From 3f86886c72fb68088162c7e08cc7f85282f1860c Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 18 Nov 2011 17:01:19 -0800 Subject: 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.
