2013-07-03pch_uart: fix a deadlock when pch_uart as consoleLiang Li
commit 384e301e3519599b000c1a2ecd938b533fc15d85 upstream. When we use pch_uart as system console like 'console=ttyPCH0,115200', then 'send break' to it. We'll encounter the deadlock on a cpu/core, with interrupts disabled on the core. When we happen to have all irqs affinity to cpu0 then the deadlock on cpu0 actually deadlock whole system. In pch_uart_interrupt, we have spin_lock_irqsave(&priv->lock, flags) then call pch_uart_err_ir when break is received. Then the call to dev_err would actually call to pch_console_write then we'll run into another spin_lock(&priv->lock), with interrupts disabled. So in the call sequence lead by pch_uart_interrupt, we should be carefully to call functions that will 'print message to console' only in case the uart port is not being used as serial console.

2013-06-20drm/i915: prefer VBT modes for SVDO-LVDS over EDIDDaniel Vetter
commit c3456fb3e4712d0448592af3c5d644c9472cd3c1 upstream. In commit 53d3b4d7778daf15900867336c85d3f8dd70600c Author: Egbert Eich <eich@suse.de> Date: Tue Jun 4 17:13:21 2013 +0200 drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC Egbert Eich fixed a long-standing bug where we simply used a non-working i2c controller to read the EDID for SDVO-LVDS panels. Unfortunately some machines seem to not be able to cope with the mode provided in the EDID. Specifically they seem to not be able to cope with a 4x pixel mutliplier instead of a 2x one, which seems to have been worked around by slightly changing the panels native mode in the VBT so that the dotclock is just barely above 50MHz. Since it took forever to notice the breakage it's fairly safe to assume that at least for SDVO-LVDS panels the VBT contains fairly sane data. So just switch around the order and use VBT modes first. v2: Also add EDID modes just in case, and spell Egbert correctly. v3: Elaborate a bit more about what's going on on Chris' machine.

2013-06-20ath9k: Disable PowerSave by defaultSujith Manoharan
commit 531671cb17af07281e6f28c1425f754346e65c41 upstream. Almost all the DMA issues which have plagued ath9k (in station mode) for years are related to PS. Disabling PS usually "fixes" the user's connection stablility. Reports of DMA problems are still trickling in and are sitting in the kernel bugzilla. Until the PS code in ath9k is given a thorough review, disbale it by default. The slight increase in chip power consumption is a small price to pay for improved link stability.

2013-06-13drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC.Egbert Eich
commit 53d3b4d7778daf15900867336c85d3f8dd70600c upstream. In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC.

2013-06-13drm: fix a use-after-free when GPU acceleration disabledHuacai Chen
commit b7ea85a4fed37835eec78a7be3039c8dc22b8178 upstream. When GPU acceleration is disabled, drm_vblank_cleanup() will free the vblank-related data, such as vblank_refcount, vblank_inmodeset, etc. But we found that drm_vblank_post_modeset() may be called after the cleanup, which use vblank_refcount and vblank_inmodeset. And this will cause a kernel panic. Fix this by return immediately if dev->num_crtcs is zero. This is the same thing that drm_vblank_pre_modeset() does.

The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...

2013-06-07xen/events: Handle VIRQ_TIMER before any other hardirq in event loop.Keir Fraser
commit bee980d9e9642e96351fa3ca9077b853ecf62f57 upstream. This avoids any other hardirq handler seeing a very stale jiffies value immediately after wakeup from a long idle period. The one observable symptom of this was a USB keyboard, with software keyboard repeat, which would always repeat a key immediately that it was pressed. This is due to the key press waking the guest, the key handler immediately runs, sees an old jiffies value, and then that jiffies value significantly updated, before the key is unpressed.

