Add device tree binding for NAND on the BCM6368.
The BCM6368 has a NAND interrupt register with combined status and enable
registers. It also requires a clock, so add an optional clock to the
common brcmnand binding.

The BCM6368 has a NAND interrupt register with combined status and enable

As the BCM6328, BCM6362 and BCM6368 all use v2.1 controllers, the first
variant that will work with this driver is the BCM63268 using a v4.0
controller.

Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in
fs/adfs/adfs.h
since it appears that "adfs: constify adfs_dir_ops structures" has been applied
by Al Viro. There was no conflict to resolve but git still flagged it as a

for some reason.

There haven't been too many workqueue stall bugs; however, good part
of them have been pretty painful to track down because there's no
lockup detection mechanism for workqueue and it isn't easy to tell
what's going on with workqueues; furthermore, some requirements are
tricky to get right -
Workqueue stalls can happen from a variety of usage bugs such as
missing WQ_MEM_RECLAIM flag or concurrency managed work item
indefinitely staying RUNNING. These stalls can be extremely difficult
to hunt down because the usual warning mechanisms can't detect
workqueue stalls and the internal state

We are comparing policy->governor against cpufreq_gov_ondemand to make
sure that we update sampling rate only for the concerned CPUs. But that
isn't enough.
In case of governor_per_policy, there can be multiple instances of
ondemand governor and we will always end up updating all of them with
curr
We are guaranteed to have works scheduled for policy->cpus, as the
policy isn't stopped yet. And so there is no need to check that again.
Drop it.

cpufreq governors evaluate load at sampling rate and based on that they
update frequency for a group of CPUs belonging to the same cpufreq
policy.
This is required to be done in a single thread for all policy->cpus, but
because we don't want to wakeup idle CPUs to do just that, we use
deferrable w
Currently update_sampling_rate() runs over each online CPU and
cancels/queues timers on all policy->cpus every time. This should be
done just once for any cpu belonging to a policy.
Create a cpumask and keep on clearing it as and when we process
policies, so that we don't have to traverse through
This patch uses is_via_compact_memory() to distinguish compaction
from sysfs or sysctl. And, this patch also reduces indentation
on compaction_defer_reset() by filtering these cases first
before checking watermark.
There is no functional change.

Until now, COMPACT_CLUSTER_MAX is defined as SWAP_CLUSTER_MAX.
Commit ("mm: increase SWAP_CLUSTER_MAX to batch TLB flushes")
changes SWAP_CLUSTER_MAX from 32 to 256 to improve tlb flush performance
so COMPACT_CLUSTER_MAX is also changed to 256. But, it has
no justification on compaction-side and I

timer_mutex is required to be initialized only while memory for 'shared'
is allocated and in a similar way it is required to be destroyed only
when memory for 'shared' is freed.
There is no need to do the same every time we start/stop the governor.
