Linus is accepting, let's save people from the hastle of having to
patch v3.8 back into working or use a stable kernel.
Looking at the diffstat, this really is high value for its size; this
is miniscule compared to how the -rc6 to tip diffstat currently looks.
So, four patches in this set:
- Punit Agrawal reports that the kernel no longer boots on MPCore due
to a new assumption made in the GIC code which isn't true of
earlier GIC designs. This is the biggest change in this set.
- Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
the DT-ification of the GIC support without fixing up non-DT
Realview - which now sees a greater number of interrupts than it
did before.
- A fix for the DMA coherent code from Marek which uses the wrong
check for atomic allocations; this can result in spinlock lockups
or other nasty effects.
- A fix from Will, which will affect all Android based platforms if
not applied (which use the 2G:2G VM split) - this causes
particularly 'make' to misbehave unless this bug is fixed."

ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned
We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).
Further investigation reveals that this regression was triggered by
394ef6403abc ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.
This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.
GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested. GFP_ATOMIC is not a flag but
a value. The GFP bitmask flags are all prefixed with __GFP_.
The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation. We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register. This means we can't rely on that telling us
which CPU interface we're connected to. We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.
So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

xen/netback: shutdown the ring if it contains garbage.
A buggy or malicious frontend should not be able to confuse netback.
If we spot anything which is not as it should be then shutdown the
device and don't try to continue with the ring in a potentially
hostile state. Well behaved and non-hostile frontends will not be
penalised.
As well as making the existing checks for such errors fatal also add a
new check that ensures that there isn't an insane number of requests
on the ring (i.e. more than would fit in the ring). If the ring
contains garbage then previously is was possible to loop over this
insane number, getting an error each time and therefore not generating
any more pending requests and therefore not exiting the loop in
xen_netbk_tx_build_gops for an externded period.
Also turn various netdev_dbg calls which no precipitate a fatal error
into netdev_err, they are rate limited because the device is shutdown
afterwards.
This fixes at least one known DoS/softlockup of the backend domain.

drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd try
This fixes up
commit
e8e89622ed361c46bf90ba4828e685a8b603f7e5
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Tue Dec 18 22:25:11 2012 +0100
drm/ttm: fix fence locking in ttm_buffer_object_transfer
which leaves behind a might_sleep in atomic context, since the
fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix
is to revert the above commit and only take the lock where we need it,
around the call to ->sync_obj_ref.
v2: Fixup things noticed by Maarten Lankhorst:
- Brown paper bag locking bug.
- No need for kzalloc if we clear the entire thing on the next line.
- check for bo->sync_obj (totally unlikely race, but still someone
else could have snuck in) and clear fbo->sync_obj if it's cleared
already.

Btrfs: fix race between snapshot deletion and getting inode
While running snapshot testscript created by Mitch and David,
the race between autodefrag and snapshot deletion can lead to
corruption of dead_root list so that we can get crash on
btrfs_clean_old_snapshots().
And besides autodefrag, scrub also does the same thing, ie. read
root first and get inode.
Here is the story(take autodefrag as an example):
(1) when we delete a snapshot or subvolume, it will set its root's
refs to zero and do a iput() on its own inode, and if this inode happens
to be the only active in-meory one in root's inode rbtree, it will add
itself to the global dead_roots list for later cleanup.
(2) after (1), the autodefrag thread may read another inode for defrag
and the inode is just in the deleted snapshot/subvolume, but all of these
are without checking if the root is still valid(refs > 0). So the end up
result is adding the deleted snapshot/subvolume's root to the global
dead_roots list AGAIN.
Fortunately, we already have a srcu lock to avoid the race, ie. subvol_srcu.
So all we need to do is to take the lock to protect 'read root and get inode',
since we synchronize to wait for the rcu grace period before adding something
to the global dead_roots list.

IPoIB: Fix crash due to skb double destruct
After commit
b13912bbb4a2 ("IPoIB: Call skb_dst_drop() once skb is
enqueued for sending"), using connected mode and running multithreaded
iperf for long time, ie
iperf -c <IP> -P 16 -t 3600
results in a crash.
After the above-mentioned patch, the driver is calling skb_orphan() and
skb_dst_drop() after calling post_send() in ipoib_cm.c::ipoib_cm_send()
(also in ipoib_ib.c::ipoib_send())
The problem with this is, as is written in a comment in both routines,
"it's entirely possible that the completion handler will run before we
execute anything after the post_send()." This leads to running the
skb cleanup routines simultaneously in two different contexts.
The solution is to always perform the skb_orphan() and skb_dst_drop()
before queueing the send work request. If an error occurs, then it
will be no different than the regular case where dev_free_skb_any() in
the completion path, which is assumed to be after these two routines.

drivers/rtc/rtc-pl031.c: fix the missing operation on enable
The RTC control register should be enabled in the process of
initializing.
Without this patch, I failed to enable RTC in Hisilicon Hi3620 SoC. The
register mapping section in RTC is always read as zero. So I doubt that
ST guys may already enable this register in bootloader. So they won't
meet this issue.

samples/seccomp: be less stupid about cross compiling
The seccomp filters are currently built for the build host, not for the
machine that they are going to run on, but they are also built for with
the -m32 flag if the kernel is built for a 32 bit machine, both of which
seems rather odd.
It broke allyesconfig on my machine, which is x86-64, but building for
32 bit ARM, with this error message:
In file included from /usr/include/stdio.h:28:0,
from samples/seccomp/bpf-fancy.c:15:
/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory
because there are no 32 bit libc headers installed on this machine. We
should really be building all the samples for the target machine rather
than the build host, but since the infrastructure for that appears to be
missing right now, let's be a little bit smarter and not pass the '-m32'
flag to the HOSTCC when cross- compiling.

checkpatch: fix $Float creation of match variables
Commit
74349bccedb3 ("checkpatch: add support for floating point
constants") added an unnecessary match variable that caused tests that
used a $Constant or $LvalOrFunc to have one too many matches.
This causes problems with usleep_range, min/max and other extended
tests.
Avoid using match variables in $Float.
Avoid using match variables in $Assignment too.

memcg: fix typo in kmemcg cache walk macro
The macro for_each_memcg_cache_index contains a silly yet potentially
deadly mistake. Although the macro parameter is _idx, the loop tests
are done over i, not _idx.
This hasn't generated any problems so far, because all users use i as a
loop index. However, while playing with an extension of the code I
ended using another loop index and the compiler was quick to complain.
Unfortunately, this is not the kind of thing that testing reveals =(
