* 'x86-syscall-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Move <asm/asm-offsets.h> from trace_syscalls.c to asm/syscall.h
x86, um: Fix typo in 32-bit system call modifications
um: Use $(srctree) not $(KBUILD_SRC)
x86, um: Mark system call tables readonly
x86, um: Use the same style generated syscall tables as native
um: Generate headers before generating user-offsets.s
um: Run host archheaders, allow use of host generated headers
kbuild, headers.sh: Don't make archheaders explicitly
x86, syscall: Allow syscall offset to be symbolic
x86, syscall: Re-fix typo in comment
x86: Simplify syscallhdr.sh
x86: Generate system call tables and unistd_*.h from tables
checksyscalls: Use arch/x86/syscalls/syscall_32.tbl as source
x86: Machine-readable syscall tables and scripts to process them
trace: Include <asm/asm-offsets.h> in trace_syscalls.c
x86-64, ia32: Move compat_ni_syscall into C and its own file
x86-64, syscall: Adjust comment spacing and remove typo
kbuild: Add support for an "archheaders" target
kbuild: Add support for installing generated asm headers
