This patch breaks the build on my machine:
drivers/staging/android/ashmem.c: In function ‘compat_ashmem_ioctl’:
drivers/staging/android/ashmem.c:711:7: error: ‘compat_size_t’ undeclared (first use in this function)
drivers/staging/android/ashmem.c:711:7: note: each undeclared identifier is reported only once for each function it appears in

so of course, I can't take it :(
