Since 2.5.31-mm1:
- A bunch of things from 2.5.31-mm1 were merged.
- The BKL consolidation patch is dropped because Linus did it too.
- The `might_sleep()' debug patch lost its supporting infrastructure
and I've dropped it for now.
- The configurable PAGE_OFFSET patch ran aground on some kbuild changes and
needs some more work.

Bah. Sorry about that. cpu_possible() appears to be undefined
for uniprocessor builds.
How about this?

Now it compiles and runs fine, thanks!
Although there are several error messages appearing in dmesg related to
ide-scsi, but I guess this is a general 2.5.32 issue:

2.5.32-mm1 fixes some page allocation failures on 3.75 GB
quad xeon. 2.5.32 vanilla had a lot of these:
page allocation failure. order:0, mode:0x50
The page alloc failures began showing up in the first few minutes
of testing (dbench). 2.5.32 stopped responding after about 4
hours of testing.
2.5.32-mm1 has been testing for over 14 hours with no
page allocation failures.
2.5.32 didn't have page alloc failures on uniprocessor 384 MB
machine during 22 hours of testing.

Yes.

This is fine: techically it's:
BUG_ON(cpu != 0);
Since you can never invoke cpu_possible(cpu) or cpu_online(cpu) for
cpu >= NR_CPUS.

Still, it's a good idea to have a UP version, and fix that naked
reference to "cpu" in cpu_online() which just makes me damn nervous.

Err.. no, I was just checking how many people read my patches.
Linus, please apply,
