 "Yes, this is a *LATE* GPIO pull request with fixes for v3.5.

  Grant moved across the planet and accidentally fell off the grid, so
  he asked me to take over the GPIO merges for a while 10 days ago.

  Since then I went over the archives and collected this pile of fixes,
  and pulled two of them from the TI maintainer Kevin Hilman.  Then
  waited for them to at least hit linux-next once or twice."

	Date:   Thu Dec 23 13:43:30 2004 -0500

	    [ACPI] Fix suspend/resume lockup issue
	    by leaving Bus Master Arbitration enabled.

The bug snuck back in in commit 2feec47d4c (ACPICA: ACPI 5: Support
for new FADT SleepStatus, SleepControl registers, 2012-02-14),
presumably by copy/pasting a copy of the code without that fix for the
legacy case.

On affected machines, after that commit, the machine locks up hard on
resume from suspend.  The same fix as seven years ago still works.

bc51b0c22c Revert "of: match by compatible property first"
This reverts commit 107a84e61c.

Meelis Roos reports a regression since 3.5-rc5 that stops Sun Fire V100
and Sun Netra X1 sparc64 machines from booting, hanging after enabling
serial console.  He bisected it to commit 107a84e61c.

Rob Herring explains:
 "The problem is match combinations of compatible plus name and/or type
  fail to match correctly.  I have a fix for this, but given how late it
  is for 3.5 I think it is best to revert this for now.  There could be
  other cases that rely on the current although wrong behavior.  I will
  post an updated version for 3.6."

The helper nfs_fs_mount() will always call nfs4_try_mount with the
mount_info->fill_super argument pointing to nfs_fill_super, which is
NFSv2/v3 only.
Fix is to have nfs4_try_mount replace it with nfs4_fill_super.

dbf0e4c725 PCI: EHCI: fix crash during suspend on ASUS computers
Quite a few ASUS computers experience a nasty problem, related to the
EHCI controllers, when going into system suspend.  It was observed
that the problem didn't occur if the controllers were not put into the
D3 power state before starting the suspend, and commit
151b612847 (USB: EHCI: fix crash during
suspend on ASUS computers) was created to do this.

It turned out this approach messed up other computers that didn't have
the problem -- it prevented USB wakeup from working.  Consequently
commit c2fb8a3fa2 (USB: add
NO_D3_DURING_SLEEP flag and revert 151b612847) was merged; it
reverted the earlier commit and added a whitelist of known good board
names.

Now we know the actual cause of the problem.  Thanks to AceLan Kao for
tracking it down.

According to him, an engineer at ASUS explained that some of their
BIOSes contain a bug that was added in an attempt to work around a
problem in early versions of Windows.  When the computer goes into S3
suspend, the BIOS tries to verify that the EHCI controllers were first
quiesced by the OS.  Nothing's wrong with this, but the BIOS does it
by checking that the PCI COMMAND registers contain 0 without checking
the controllers' power state.  If the register isn't 0, the BIOS
assumes the controller needs to be quiesced and tries to do so.  This
involves making various MMIO accesses to the controller, which don't
work very well if the controller is already in D3.  The end result is
a system hang or memory corruption.

Since the value in the PCI COMMAND register doesn't matter once the
controller has been suspended, and since the value will be restored
anyway when the controller is resumed, we can work around the BIOS bug
simply by setting the register to 0 during system suspend.  This patch
(as1590) does so and also reverts the second commit mentioned above,
which is now unnecessary.

In theory we could do this for every PCI device.  However to avoid
introducing new problems, the patch restricts itself to EHCI host
controllers.

Finally the affected systems can suspend with USB wakeup working
properly.

be2cf20a5a powerpc: More fixes for lazy IRQ vs. idle
Looks like we still have issues with pSeries and Cell idle code
vs. the lazy irq state. In fact, the reset fixes that went upstream
are exposing the problem more by causing BUG_ON() to trigger (which
this patch turns into a WARN_ON instead).

We need to be careful when using a variant of low power state that
has the side effect of turning interrupts back on, to properly set
all the SW & lazy state to look as if everything is enabled before
we enter the low power state with MSR:EE off as we will return with
MSR:EE on. If not, we have a discrepancy of state which can cause
things to go very wrong later on.

This patch moves the logic into a helper and uses it from the
pseries and cell idle code. The power4/970 idle code already got
things right (in assembly even !) so I'm not touching it. The power7
"bare metal" idle code is subtly different and correct. Remains PA6T
and some hypervisor based Cell platforms which have questionable
code in there, but they are mostly dead platforms so I'll fix them
when I manage to get final answers from the respective maintainers
about how the low power state actually works on them.

