[PATCH 4/8] x86-64, ia32: Move compat_ni_syscall into C and its own file

From: H. Peter Anvin
Date: Thu Nov 17 2011 - 17:38:39 EST


From: "H. Peter Anvin" <hpa@xxxxxxxxxxxxxxx>

Move compat_ni_syscall out of ia32entry.S and into its own .c file.
Although this is a trivial function, it is not performance-critical,
and this will simplify further cleanups.
