autofs4-2.6.34-rc1 - fix link_count usage
After commit
1f36f774b2 ("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

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.

cpuidle: Fix incorrect optimization
commit
672917dcc78 ("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.

HID: fix suspend crash by moving initializations earlier
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().

md: restore ability of spare drives to spin down.
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
51d5668cb2e3fd1827a55 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.

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

V4L/DVB: gspca - stv06xx: Remove the 046d:08da from the stv06xx driver
The 046d:08da usb id shouldn't be associated with the stv06xx driver as they're
not compatible with each other.
This fixes a bug where Quickcam Messenger cams fail to use its proper driver
(gspca-zc3xx), rendering the camera inoperable.

rcu: create rcu_my_thread_group_empty() wrapper
Some RCU-lockdep splat repairs need to know whether they are running

commit therefore introduces a rcu_my_thread_group_empty() wrapper that

C implementation do not need aligned end address and ASM code do aligned

4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address.
Because end address is compound from start + size, end address is the first address
which is exclude.
Here is the corresponding code which describe it.
+ int align = ~(line_length - 1);
+ end = ((end & align) == end) ? end - line_length : end & align;

PNP: don't check for conflicts with bridge windows
With
fa35b4926, I broke a lot of PNP resource assignment. That commit made
PNPACPI include bridge windows as PNP resources, and PNP resource assignment
treats any enabled overlapping PNP resources as conflicts. Since PCI host
bridge windows typically include most of the I/O port space, this makes PNP
port assigments fail.
The PCI host bridge driver will eventually use those PNP window resources,
so we should make PNP ignore them when checking for conflicts.

ACPI: DMI init_set_sci_en_on_resume for multiple Lenovo ThinkPads
Multiple Lenovo ThinkPad models with Intel Core i5/i7 CPUs can
successfully suspend/resume once, and then hang on the second s/r
cycle.
We got confirmation that this was due to a BIOS defect. The BIOS
did not properly set SCI_EN coming out of S3. The BIOS guys
hinted that The Other Leading OS ignores the fact that hardware
owns the bit and sets it manually.
In any case, an existing DMI table exists for machines where this
defect is a known problem. Lenovo promise to fix their BIOS, but
for folks who either won't or can't upgrade their BIOS, allow
Linux to workaround the issue.
https://bugzilla.kernel.org/show_bug.cgi?id=15407
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/532374
Confirmed by numerous testers in the launchpad bug that using
acpi_sleep=sci_force_enable fixes the issue. We add the machines
to acpisleep_dmi_table[] to automatically enable this workaround.

[SCSI] Retry commands with UNIT_ATTENTION sense codes to fix ext3/ext4 I/O error
There's nastyness in the way we currently handle barriers (and
discards): They're effectively filesystem commands, but they get
processed as BLOCK_PC commands. Unfortunately BLOCK_PC commands are
taken by SCSI to be SG_IO commands and the issuer expects to see and
handle any returned errors, however trivial. This leads to a huge
problem, because the block layer doesn't expect this to happen and any
trivially retryable error on a barrier causes an immediate I/O error
to the filesystem.
The only real way to hack around this is to take the usual class of
offending errors (unit attentions) and make them all retryable in the
case of a REQ_HARDBARRIER. A correct fix would involve a rework of
the entire block and SCSI submit system, and so is out of scope for a
quick fix.

[SCSI] Enable retries for SYNCRONIZE_CACHE commands to fix I/O error
Some arrays are giving I/O errors with ext3 filesystems when
SYNCHRONIZE_CACHE gets a UNIT_ATTENTION. What is happening is that
these commands have no retries, so the UNIT_ATTENTION causes the
barrier to fail. We should be enable retries here to clear any
transient error and allow the barrier to succeed.
