[PATCH 0/6] Subset of watchdog fixes

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

These have been pending since May with Wim occasionally surfacing to promise
something will happen then vanishing again with nothing moved on.

The patch set is a tiny subset of the complete set of patches to clean up the
locking bugs, switch to unlocked_ioctl and the like for watchdog drivers

These specific ones are the ones that
- Remove use of inb_p() on PCI bus which is unsafe with some newer boxes
- Switch from using a sempahore held across the return to user space for
  watchdog locking - and thus help remove more users of down_trylock.
