Android's shared memory subsystem, Ashmem, does not support calls from a

coming from a 32bit userspace in a 64bit kernel.
The patch has been successfully tested on ARMv8 AEM(64bit
platform model) and Versatile Express A9(32bit platform).

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
When building for x86_64 we need <linux/compat.h>. Sorry I forgot it,
should build fine now.
so of course, I can't take it :(
Thanks,
Serban
