90bf80a1f1 ARM: ixp4xx bug fixes
These were originally prepared by Krzysztof Halasa but not submitted
 in time for v3.7 due to some confusion about how ixp4xx patches should
 be handled. Jason Cooper thankfully offered to help out sending the
 patches upstream through arm-soc now, but given the timing, we could

1430e17844 drivers/rtc/rtc-tps65910.c: fix invalid pointer access on _remove()
The tps65910_rtc data is registered as the platform driver data in
_probe(= ).  Therefore the tps65910_rtc should be used on unregistering
the rtc device.  And device pointer should be retrieved from the
platform_device structure.

This patch fixes the below oops:

 "Some more fixes trickled in over the past few days:

   4) Fix a memory leak and an error return flub in SCTP and IRDA
      triggerable by userspace.  Fix from Tommi Rantala and found by the

   9) Netfilter IPSET's netlink code can overrun a string buffer because
      it's not properly limited to IFNAMSIZ.  Fix from Florian Westphal.

  10) PCAN USB driver sets wrong timestamp in SKB, from Oliver Hartkopp.

  11) Make sure the RX ifindex always has a valid value in the CAN BCM

82b212f400 Revert "mm: remove __GFP_NO_KSWAPD"
With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction
based on failures" reverted, Zdenek Kabelac reported the following

  Hmm,  so it's just took longer to hit the problem and observe
  kswapd0 spinning on my CPU again - it's not as endless like before -
  but still it easily eats minutes - it helps to	turn off  Firefox
  or TB  (memory hungry apps) so kswapd0 stops soon - and restart
  those apps again.  (And I still have like >1GB of cached memory)

  kswapd0         R  running task        0    30      2 0x00000000
  Call Trace:
    preempt_schedule+0x42/0x60
    _raw_spin_unlock+0x55/0x60
    put_super+0x31/0x40
    drop_super+0x22/0x30
    prune_super+0x149/0x1b0
    shrink_slab+0xba/0x510

The sysrq+m indicates the system has no swap so it'll never reclaim
anonymous pages as part of reclaim/compaction.  That is one part of the
problem but not the root cause as file-backed pages could also be
reclaimed.

The likely underlying problem is that kswapd is woken up or kept awake
for each THP allocation request in the page allocator slow path.

If compaction fails for the requesting process then compaction will be
deferred for a time and direct reclaim is avoided.  However, if there
are a storm of THP requests that are simply rejected, it will still be
the the case that kswapd is awake for a prolonged period of time as
pgdat->kswapd_max_order is updated each time.  This is noticed by the
main kswapd() loop and it will not call kswapd_try_to_sleep().  Instead
it will loopp, shrinking a small number of pages and calling
shrink_slab() on each iteration.

The temptation is to supply a patch that checks if kswapd was woken for
THP and if so ignore pgdat->kswapd_max_order but it'll be a hack and not
backed up by proper testing.  As 3.7 is very close to release and this
is not a bug we should release with, a safer path is to revert "mm:
remove __GFP_NO_KSWAPD" for now and revisit it with the view to ironing
out the balance_pgdat() logic in general.

c9faaa09e2 can: peak_usb: fix hwtstamp assignment
The skb->tstamp is set to the hardware timestamp when available in the USB
urb message. This leads to user visible timestamps which contain the 'uptime'
of the USB adapter - and not the usual system generated timestamp.

Fix this wrong assignment by applying the available hardware timestamp to the
skb_shared_hwtstamps data structure - which is intended for this purpose.

it again until it is stable.

    drm/i915: disable rc6 on ilk when vt-d is enabled

Note: The situation around the gen4/5 gpu hangs that cropped up in 3.7
is rather strange. Most useful bisects have lead to

commit 6c085a728c
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Aug 20 11:40:46 2012 +0200

    drm/i915: Track unbound pages

or even later commits that affect the gem bo recycling, which all is
way past the point where we re-enabled rc6. But somehow
reverting/disabling those commits doesn't help, but disabling rc6 at
least helps for many hangs on ilk. Obviously it doesn't change
anything at all on gen4, and there are still strange issues left on
gen5 (which we unfortunately can't readily reproduce).

