Another one - I can't get this to build for x86_64. (Skipping over all the
already-mentioned build errors that others have already reported...)

First, I had to do some ad-crock hacking of Kconfig files to get kernel/timer.c
to build right, because otherwise it didn't include any of the defines in
include/kernel/clockchips.c so CLOCK_EVT_NOTIFY_RESUME wasn't defined (either
that, or a #ifdef for GENERIC_TIME had its #endif land in the wrong place?)

And even after that, I hit this:

Then we live long enough to hit this:

(How did *that* one manage to compile for anybody??!?)

After all that, I finally got a clean compile....  Maybe later I'll get brave
and actually try to boot it. :)