If the new skb has a different truesize than old one, we can get a

Now we no longer early orphan skbs in dev_hard_start_xmit(), this
probably can lead to fatal bugs.

This patch adds the fix for the same by adding the memory barriers to
ascertain that the all instructions before enabling the Rx or Tx DMA are
completed which involves the proper setting of the ownership bit in DMA
descriptors.

5becfb1df5 kmsg: merge continuation records while printing
In (the unlikely) case our continuation merge buffer is busy, we unfortunately
can not merge further continuation printk()s into a single record and have to
store them separately, which leads to split-up output of these lines when they
are printed.

Add some flags about newlines and prefix existence to these records and try to
reconstruct the full line again, when the separated records are printed.

b48d966526 iwlegacy: don't mess up the SCD when removing a key
When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.

This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.

    iwlwifi: always monitor for stuck queues

    If we only monitor while associated, the following
    can happen:
     - we're associated, and the queue stuck check
       runs, setting the queue "touch" time to X
     - we disassociate, stopping the monitoring,
       which leaves the time set to X
     - almost 2s later, we associate, and enqueue
       a frame
     - before the frame is transmitted, we monitor
       for stuck queues, and find the time set to
       X, although it is now later than X + 2000ms,
       so we decide that the queue is stuck and
       erroneously restart the device

efd821182c rt2x00usb: fix indexes ordering on RX queue kick
On rt2x00_dmastart() we increase index specified by Q_INDEX and on
rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries
between Q_INDEX_DONE and Q_INDEX are those we currently process in the
hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can
submit to the hardware.

According to that fix rt2x00usb_kick_queue(), as we need to submit RX
entries that are not processed by the hardware. It worked before only
for empty queue, otherwise was broken.

Note that for TX queues indexes ordering are ok. We need to kick entries
that have filled skb, but was not submitted to the hardware, i.e.
started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.

From practical standpoint this fixes RX queue stall, usually reproducible
in AP mode, like for example reported here:

10a9109f27 mac80211: destroy assoc_data correctly if assoc fails
If association failed due to internal error (e.g. no
supported rates IE), we call ieee80211_destroy_assoc_data()
with assoc=true, while we actually reject the association.

This results in the BSSID not being zeroed out.

After passing assoc=false, we no longer have to call
sta_info_destroy_addr() explicitly. While on it, move
the "associated" message after the assoc_success check.

17fae1cdea IOMMU fixes for Linux v3.5-rc5
The patches fix several issues in the AMD IOMMU driver, the NVidia SMMU
 driver, and the DMA debug code. The most important fix for the AMD IOMMU
 solves a problem with SR-IOV devices where virtual functions did not
 work with IOMMU enabled. The NVidia SMMU patch fixes a possible sleep
 while spin-lock situation (queued the small fix for v3.5, a better but
 more intrusive fix is coming for v3.6). The DMA debug patches fix a
 possible data corruption issue due to bool vs. u32 usage.

Restore support for partial reads of any size on /proc/kmsg, in case the
supplied read buffer is smaller than the record size.

Some people seem to think is is ia good idea to run:
  $ dd if=/proc/kmsg bs=1 of=...
as a klog bridge.

6bd0405bb4 netfilter: nf_ct_ecache: fix crash with multiple containers, one shutting down
Hans reports that he's still hitting:

BUG: unable to handle kernel NULL pointer dereference at 000000000000027c
IP: [<ffffffff813615db>] netlink_has_listeners+0xb/0x60
PGD 0
Oops: 0000 [#3] PREEMPT SMP
CPU 0

It happens when adding a number of containers with do:

nfct_query(h, NFCT_Q_CREATE, ct);

and most likely one namespace shuts down.

this problem was supposed to be fixed by:
70e9942 netfilter: nf_conntrack: make event callback registration per-netns

Still, it was missing one rcu_access_pointer to check if the callback
is set or not.

06b4ba5295 ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable it
The EHCI driver is not stable enough to be enabled by default.  In v3.5,
it has at least the following problems:

- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
  when no USB devices connected.)

This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.

In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.

b761c9b1f4 cgroup: fix panic in netprio_cgroup
we set max_prioidx to the first zero bit index of prioidx_map in
function get_prioidx.

So when we delete the low index netprio cgroup and adding a new
netprio cgroup again,the max_prioidx will be set to the low index.

when we set the high index cgroup's net_prio.ifpriomap,the function
write_priomap will call update_netdev_tables to alloc memory which
size is sizeof(struct netprio_map) + sizeof(u32) * (max_prioidx + 1),
so the size of array that map->priomap point to is max_prioidx +1,
which is low than what we actually need.

fix this by adding check in get_prioidx,only set max_prioidx when
max_prioidx low than the new prioidx.
