beginning of macroectomy in pf.c: RR and WR macros replaced with saner
inlines a-la pcd.c

mtdblock_ro switched to use of gendisk, both mtdblock.c and mtdblock_ro.c
slightly cleaned up.

jsflash switched to use of gendisk

assorted minor cleanups

devfs-related stuff moved from cdrom.c and cdrom drivers to register_disk();
new flag (GENHD_FL_CD) marks gendisks that need such treatment.

sbpcd switched to use of gendisk

mcdx switched to use of gendisk

mcd switched to use of gendisk, failure path in module_init cleaned up

cm206 switched to use of gendisk, failure path in module_init cleaned up

cdu31a switched to use of gendisk

pcd switched to use of gendisk

the attached patch (against BK-curr) fixes a bug in the new PID allocator,
which bug can cause incorrect hashing of the PID structure which causes
infinite loops in find_pid(). [and potentially other problems.]

Patch from Rohit Seth: allow hugetlb pages to be allocated from the
highmem zone.

From Marcus Alanen <maalanen@ra.abo.fi>

Don't retake the zone lock after spilling a batch of pages into the
buddy.

Instead, just clear local variable `zone' to indicate that no lock is
held.

This is actually a common case - whenever release_pages() is called
with exactly 16 pages (truncate, page reclaim..) Marcus' patch will
save a lock and an unlock.

Also, remove some lock-avoidance heuristics in
pagevec_deactivate_inactive(): the caller has already made these
checks, and the chance of the check here actually doing anything useful
is negligible.

- Spell Jeremy's name correctly.

- Fix compile warning in raw.c

- Do a waitqueue_active() test before waking klogd in printk.

  Not only is is negligibly faster, but the wake_up() in there causes
  deadlocks when you try to print debug info out from inside scheduler
  code.

  This patch gives a delightfully obscure way of avoiding the
  deadlock: kill off klogd.

- Fix a couple of compile warnings in the mtrr code.
