x86: use macros from asm.h.2008-07-09T07:14:12+00:00Glauber Costagcosta@redhat.com2008-06-24T20:36:31+00:00urn:sha1:2528de431ddb200653d1dc6ca90074bad9520f09
In putuser_32.S and putuser_64.S, replace things like .quad, .long,
and explicit references to [r|e]ax for the apropriate macros
in asm/asm.h.

x86: replace function headers by macros.2008-07-09T07:14:10+00:00Glauber Costagcosta@redhat.com2008-06-24T19:56:30+00:00urn:sha1:766ed4282114eab616741107745b0dd11075e496
In putuser_64.S, do it the i386 way, and replace the code
in beginning and end of functions with macros, since it's
always the same thing. Save lines.

x86: change testing logic in putuser_64.S.2008-07-09T07:14:09+00:00Glauber Costagcosta@redhat.com2008-06-24T19:51:59+00:00urn:sha1:663aa96df32af9c4141ef3179282f95c7537643a
Instead of operating over a register we need to put back
into normal state afterwards (the memory position), just
sub from rbx, which is trashed anyway. We can save a few instructions.
Also, this is the i386 way.
