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.

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.
