Okay, thanks for the update, that's equivalent to the get_cpu_var
plus put_cpu_var patch I had generally been running with successfully.

(I was not at all confident that it was a sufficient fix, and have
to say "generally" above because one time I got something that looked
like recursive calls overflowing the stack, and IIRC something "irq"
did appear in each frame of the trace.  But probably no connection,
never seen again, and I don't recall even which -rc or -next it was.)

If you ever see that again, please shoot me the log !

Cheers,
Ben.
