This annotates NMI functions with notrace. Some tracers may be able
to live with this, but some cannot. The safest is to turn it off,
it's not particularly interesting anyway.

The kernel decompressor wrapper uses memory located beyond the
end of the image. This might lead to hard to debug problems,
but even if it can be proven to be safe, it is at the very
least unclean. I don't see any advantages either, unless you
count it not being zeroed out as an advantage. This patch
moves the boot-heap area to the bss segment.

I've made a small investigation about vm86.h inclusion rules and it
looks like everything is more or less ok.
Files that rely on asm/vm86.h symbols are:
- kprobes.c
- process_32.c
- signal_32.c
- traps_32.c
- vm86_32.c
File process_32.c includes vm86.h explicitly. We can remove that
include and it won't break anything.
