msm: kgsl: use the same logic in adreno_idle and adreno_isidle

These two functions need to agree on the meaning of "idle",
so that calling adreno_isidle() right after an adreno_idle()
will always return true.

CHROMIUM: mm: Fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate
number of dirtyable pages/pages that can be allocated
to the page cache.  A bug causes an underflow thus making
the page count look like a big unsigned number.  This in turn
confuses the dirty writeback throttling to aggressively write
back pages as they become dirty (usually 1 page at a time).

Fix is to ensure there is no underflow while doing the math.
