mm: Don't use CMA pages for page cache

All layers of the page cache may take extra references to
pages to avoid migration. This is fine for general movable
pages but renders CMA pages useless as they cannot be
allocated for contiguous mode. Always omitting movable
pages completely has poor utilization of memory so attempt
with the given GFP flags first and if a CMA page is allocated,
free it and get a new non-movable page. This does have a minor
performance impact, but ultimately it's a tradeoff between
never using movable pages and taking the extra hit of a
free/realloc.

cpufreq: Add cpu-boost driver

When certain bursty and important events take place, it might take a while
for the current cpufreq governor to notice the new load and react to it.
That would result in poor user experience. To alleviate this, the cpu-boost
driver boosts the frequency of a CPU for a short duration to maintain good
user experience while the governor catches up.

Specifically, this commit deals with ensuring that when "important" tasks
migrate from a fast CPU to a slow CPU, the frequency of the slow CPU is
boosted to be at least as high as the fast CPU for a short duration.

Since this driver enforces the boost by hooking into standard cpufreq
ADJUST notifiers, it has several advantages:
- More portable across kernel versions where the cpufreq internals might
  have been rewritten.
- Governor agnostic and hence works with multiple governors like
  conservative, ondemand, interactive, etc.
- Does not affect the sampling period/logic of existing governors.
- Can have the boost period adjusted independent of governor sampling
  period.

cpufreq: Add a sync limit to cpu-boost

Perform frequency synchronization only when source CPU's frequency
is less than sync_threshold, else sync to the sync_threshold.
