2cdf99ce2b Staging: android: mark subsystem as broken
It's causing lots of build errors, so just mark it as broken.  It is
scheduled to be removed in 2.6.33 anyway.

a5ca2dfc4e staging: Make some structures static
This was done using a semantic patch (http://coccinelle.lip6.fr/) that
checks that the declaration is not inside a function definition, that the
defined variable is not exported using EXPORTED_SYMBOL, etc, and that the
defined variable does not occur in any other file.  If these conditions
hold, static is added before the declaration.

0984e56a65 Staging: android: lowmemorykiller: fix module param errors
Move module_params to near the end of the source file so that
their references are already known/defined.  Fixes build errors:

drivers/staging/android/lowmemorykiller.c: In function '__check_cost':
drivers/staging/android/lowmemorykiller.c:60: error: 'lowmem_shrinker' undeclared (first use in this function)
drivers/staging/android/lowmemorykiller.c: At top level:

drivers/staging/android/lowmemorykiller.c:60: warning: type defaults to 'int' in declaration of 'type name'

34006e11ee Staging: android: lowmemorykiller: cleanup android low memory killer
Clean up the code in lowmem_shrink() for the Android low memory killer so
that it follows the kernel coding style.

It's unnecessary to check for p->oomkilladj >= min_adj if the selected
task's oomkilladj score is stored since get_mm_rss() will always be
greater than zero.

f501d00144 Staging: android: lowmemorykiller: Only iterate over process list when needed.
Use NR_ACTIVE plus NR_INACTIVE as a size estimate for our fake cache
instead the sum of rss. Neither method is accurate.

Also skip the process scan, if the amount of memory available is above
the largest threshold set.

861a0dcc39 Staging: binder: Defer flush and release operations to avoid deadlocks.
If a transaction that contains a file descriptor fails on a later object,
the new file descriptor needs to be closed. If this is a binder file
descriptor we would deadlock in flush. If there were no other references to
the file at this point release would also be called.
