Fixes for both breaks are in:
   git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha-2.6.git
for-linus

I know alpha hardware isn't easy to get your hands on to compile test
these changes, but guys, please just send linux-alpha@ the patch and
_I'll_ do it. Both these breaks were not even compile tested.

pci break: 2c3c8bea608866d8bd9dcf92657d57fdcac011c5
hweight break: 1527bc8b928dd1399c3d3467dd47d9ede210978a

Greg, I haven't checked, but if either of these commits are in .34 or
older, then my fixes need to go into -stable.

Thanks,
Matt
