mm: slub: Default slub_max_order to 0

To avoid locking and per-cpu overhead, SLUB optimisically uses
high-order allocations up to order-3 by default and falls back to
lower allocations if they fail. While care is taken that the caller
and kswapd take no unusual steps in response to this, there are
further consequences like shrinkers who have to free more objects to
release any memory. There is anecdotal evidence that significant time
is being spent looping in shrinkers with insufficient progress being
made (https://lkml.org/lkml/2011/4/28/361) and keeping kswapd awake.

SLUB is now the default allocator and some bug reports have been
pinned down to SLUB using high orders during operations like
copying large amounts of data. SLUBs use of high-orders benefits
applications that are sized to memory appropriately but this does not
necessarily apply to large file servers or desktops.  This patch
causes SLUB to use order-0 pages like SLAB does by default.
There is further evidence that this keeps kswapd's usage lower
(https://lkml.org/lkml/2011/5/10/383).

msm: hotplug: Add MSM Hotplug driver

Change-Id: Ia7cf04299b2147edb804a020aeafc56ae501001f
msm: hotplug: Max 1036MHz during screen off
msm: hotplug: Remove spinlock in load stats

It's too expensive and not nessecary.
msm: hotplug: Stop hotplug work a tad later
msm: hotplug: Schedule suspend/resume work

Dennis is right, this is the proper way to suspend and resume.
hammerhead: touch: Remove touch boost

Revert "cpufreq: conservative: Boost all online cpus"

This reverts commit 3d2675da0500e4e9cd94de66f657790ca5e26467.

Revert "hammerhead: touch: Simple method of boosting cpu frequency on touch"

msm: hotplug: Increase down lock duration and janitize
msm: hotplug: Use high-priority workqueue
msm: hotplug: Add input boost handler

Add an input handler to hotplug additional cpus. Down lock will
take care of keeping the cpu boosted.
msm: hotplug: Add minimum interval for input boost
msm: hotplug: Remove deprecated msm_cpufreq_set_freq_limits
cpufreq: add new routine cpufreq_verify_within_cpu_limits()

Most of the users of cpufreq_verify_within_limits() calls it for
limiting with min/max from policy->cpuinfo. We can make that code
simple by introducing another routine which will do this for them
automatically.

This patch adds another routine cpufreq_verify_within_cpu_limits()
and updates others to use it.
