we merge everything that is inside CONFIG_SMP
to smp.h. They differ a little bit, so we use
CONFIG_X86_32_SMP and CONFIG_X86_64_SMP as markers.

This implementation in x86_64 is clean and consistent, but we
sacrifice it for the sake of being equal to i386 (since the other
way around would be harder).

Although those constants are always defined in x86_64,
and will have the effect of just including the headers
in the very way we did before, I'm doing this in a separate
patch to be conservative and avoid surprises.

The code is now the same between i386 and x86_64. We already
know what happens when it reaches this point: They go away
from the arch-specific headers, and suddenly appears in the common
header.

We provide a bogus macro for x86_64 in case CONFIG_X86_LOCAL_APIC
is not set. It will always be set for x86_64, so the effect
is just to make the code equal to i386.

APIC_DEFINITION is not defined in x86_64, so in practice, we keep
our old code here. But as a nice side effect, the code is now
equal to smp_32.h.

Report when microcode was successfully updated. It used to be there but
now with DEBUG unset it becomes very silent. Also some cosmetic fixes.

The new cacheflush.h API's didn't have any comments describing
how they're to be used yet and the conventions around these functions.
This patch adds comments to this effect; in order for that to be
a logical series, some prototypes had to move around.

When compilers became generally better at optimizing code than humans, the
register keyword became mostly useless. For the floppy driver it certainly
is since it's so slow compared to the rest of the system that optimizing
access to a single variable or two isn't going to make any real difference
So let's just leave it to the compiler - it'll do a better job anyway.

This patch does away with a few register keywords in the x86 floppy driver.
