Hi Mike,

I agree with the code, but I do have a remark...

The ENTRY() macro already includes the ALIGN, so you could get
rid of the preceding ALIGN. But it's just a neatness thing, because
two consecutive ALIGNS don't change the resulting binary.

At any rate:

Acked-by: Alexander van Heukelum <heukelum@...tmail.fm>

(maybe the x86-committer feels comfortable enough to remove the ALIGN ;)
)
