x86, syscall: Allow syscall offset to be symbolic
Allow the specified syscall offset to be symbolic, e.g. a macro. For offset system calls, this if nothing else makes the generated code easier to read. Suggested-by: H. J. Lu <hjl.tools@gmail.com> Link: http://lkml.kernel.org/r/1321569446-20433-7-git-send-email-hpa@linux.intel.com Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
