Either that or adjust how we do atomic operations. I can do 64-bit
atomic widgetry, but not with the code as written.
Ultra can do it as well, and as far as I understand it ia64 64-bit

It is not even 32bit on sparc32 (24bit only).

page_table_lock is supposed to protect normal page table activity (like
what's done in page fault handler) from swapping out.
However, grabbing this lock in swap-out code is completely missing!

OK, here's an updated Linux 2.4 TODO list. It's actually somewhat up
to date as for test10-pre1, but there a bunch of test10-pre1 bug reports
that defied easy categoricalization (i.e., real bug vs. PEBCAK) so I've
left the offical page as saying that it's hopefully up-to-date as of
pre9.
