lock must not be held across the driver/ldisc downcalls.

Some drivers need to set device state (baudrate etc) and may
need to sleep.

Jeff Mahoney notes:

 "generic_shutdown_super() will happily call the ->put_super fs method,
  destroying data structures still in use by the iput (->delete_inode)
  in progress. 

  The unlink path will call the ->unlink fs method, release the path
  (thus dropping the reference to the vfsmount, and then call iput.
  Since the vfsmount reference is dropped back to 1, a umount will
  succeed, causing the superblock to be cleaned up."

Arrgh...  Here's the trivial fix: do the final "iput()" a bit earlier in
the unlink path. 

Note: all places that go to exit1: or exit: will have NULL inode, so we
are not leaking anything here and it is OK do that iput() early; indeed,
the goal of that kludge was to postpone the final iput() past the
unlocking the parent for the sake of contention if a wunch of bankers is
doing parallel unlink() on files in the same directory and normally it
would happen on dput() after vfs_unlink())

A bug in function piix_config_drive_xfer_rate() allows a call of
hwif->ide_dma_on(drive) without prior call of piix_config_drive_for_dma().
This results in harddisk configured for UDMA (default?) whereas the highest
DMA mode supported by PIIX3 is MWORD2.

This bug is supposed to be present in any 2.6.x kernel release and any
2.4.x kernel release since 2.4.21.

Move the simple can_do_mlock() check before the full rlimits based
restriction checks for mlock() and mlockall().  As it is, the check
adds nothing.  This has a side-effect of eliminating an unnecessary call

We recently changed the VSID allocation on PPC64 to use a new scheme
based on a multiplicative hash.  It turns out our choice of multiplier
(the largest 28-bit prime) wasn't so great: with large contiguous
mappings, we can get very poor hash scattering.  In particular earlier
machines (without 16M pages) which had a reasonable about of RAM (>2G
or so) wouldn't boot, because the linear mapping overflowed some hash
buckets.

This patch changes the multiplier to something which seems to work
better (it is, rather arbitrarily, the median of the primes between
2^27 and 2^28).  Some more theory should almost certainly go into the
choice of this constant, to avoid more pathological cases.  But for
now, this choice fixes a serious bug, and seems to do at least as well
at scattering as the old choice on a handful of simple testcases.
