squashed: glibc versions:

the kernel's memcpy and memmove is very inefficient. But the glibc version is
quite fast, in some cases it is 10 times faster than the kernel version. So I
introduce some memory copy macros and functions of the glibc to improve the
kernel version's performance.

The strategy of the memory functions is:
1. Copy bytes until the destination pointer is aligned.
2. Copy words in unrolled loops.  If the source and destination are not
   aligned in the same way, use word memory operations, but shift and merge
   two read words before writing.
3. Copy the few remaining bytes.

the performance of memcpy and memmove of the general version is very
inefficient, this patch improved them.

msm_thermal: New thermal driver

The code in the HTC dump is completely broken.  Rewritten to work
and to support more aggressive lower-end throttling and configurability.

There are three throttling tiers defined at 60C, 70C, 80C where we
throttling to 1.3GHz, 900Mhz, 380MHz.  The goal is to spead more time
at 1.3 and stay at a mid temp than shoot straight up to the 900Mhz
throttling.  Added the top level to add a safety net for going too hot.

All the parameters are exposed in /sys/module/msm_thermal/parameters.

SELinux: include definition of new capabilities

The kernel has added CAP_WAKE_ALARM and CAP_EPOLLWAKEUP.  We need to
define these in SELinux so they can be mediated by policy.

writeback: fix occasional slow sync(1)

In case when system contains no dirty pages, wakeup_flusher_threads() will
submit WB_SYNC_NONE writeback for 0 pages so wb_writeback() exits
immediately without doing anything, even though there are dirty inodes in
the system.  Thus sync(1) will write all the dirty inodes from a
WB_SYNC_ALL writeback pass which is slow.

Fix the problem by using get_nr_dirty_pages() in wakeup_flusher_threads()
instead of calculating number of dirty pages manually.  That function also
takes number of dirty inodes into account.

cpufreq: Save user policy min/max instead of policy min/max during hotplug

When a CPU is hotplugged off, various fields of the policy are saved so
that they can be restored when the CPU is hotplugged back in.

The existing code saves the policy min/max field during hotplug remove and
restores it into user policy min/max during hotplug add. This results in
the loss of the user policy min/max values across a hotplug remove/add.

Fix it by saving the user policy min/max instead of policy min/max during
hotplug remove. During a hotplug add, after user policy min/max is
restored, the policy min/max is already recomputed. So, there's no risk of
going beyound any limits imposed by the CPUFREQ_ADJUST/INCOMPATIBLE
notifiers.
