James Hogan 5698c50d9d metag: Internal and external irqchips
Meta core internal interrupts (from HWSTATMETA and friends) are vectored
onto the TR1 core trigger for the current thread. This is demultiplexed
in irq-metag.c to individual Linux IRQs for each internal interrupt.

External SoC interrupts (from HWSTATEXT and friends) are vectored onto
the TR2 core trigger for the current thread. This is demultiplexed in
irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt.
The external irqchip has devicetree bindings for configuring the number
of irq banks and the type of masking available.

James Hogan a2c5d4ed92 metag: Time keeping
Add time keeping code for metag. Meta hardware threads have 2 timers.
The background timer (TXTIMER) is used as a free-running time base, and
the interrupt timer (TXTIMERI) is used for the timer interrupt. Both
counters traditionally count at approximately 1MHz.

Mauro Carvalho Chehab ac89758697 Revert "[media] dvb_frontend: return -ENOTTY for unimplement IOCTL"
As reported by Klaus Schmidinger:
 "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a
  device (using stb0899).  After this call I check 'errno' for
  EOPNOTSUPP to determine whether this device supports this call.  This
  used to work just fine, until a few months ago I noticed that my
  devices using stb0899 didn't display their signal quality in VDR's OSD
  any more.  After further investigation I found that
  ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but
  rather ENOTTY.  And since I stop getting the signal quality in case
  any unknown errno value appears, this broke my signal quality query
  function."

While the changes reflect what is there at:

  http://comments.gmane.org/gmane.linux.kernel/1235728

it does cause regression on userspace.  So, revert it to stop the
damage.

This reverts commit 177ffe506c ("[media] dvb_frontend: return -ENOTTY

Tomi Valkeinen 91e83ffd6d omapdrm: fix the dependency to omapdss
omapdrm uses "select" in Kconfig to enable omapdss. This doesn't work
correctly, as "select" forces omapdss to be enabled in the config even
if it normally could not be enabled because of missing Kconfig
dependencies.

This causes a build break on ARM, when using allyesconfig:

drivers/video/omap2/dss/dss.c: In function 'dss_calc_clock_div':
drivers/video/omap2/dss/dss.c:572:20: error: 'CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK' undeclared (first use in this function)
drivers/video/omap2/dss/dss.c:572:20: note: each undeclared identifier is reported only once for each function it appears in

Instead of using select, this patch changes omapdrm to use "depend
on".

commit 195e672a76
   OMAPDSS: DPI: Remove cpu_is_xxxx checks

made the mistake of assuming that cpu_is_omap34xx() is exclusive of
other cpu_is_* predicates whereas it includes cpu_is_omap3630().

So on an omap3630, code that was previously enabled by
  if (cpu_is_omap34xx())
is now disabled as
  dss_has_feature(FEAT_DPI_USES_VDDS_DSI)
fails.

So add FEAT_DPI_USES_VDDS_DSI to omap3630_dss_feat_list.

Rafael J. Wysocki 249bfb83cf PCI/PM: Clean up PME state when removing a device
Devices are added to pci_pme_list when drivers use pci_enable_wake()
or pci_wake_from_d3(), but they aren't removed from the list unless
the driver explicitly disables wakeup.  Many drivers never disable
wakeup, so their devices remain on the list even after they are
removed, e.g., via hotplug.  A subsequent PME poll will oops when
it tries to touch the device.

This patch disables PME# on a device before removing it, which removes
the device from pci_pme_list.  This is safe even if the device never
had PME# enabled.

This oops can be triggered by unplugging a Thunderbolt ethernet adapter
on a Macbook Pro, as reported by Daniel below.

Commit e7e034e18a ("drivers/rtc/rtc-pl031.c: fix the missing operation

The bit that is being poked as "clockwatch" enable bit for the ST
variants does the work of bit 0 on this variant.  Bit 0 is used for a
clock divider on the ST variants, and setting it to 1 will affect
timekeeping in a very bad way.

====================
Here is another handful of late-breaking fixes intended for the 3.8
stream...  Hopefully the will still make it! :-)

There are three mac80211 fixes pulled from Johannes:

"Here are three fixes still for the 3.8 stream, the fix from Cong Ding
for the bad sizeof (Stephen Hemminger had pointed it out before but I'd
promptly forgotten), a mac80211 managed-mode channel context usage fix
where a downgrade would never stop until reaching non-HT and a bug in
the channel determination that could cause invalid channels like HT40+
on channel 11 to be used."

