70f289db31 fbdev: bf537-lq035: add missing blacklight properties type
Seems this new field was missed, probably due to this driver being merged
around the time this new backlight field was being added.  At any rate,
initial the type field to avoid ugly WARN() dumps.

2e4ceec4ed drivers/net/can/flexcan.c: add missing clk_put
The failed_get label is used after the call to clk_get has succeeded, so it
should be moved up above the call to clk_put.

The failed_req labels doesn't do anything different than failed_get, so
delete it.

6979d5dd96 net: dm9000: Get the chip in a known good state before enabling interrupts
Currently the DM9000 driver requests the primary interrupt before it
resets the chip and puts it into a known good state. This means that if
the chip is asserting interrupt for some reason we can end up with a
screaming IRQ that the interrupt handler is unable to deal with. Avoid
this by only requesting the interrupt after we've reset the chip so we
know what state it's in.

This started manifesting itself on one of my boards in the past month or
so, I suspect as a result of some core infrastructure changes removing
some form of mitigation against bad behaviour here, even when things boot
it seems that the new code brings the interface up more quickly.

a3bcc23e89 af-packet: Add flag to distinguish VID 0 from no-vlan.
Currently, user-space cannot determine if a 0 tcp_vlan_tci
means there is no VLAN tag or the VLAN ID was zero.

Add flag to make this explicit.  User-space can check for
TP_STATUS_VLAN_VALID || tp_vlan_tci > 0, which will be backwards
compatible. Older could would have just checked for tp_vlan_tci,
so it will work no worse than before.

Commit a321cedb12 excludes CPU models 0xe, 0xf,
0x16, and 0x1a from TjMax temperature adjustment, even though several of those
CPUs are known to have TiMax other than 100 degrees C, and even though the code
in adjust_tjmax() explicitly handles those CPUs and points to a Web document
listing several of the affected CPU IDs.

Reinstate original TjMax adjustment if TjMax can not be determined using the
IA32_TEMPERATURE_TARGET register.

1fa7b6a29c Revert "mm: fail GFP_DMA allocations when ZONE_DMA is not configured"
This reverts commit a197b59ae6.

As rmk says:
 "Commit a197b59ae6 (mm: fail GFP_DMA allocations when ZONE_DMA is not
  configured) is causing regressions on ARM with various drivers which
  use GFP_DMA.

  The behaviour up until now has been to silently ignore that flag when
  CONFIG_ZONE_DMA is not enabled, and to allocate from the normal zone.
  However, as a result of the above commit, such allocations now fail
  which causes drivers to fail.  These are regressions compared to the
  previous kernel version."

so just revert it.

Jens' back-merge commit 698567f3fa ("Merge commit 'v2.6.39' into

 - 9fd097b149 ("block: unexport DISK_EVENT_MEDIA_CHANGE for
   legacy/fringe drivers")

 - 7eec77a181 ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd
   and ide-cd")

because of conflicts with the "g->flags" updates near-by by commit
d4dc210f69 ("block: don't block events on excl write for non-optical
devices")

As a result, we re-introduced the hanging behavior due to infinite disk
media change reports.

Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't
do them to hide merge conflicts from me - especially as I'm likely
better at merging them than you are, since I do so many merges.

6e3ea0e711 [media] v4l: Fix media_entity_to_video_device macro argument name
The name 'entity' is used twice in the macro body, once as the macro
argument, and once as a structure field name. This breaks compilation if
the macro is called with its argument not named 'entity'.

Fix this by renaming the macro argument '__e'. This should avoid
namespace clashes.

70e535d1e5 intel-iommu: Fix off-by-one in RMRR setup
We were mapping an extra byte (and hence usually an extra page):
iommu_prepare_identity_map() expects to be given an 'end' argument which
is the last byte to be mapped; not the first byte *not* to be mapped.

1fcecf281b ARM: OMAP4: MMC: increase delay for pbias
4 micro seconds is not enough for PBIAS if MMC regulator is
enabled from MMC regulator OFF.
Increase the delay for PBIAS to stabilize.
Wait for PBIAS and timeout if not.

Resolves MMC/SD failure on OMAP4
"Pbias Voltage is not same as LDO"

8519dc4401 intel-iommu: Add domain check in domain_remove_one_dev_info
The comment in domain_remove_one_dev_info() states "No need to compare
PCI domain; it has to be the same". But for the si_domain that isn't
going to be true, as it consists of all the PCI devices that are
identity mapped thus multiple PCI domains can be in si_domain.  The
code needs to validate the PCI domain too.

825507d6d0 intel-iommu: Remove Host Bridge devices from identity mapping
When using the 1:1 (identity) PCI DMA remapping, PCI Host Bridge devices
that do not use the IOMMU causes a kernel panic.  Fix that by not
inserting those devices into the si_domain.

1c9fc3d11b intel-iommu: Dont cache iova above 32bit
Mike Travis and Mike Habeck reported an issue where iova allocation
would return a range that was larger than a device's dma mask.

https://lkml.org/lkml/2011/3/29/423

The dmar initialization code will reserve all PCI MMIO regions and copy
those reservations into a domain specific iova tree.  It is possible for
one of those regions to be above the dma mask of a device.  It is typical
to allocate iovas with a 32bit mask (despite device's dma mask possibly
being larger) and cache the result until it exhausts the lower 32bit
address space.  Freeing the iova range that is >= the last iova in the
lower 32bit range when there is still an iova above the 32bit range will
corrupt the cached iova by pointing it to a region that is above 32bit.
If that region is also larger than the device's dma mask, a subsequent
allocation will return an unusable iova and cause dma failure.

Simply don't cache an iova that is above the 32bit caching boundary.
