With the following changes, I was able to compile the "sparc" (32 bit)
arch, using defconfig and crosstool.  There were still plenty of warnings,
but nothing else relating to bitops or cpumasks that I noticed.  This is
working with 2.6.7-mm5.

I have no way to boot test this, but these changes seem obvious enough that
I'd recommend including them.
