Pull x86 sigcontext header cleanups from Ingo Molnar: "This series reorganizes and cleans up various aspects of the main sigcontext UAPI headers, such as unifying the data structures and updating/adding lots of comments to explain all the ABI details and quirks. The headers can now also be built in user-space standalone" * 'x86-headers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/headers: Clean up too long lines x86/headers: Remove <asm/sigcontext.h> references on the kernel side x86/headers: Remove direct sigcontext32.h uses x86/headers: Convert sigcontext_ia32 uses to sigcontext_32 x86/headers: Unify 'struct sigcontext_ia32' and 'struct sigcontext_32' x86/headers: Make sigcontext pointers bit independent x86/headers: Move the 'struct sigcontext' definitions into the UAPI header x86/headers: Clean up the kernel's struct sigcontext types to be ABI-clean x86/headers: Convert uses of _fpstate_ia32 to _fpstate_32 x86/headers: Unify 'struct _fpstate_ia32' and i386 struct _fpstate x86/headers: Unify register type definitions between 32-bit compat and i386 x86/headers: Use ABI types consistently in sigcontext*.h x86/headers: Separate out legacy user-space structure definitions x86/headers: Clean up and better document uapi/asm/sigcontext.h x86/headers: Clean up uapi/asm/sigcontext32.h x86/headers: Fix (old) header file dependency bug in uapi/asm/sigcontext32.h
