kbuild: "PREEMPT" in UTS_VERSION
From: Matt Mackall <mpm@selenic.com> Add PREEMPT to UTS_VERSION where enabled as is done for SMP to make preempt kernels easily identifiable. Added SMP PREEMPT as comment in compile.h to force it to be updated when they change (sam). Signed-off-by: Matt Mackall <mpm@selenic.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
