There is a race condition between a memcg being torn down and a swapin

to the exiting memcg on swapout (with CONFIG_MEMCG_SWAP extension).
The result is unreclaimable pages pointing to dead memcgs, which can

Hi,
here are two memcg fixes for 3.13.
The race condition in #1 is really long standing AFAICS, I just tagged
stable and will backport and evaluate this for any tree that sends me
a notice.
#2 changes what happens during a charge attempt between a task

The situations in which ACCESS_ONCE() is required are not well documented,
so this commit adds some verbiage to memory-barriers.txt.

Hello!
This series applies some long-needed updates to memory-barriers.txt:
1. Add ACCESS_ONCE() calls where needed to ensure their inclusion
in code copy-and-pasted from this file.
2. Add long atomic examples alongside the existing atomics.
3. Prohibit architectures

Some of the Marvell SoCs use GIC as its interrupt controller,and ICU

So add wakeup entry for such kind of usage.

The Documentation/memory-barriers.txt file was written before the need
for ACCESS_ONCE() was fully appreciated. It therefore contains no
ACCESS_ONCE() calls, which can be a problem when people lift examples
from it. This commit therefore adds

Although the atomic_long_t functions are quite useful, they are a bit
obscure. This commit therefore adds the common ones alongside their
atomic_t counterparts in Documentation/memory-barriers.txt.

The EVENT_CONSTRAINT_END macro defines the end marker as
a constraint with a weight of zero. This was all fine
until we blacklisted the corrupting memory events on
Intel IvyBridge. These events are blacklisted by using
a counter bitmask of zero. Thus, they also get a constraint
weight of zero.
