3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ricky Liang <jcliang@chromium.org>
commit affa80bd97f7ca282d1faa91667b3ee9e4c590e6 upstream.
When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS
ioctl needs to be treated with special care, as it has the pointer
size encoded in the command.
