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).

Ok, what has changed from your previous version that I rejected that is
going to actually allow this to build?
I had to add <linux/compat.h> for a successful build on x86_64. The
attached hunk is the only change added.

Hint, you gotta tell me what version of the patch this is, and what
changed, otherwise I'll just assume this is a resend of the previous
patch and go ahead and delete it from my queue.
Sorry - same patch as before, the one that had John and Arve's ack, plus
the above hunk.
In fact, I might as well do that, now deleted :)
