Subject: [PATCH 0/3] remove irq_sem cruft from e1000 and derivatives

Hey folks --

     While digging through the atl1 source, I was troubled by the code using
irq_sem.  I did some digging and found the same code in e1000 and ixgb.  I'm
not entirely sure what it was originally intended to do, but it doesn't seem
to be doing anything useful now, except possibly locking interrupts off if
NAPI is flipped on and off enough times to cause an integer overflow.

     The following patches completely remove irq_sem from each of the drivers.
 This has been tested successfully on atl1 and e1000.  If someone would like
to send me ixgb hardware I'd be glad to test that, otherwise you'll have to
test it yourself. :)

     -- Chris
