Jason,
	I know there is disagreement about the proper ultimate resolution of
this problem, but I also think that the code you wrote should be committed as
a first approximation of a fix that we can improve upon later. Right now, a
userland program doing physio on any buffer boundary other than 16-byte aligned
on the affected system causes an instant system crash (no panic, just system
go bye-bye).
