Yeah, it was a stupid typo in
1527bc8b928dd1399c3d3467dd47d9ede210978a. I've fixed it and put the
patch in my tree for Linus.

Unfortunately, there's another compile error--PCI breakage. I'll do this too...

Thanks,
Matt

Ah, now the offending commit is pointed out to me I can see the trivial 
fix.  With that, as you say, compilation now bombs out in the pci-sysfs 
stuff.  Since you claim to have that in hand I'll await your solution.

Cheers
Michael.

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

Your 83926ce2dd37e4337ecf53b1e435d08e70b5871b will work, but you can
also simply drop the filp from pci_mmap_resource().  That's an internal
helper (local to alpha/kernel/pci-sysfs.c) and doesn't require the filp.
Sorry, that was my fault, and should be localized to 2.6.35-rc.
