  libata: fix kernel-doc parameter warning
  sata_mv: remove iounmap in mv_platform_remove and use devm_iomap

Noted by various people (Sam, Jeff, Roland..)

Commit 58b7983d intended to remove the
xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the
tree as a empty file, and would cause git to correctly complain about a
tracked file being removed after a "make distclean" (which removes empty
files as garbage).

And the asm-x86/desc_64.h file was supposed to be removed by commit
c81c6ca4, but instead stayed around
containing just a single newline.

Get rid of them both properly.

This patch implements libata.force module parameter which can
selectively override ATA port, link and device configurations
including cable type, SATA PHY SPD limit, transfer mode and NCQ.

For example, you can say "use 1.5Gbps for all fan-out ports attached
to the second port but allow 3.0Gbps for the PMP device itself, oh,
the device attached to the third fan-out port chokes on NCQ and
shouldn't go over UDMA4" by the following.

At present, the __spufs_trap_data_map and __spu_trap_data_seq functions
exit if spu->flags has the SPU_CONTEXT_SWITCH_ACTIVE set. This was
resulting in suprious returns from these functions, as they may be
legitimately called when we have this bit set.

We only use it in these two sanity checks, so this change removes the
flag completely. This fixes hangs in the page-fault path of SPE apps.

Signed-off-by: Dave Airlie <airlied@redhat.com>

On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume.  So restore them unconditionally along with actually restoring pipe B's palette correctly.
Signed-off-by: Dave Airlie <airlied@redhat.com>

On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause
the kernel to disable the interrupt or vblank events to happen at the
wrong time.  So save/restore them properly.
