Fix a bug in ucas_32 and ucas_64. There is a branch where they don't
initialize %rax.

style, reduces an incoming diff

Split comment, otherwise it is misleading. kcopy operates on kernel
memory, and must *not* be used with userland pages.
--
Move incq outside of the copy section. No functional change, reduces
my smap diff.
--
Remove dumb debug code and outdated comment.
--
Don't forget to clean l_md.md_flags, otherwise there may be MDL_COMPAT32,
in which case the kernel would always use iret (slower).
