For machines with IBFT 1.03 do scan the ACPI table for 'iBFT'
or for 'IBFT'. If the machine is in UEFI mode, only do the ACPI

  ALSA: hda - fix DG45ID SPDIF output

After commit 1f36f774 ("Switch !O_CREAT case to use of do_last()") in
2.6.34-rc1 autofs direct mounts stopped working.  This is caused by
current->link_count being 0 when ->follow_link() is called from
do_filp_open().

I can't work out why this hasn't been seen before Als patch series.

This patch removes the autofs dependence on current->link_count.

commit 672917dc ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.

Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis.  The fix is
simple, zero the variable after doing the work from the previous idle.

During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.

Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().

Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down.  Device failure/removal
etc are still recorded on spares.

However commit 51d5668c broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:

   This means that the alignment between 'odd/even' and
    'clean/dirty' might take a little longer to attain,

how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.

So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately.  There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update).  We just piggy-back on that.

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.
