target: fix regression with dev_link_magic in target_fabric_port_link

2013-02-04T00:24:42+00:00

This is to fix a regression that only affect the stable (not for the mainline)
that the stable commit fdf9d86 was incorrectly placed dev->dev_link_magic check
before the *dev assignment in target_fabric_port_link() due to fuzzy automatically
context adjustment during the back-porting.

iommu/intel: disable DMAR for g4x integrated gfx

2013-02-04T00:24:41+00:00

commit 9452618e7462181ed9755236803b6719298a13ce upstream.

DMAR support on g4x/gm45 integrated gpus seems to be totally busted.
So don't bother, but instead disable it by default to allow distros to
unconditionally enable DMAR support.

v2: Actually wire up the right quirk entry, spotted by Adam Jackson.

Note that according to intel marketing materials only g45 and gm45
support DMAR/VT-d. So we have reports for all relevant gen4 pci ids by
now. Still, keep all the other gen4 ids in the quirk table in case the
marketing stuff confused me again, which would not be the first time.

ath9k: fix double-free bug on beacon generate failure

2013-02-04T00:24:41+00:00

commit 1adb2e2b5f85023d17eb4f95386a57029df27c88 upstream.

When the next beacon is sent, the ath_buf from the previous run is reused.
If getting a new beacon from mac80211 fails, bf->bf_mpdu is not reset, yet
the skb is freed, leading to a double-free on the next beacon tx attempt,
resulting in a system crash.

ath9k: do not link receive buffers during flush

2013-02-04T00:24:41+00:00

commit a3dc48e82bb146ef11cf75676c8410c1df29b0c4 upstream.

On AR9300 the rx FIFO needs to be empty during reset to ensure that no
further DMA activity is generated, otherwise it might lead to memory
corruption issues.

ath9k_htc: Fix memory leak

2013-02-04T00:24:41+00:00

commit 0981c3b24ef664f5611008a6e6d0622fac6d892b upstream.

SKBs that are allocated in the HTC layer do not have callbacks
registered and hence ended up not being freed, Fix this by freeing
them properly in the TX completion routine.

brcmsmac: increase timer reference count for new timers only

2013-02-04T00:24:41+00:00

commit a1fe52801a992e590cdaee2fb47a94bac9b5da90 upstream.

On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.

We do not correctly change interface type when switching from
IBSS mode to STA mode, that results in microcode errors.

IOMMU, AMD Family15h Model10-1Fh erratum 746 Workaround

2013-02-04T00:24:40+00:00

commit 318fe782539c4150d1b8e4e6c9dc3a896512cb8a upstream.

The IOMMU may stop processing page translations due to a perceived lack
of credits for writing upstream peripheral page service request (PPR)
or event logs. If the L2B miscellaneous clock gating feature is enabled
the IOMMU does not properly register credits after the log request has
completed, leading to a potential system hang.

BIOSes are supposed to disable L2B micellaneous clock gating by setting
L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This
patch corrects that for those which do not enable this workaround.
