vfs: fix pipe counter breakage

commit a930d8790552658140d7d0d2e316af4f0d76a512 upstream.

If you open a pipe for neither read nor write, the pipe code will not
add any usage counters to the pipe, causing the 'struct pipe_inode_info"
to be potentially released early.

That doesn't normally matter, since you cannot actually use the pipe,
but the pipe release code - particularly fasync handling - still expects
the actual pipe infrastructure to all be there.  And rather than adding
NULL pointer checks, let's just disallow this case, the same way we
already do for the named pipe ("fifo") case.

This is ancient going back to pre-2.4 days, and until trinity, nobody
naver noticed.

msm: memory: remove obsolete stable_size function

The notion of `stable' memory is going away (i.e. all memory is now
treated as `stable'). Remove the stable_size function. Remove the
notion of stability from the total_stable_size function and rename it
to total_size.

msm: memory: use memblock instead of meminfo

msm currently uses meminfo (not memblock) in memory.c for several
purposes (mainly the placement of the memory pool(s)).  When the code
was written originally, memblock didn't exist yet.

Now that memblock exists, this is not strictly correct, but works as
long as nobody calls memblock_remove() besides this code (if that
occurs then the meminfo data no longer reflect reality and will likely
cause overlap problems).

To avoid problems meminfo usage should be replaced with memblock.

Also, since memblock regions of the same type can't be contiguous, the
total_size function, which calculated the aggregate size of contiguous
meminfo banks, can be removed.

msm thermal: enhancements

1) Smart polling based on temp (poll slower when cooler, faster when
warmer).

2) Added low frequency index so we don't throttle too low and kill
performance. When warming normally (throttle temp is reached) it will
step down by the freq_step until back under control. The lowest
frequency step possible is the specified by the low freq index.

3) Added throttle max (hardcoded at 80C). If it reaches the
throttle max, it will immediately throttle down to the min_freq_index
instead of stepping down 2 frequency steps at a time like when it hits
the throttle temp.

4) Added tuneables
