[PATCH] linux-next: 20090929 - android driver build breaks

[Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>]

Hi Greg,

	next-20090929 randconfig build breaks with
CONFIG_ANDROID_LOW_MEMORY_KILLER=y

drivers/staging/android/lowmemorykiller.c: In function 'lowmem_shrink':
drivers/staging/android/lowmemorykiller.c:111: error: 'struct mm_struct' has no member named 'oom_adj'
make[3]: *** [drivers/staging/android/lowmemorykiller.o] Error 1

Commit 0753ba01e126020bf0f8150934903b48935b697d was reverted back,
which moves back oom_adj from mm_struct to task_struct and commit 
28b83c5193e7ab951e402252278f2cc79dc4d298 moved the oomkilladj
from task_struct to signal_struct. 

Following patch reverts the changes introduced by commit 
a6a9f81ccc9f5c86ccc22bbed1960a57d0316e8b to
drivers/staging/android/lowmemorykiller.c
