Subject: [PATCH 09/15] x86/headers: Clean up the kernel's struct sigcontext types to be ABI-clean
Use the __u16/32/64 types we standardized on in ABI definitions and which
other sigcontext related types are already using.
This will help unify struct sigcontext types between native 32-bit, compat
and 64-bit kernels.
