_USERSOCK, since it is reserved for netlink-to-netlink
userspace communication.
Still, if anyone wants that his Netlink bus allows netlink-to-netlink
userspace, then they can set NL_NONROOT_SEND. However, by default,
I don't think it makes sense to allow to use NETLINK_ROUTE to
communicate two processes that are sending no matter what information
that is not related to link/neighbouring/routing. They should be using
NETLINK_USERSOCK instead for that.

Multicast traffic allocates dst with DST_NOCACHE, but dst is
not inserted into rt_uncached_list.
This slowdown multicast workloads on SMP because rt_uncached_lock is
contended.
Change the test before taking the lock to actually check the dst
was inserted into rt_uncached_list.

This board is incorrectly detected as having an LVDS connector,
resulting in the VGA output (the only available output on the board)
showing the console only in the top-left 1024x768 pixels, and an extra
LVDS connector appearing in X.
It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10
chipset.
I've had this board for about a year, but this is the first time I
noticed the issue because I've been running it headless for most of its
life.