Also included is a mwl8k fix that avoids an oops when using mwl8k
devices that only support the 5 GHz band.

Please let me know if there are problems!

Alexander Duyck 96be80abaf ixgbe: Only set gso_type to SKB_GSO_TCPV4 as RSC does not support IPv6
The original fix that was applied for setting gso_type required more change
than necessary because it was assumed ixgbe does RSC on IPv6 frames and this
is not correct.  RSC is only supported with IPv4/TCP frames only.  As such we
can simplify the fix and avoid the unnecessary move of eth_type_trans.

The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix
to one line that sets gso_type to TCPV4 if the frame is RSC.

Jerome Glisse de0babd60d drm/radeon: enforce use of radeon_get_ib_value when reading user cmd
When ever parsing cmd buffer supplied by userspace we need to use
radeon_get_ib_value rather than directly accessing the ib as the user
cmd might not yet be copied into the ib thus the parser might read
value that does not correspond to what user is sending and possibly
allowing user to send malicious command undected.

Jonas Gorski d786f67e5c mwl8k: fix band for supported channels
The band field for the supported channels were left unpopulated, making
them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels.

This resulted in null pointer accesses if anything tries to access
wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since
wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

Heiko Carstens ab54ee80aa atm/iphase: rename fregt_t -> ffreg_t
We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the
iphase atm device driver, which causes the compile error below.
Unfortunately the s390 typedef can't be renamed, since it's a user visible api,
nor can I change the include order in s390 code to avoid the conflict.

So simply rename the iphase typedef to a new name. Fixes this compile error:

David S. Miller 0c35565b46 Merge branch 'netback'
Ian Campbell says:

====================
The Xen netback implementation contains a couple of flaws which can
allow a guest to cause a DoS in the backend domain, potentially
affecting other domains in the system.

CVE-2013-0216 is a failure to sanity check the ring producer/consumer
pointers which can allow a guest to cause netback to loop for an
extended period preventing other work from occurring.

CVE-2013-0217 is a memory leak on an error path which is guest
triggerable.

The following series contains the fixes for these issues, as previously
included in Xen Security Advisory 39:
http://lists.xen.org/archives/html/xen-announce/2013-02/msg00001.html

Changes in v2:
 - Typo and block comment format fixes
 - Added stable Cc

Ian Campbell 48856286b6 xen/netback: shutdown the ring if it contains garbage.
A buggy or malicious frontend should not be able to confuse netback.
If we spot anything which is not as it should be then shutdown the
device and don't try to continue with the ring in a potentially
hostile state. Well behaved and non-hostile frontends will not be
penalised.

As well as making the existing checks for such errors fatal also add a
new check that ensures that there isn't an insane number of requests
on the ring (i.e. more than would fit in the ring). If the ring
contains garbage then previously is was possible to loop over this
insane number, getting an error each time and therefore not generating
any more pending requests and therefore not exiting the loop in
xen_netbk_tx_build_gops for an externded period.

Also turn various netdev_dbg calls which no precipitate a fatal error
into netdev_err, they are rate limited because the device is shutdown
afterwards.

This fixes at least one known DoS/softlockup of the backend domain.

Daniel Vetter ff7c60c580 drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd try
This fixes up

commit e8e89622ed
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Dec 18 22:25:11 2012 +0100

    drm/ttm: fix fence locking in ttm_buffer_object_transfer

which leaves behind a might_sleep in atomic context, since the
fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix
is to revert the above commit and only take the lock where we need it,
around the call to ->sync_obj_ref.

v2: Fixup things noticed by Maarten Lankhorst:
- Brown paper bag locking bug.
- No need for kzalloc if we clear the entire thing on the next line.
- check for bo->sync_obj (totally unlikely race, but still someone
  else could have snuck in) and clear fbo->sync_obj if it's cleared
  already.

Don't access uninitialized work-queue when removing device.
The work queue is initialized only if the device multi-queue.
So don't call cancel_work unless this is a multi-queue device.