Also, the error_state signature of the hangs which can be fixed with
this patch look remarkably different to those which seem to be
unaffected by the rc6 settings: The rc6 hangs are in the ring,
somewhere in the MI_FLUSH/PIPE_CONTROL sequence to make ilk coherent,
wheras all the other hangs tend to be at a random point in the middle
of the user batch. So it could also be that we have different issues.

Until we grow more clue, this at least helps some users.

35f95d228e Most important part of this is that it fixes a regression in Samsung
NAND chip detection, introduced by some rework which went into 3.7. The
 initial fix wasn't quite complete, so it's in two parts. In fact the
 first part is committed twice (Artem committed his own copy of the same
 patch) and I've merged Artem's tree into mine which already had that fix.
 
 I'd have recommitted that to make it somewhat cleaner, but figured by
 this point in the release cycle it was better to merge *exactly* the
 commits which have been in linux-next.
 
 If I'd recommitted, I'd also omit the sparse warning fix. But it's there,
 and it's harmless — just marking one function as 'static' in onenand code.

a7227a0faa PM / QoS: fix wrong error-checking condition
dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.

Hi Jens,

Another tiny patch.

Removed __packed before the struct smart_attr and added __packed at end of
the structure to fix padding issue.

11cfb6ff73 aoe: avoid running request handler on plugged queue
Calling the request handler directly on a plugged queue defeats
the performance improvements provided by the plugging mechanism.
Use the __blk_run_queue function instead of calling the request
handler directly, so that we don't interfere with the block
layer's ability to plug the queue.

7c5d62388e mtip32xx: fix shift larger than type warning
If we're building a 32-bit kernel and CONFIG_LBADF isn't set,
sector_t is 32-bits wide. The shifts by 32 and 40 are thus
larger than we support.

Cast the sector offset to a u64 to avoid these warnings.

eda4531492 mtip32xx: Fix to make lba address correct in big-endian systems
Earlier lba address was assigned directly to lba_low and lba_low_ex,
which would result in a different number (bytes reversed) in
big-endian systems. Now assigning lba address byte-by-byte to fis.

3208795e61 mtip32xx: fix potential crash on SEC_ERASE_UNIT
The mtip driver lifted this code from elsewhere and then added a special
handling check for SEC_ERASE_UNIT. If the caller tries to do a security
erase but passes no output data for the command then outbuf is not
allocated and the driver duly explodes.

a8c32a5c98 dm: fix deadlock with request based dm and queue request_fn recursion
Request based dm attempts to re-run the request queue off the
request completion path. If used with a driver that potentially does
end_io from its request_fn, we could deadlock trying to recurse
back into request dispatch. Fix this by punting the request queue
run to kblockd.

Tested to fix a quickly reproducible deadlock in such a scenario.

9a30a61f35 drm/i915: do not default to 18 bpp for eDP if missing from VBT

Date:   Wed Jan 13 11:19:52 2010 +0800

    drm/i915: parse eDP panel color depth from VBT block

originally introduced parsing bpp for eDP from VBT, with a default of 18
bpp if the eDP BIOS data block is not present. Turns out that default seems
to break the Macbook Pro with retina display, as noted in

commit 4344b813f1
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Aug 10 11:10:20 2012 +0200

    drm/i915: ignore eDP bpc settings from vbt

Since we can't ignore bpc settings from VBT completely after all, get rid
of the default. Do not clamp eDP to 18 bpp by default if the eDP BDB is
missing from VBT.

a2d2eda7bf SCSI fixes on 20121122
This is a set of four bug fixes.  The isci one is an obvious thinko (using
 request buffer instead of response buffer) which causes a command to fail.
 The three others are DIF/DIX updates which are required because they're part
 of a series of ten patches, the other seven of which went into the block layer
 during the merge window meaning our current DIF/DIX implementation is broken
 without these three.
