Subject: x86, um: Correct syscall table type attributes breaking gcc 4.8
From: Martin Pelikan <pelikan@xxxxxxxxxxxx>
commit 9271b0b4b2044c6db06051fe60bc58cdd4f17c7c upstream.
The latest GCC 4.8 does some more checking on type attributes that
break the build for ARCH=um -> fill them in. Specifically, the
"asmlinkage" attributes is now tested for consistency.
