x86, uaccess: Merge prototypes for clear_user/__clear_user
The prototypes for clear_user() and __clear_user() are identical in the 32- and 64-bit headers. No functionality change. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Link: http://lkml.kernel.org/r/1348256595-29119-8-git-send-email-hpa@linux.intel.com
