This has been in the -mm tree for a while and has helped a lot in finding
lots of improper users of the driver core.  It also moves the driver core
code up quite a few levels on the "Rusty's guide to kernel APIs".

Again, from Randy Dunlap

Based on patch from Randy Dunlap.

Need cacheflush.h for change_page_attr()

- sort some of the ATI entries. (note, there are dupes in there
  that could be fixed up at some point).
- Rename PCI_DEVICE_ID_RADEON_IGP to ATI_RS100.
  RadeonIGP is the family, not the specific chip.

If ->group_leader of current thread already was exiting,
group_leader's ->mm is NULL in fill_psinfo(). Then I got Oops.

This uses current->mm instead of ->group_leader->mm to dump args.

- Ensure that arq->state is always set (ie.  even if io context
  allocation failed).

- Call as_antic_stop() unconditionally - which checks for the same
  condition.  There are other callers which make the same check and should
  be changed too...

On failure register_blkdev doesn't necessarly return -ENODEV .. it can return -ENOMEM too.
This patch add a little better audit of register_blkdev.

   Uninitialize static variables initialized to 0
   so they are pushed to the .bss instead of .data.

Patch from Julie DeWandel.

This patch has solved the crashes observed during TPC-C runs on the
16-way box.  (I'm confident it will fix the other reported cases as
well.)

The race is the setting of timer->base to NULL, by del_timer() or
__run_timers().  If new_base == old_base in __mod_timer() then we do not
re-check timer->base after getting the lock.  (the only case where we do
not have to re-check the base is in the !old_base case, but the else
branch also includes the old_base==new_base case.)

The __run_timers() case made the lock_timer() patch not work fully - we
cannot use lock_timer() in __run_timers() due to lock ordering.
