After downing/upping a cpu, an attempt to set
/proc/sys/vm/percpu_pagelist_fraction results in an oops in
percpu_pagelist_fraction_sysctl_handler().

If a processor is downed then we need to set the pageset pointer back to
the boot pageset.

Updates of the high water marks should not access pagesets of unpopulated
zones (those pointer go to the boot pagesets which would be no longer
functional if their size would be increased beyond zero).

After the recent changes that went into mm/vmscan.c to overhaul stuff, we
ended up with these warnings on no-mmu systems:

  mm/vmscan.c: In function `shrink_page_list':
  mm/vmscan.c:580: warning: unused variable `vm_flags'
  mm/vmscan.c: In function `shrink_active_list':
  mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function
  mm/vmscan.c:1242: note: `vm_flags' was declared here

This is because the no-mmu function defines page_referenced() to work on
the first argument only (the page).  It does not clear the vm_flags given
to it because for no-mmu systems, they never actually get utilized.  Since
that is no longer strictly true, we need to set vm_flags to 0 like
everyone else so gcc can do proper dead code elimination without annoying
us with unused warnings.

If a kthread happens to use get_user_pages() on an mm (as KSM does),
there's a chance that it will end up trying to read in a swap page, then
oops in grab_swap_token() because the kthread has no mm: GUP passes down
the right mm, so grab_swap_token() ought to be using it.

We have not identified a stronger case than KSM's daemon (not yet in
mainline), but the issue must have come up before, since RHEL has included
a fix for this for years (though a different fix, they just back out of
grab_swap_token if current->mm is unset: which is what we first proposed,
but using the right mm here seems more correct).

1)In omap_wdt_probe() the watchdog is reset and disabled. This

2)In omap_wdt_open() the timer register needs to be reloaded
to trigger a new timer value (the default of 60s)

one in a million condition where state->dev_ver implies an older Cut
(Cut < 2.0, eventhough the driver doesn't attach to any Cut older than
2.0) or even negative (due to a bad I2C bus master driver) for the card
