[PATCH] compile fix for voyager with gcc-3.3

From: James Bottomley <James.Bottomley@SteelEye.com>

The cpu_callout_map differs from the prototype in asm-i386/smp.h by a
volatile.  gcc-3.3 now treats this as an error, so voyager support will
only compile with older gcc's.  The fix is to remove the spurious volatile.