commit e771451c0a831d96a7c14b0ca8a8ec671d98567b upstream. libata honors DMADIR for regular commands, but not for internal commands used (among other) during device initialisation. This makes SATA-host-to-PATA-device bridges based on Silicon Image SiL3611 (such as "Abit Serillel 2") end up disabled when used with an ATAPI device after a few tries. Log output of the bridge being hot-plugged with an ATAPI drive: [ 9631.212901] ata1: exception Emask 0x10 SAct 0x0 SErr 0x40c0000 action 0xe frozen [ 9631.212913] ata1: irq_stat 0x00000040, connection status changed [ 9631.212923] ata1: SError: { CommWake 10B8B DevExch } [ 9631.212939] ata1: hard resetting link [ 9632.104962] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 9632.106393] ata1.00: ATAPI: PIONEER DVD-RW DVR-115, 1.06, max UDMA/33 [ 9632.106407] ata1.00: applying bridge limits [ 9632.108151] ata1.00: configured for UDMA/33 [ 9637.105303] ata1.00: qc timeout (cmd 0xa0) [ 9637.105324] ata1.00: failed to clear UNIT ATTENTION (err_mask=0x5) [ 9637.105335] ata1: hard resetting link [ 9638.044599] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 9638.047878] ata1.00: configured for UDMA/33 [ 9643.044933] ata1.00: qc timeout (cmd 0xa0) [ 9643.044953] ata1.00: failed to clear UNIT ATTENTION (err_mask=0x5) [ 9643.044963] ata1: limiting SATA link speed to 1.5 Gbps [ 9643.044971] ata1.00: limiting speed to UDMA/33:PIO3 [ 9643.044979] ata1: hard resetting link [ 9643.984225] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 9643.987471] ata1.00: configured for UDMA/33 [ 9648.984591] ata1.00: qc timeout (cmd 0xa0) [ 9648.984612] ata1.00: failed to clear UNIT ATTENTION (err_mask=0x5) [ 9648.984619] ata1.00: disabled [ 9649.000593] ata1: hard resetting link [ 9649.939902] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 9649.955864] ata1: EH complete With this patch, the drive enumerates correctly when libata is loaded with atapi_dmadir=1: [ 9891.810863] ata1: exception Emask 0x10 SAct 0x0 SErr 0x40c0000 action 0xe frozen [ 9891.810874] ata1: irq_stat 0x00000040, connection status changed [ 9891.810884] ata1: SError: { CommWake 10B8B DevExch } [ 9891.810900] ata1: hard resetting link [ 9892.762105] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 9892.763544] ata1.00: ATAPI: PIONEER DVD-RW DVR-115, 1.06, max UDMA/33, DMADIR [ 9892.763558] ata1.00: applying bridge limits [ 9892.765393] ata1.00: configured for UDMA/33 [ 9892.786063] ata1: EH complete [ 9892.792062] scsi 0:0:0:0: CD-ROM PIONEER DVD-RW DVR-115 1.06 PQ: 0 ANSI: 5 [ 9892.798455] sr2: scsi3-mmc drive: 12x/12x writer dvd-ram cd/rw xa/form2 cdda tray [ 9892.798837] sr 0:0:0:0: Attached scsi CD-ROM sr2 [ 9892.799109] sr 0:0:0:0: Attached scsi generic sg6 type 5 Based on a patch by Csaba Halász <csaba.halasz@gmail.com> on linux-ide: http://marc.info/?l=linux-ide&m=136121147832295&w=2 tj: minor formatting changes.

2013-06-07USB: io_ti: Fix NULL dereference in chase_port()Wolfgang Frisch
commit 1ee0a224bc9aad1de496c795f96bc6ba2c394811 upstream. The tty is NULL when the port is hanging up. chase_port() needs to check for this. This patch is intended for stable series. The behavior was observed and tested in Linux 3.2 and 3.7.1. Johan Hovold submitted a more elaborate patch for the mainline kernel.

2013-06-07USB: UHCI: fix for suspend of virtual HP controllerAlan Stern
commit 997ff893603c6455da4c5e26ba1d0f81adfecdfc upstream. HP's virtual UHCI host controller takes a long time to suspend (several hundred microseconds), even when no devices are attached. This provokes a warning message from uhci-hcd in the auto-stop case. To prevent this from happening, this patch adds a test to avoid performing an auto-stop when the wait_for_hp quirk flag is set. The controller will still suspend through the normal runtime PM mechanism. And since that pathway includes a 1-ms delay, the slowness of the virtual hardware won't matter.

2013-06-07TTY: Fix tty miss restart after we turn off flow-controlWang YanQing
commit dab73b4eb9ef924a2b90dab84e539076d82b256f upstream. I meet emacs hang in start if I do the operation below: 1: echo 3 > /proc/sys/vm/drop_caches 2: emacs BigFile 3: Press CTRL-S follow 2 immediately Then emacs hang on, CTRL-Q can't resume, the terminal hang on, you can do nothing with this terminal except close it. The reason is before emacs takeover control the tty, we use CTRL-S to XOFF it. Then when emacs takeover the control, it may don't use the flow-control, so emacs hang. This patch fix it.

2013-05-19ACPI / EC: Restart transaction even when the IBF flag setLan Tianyu
commit 28fe5c825f8e15744d04c7c1b8df197950923ecd upstream. The EC driver works abnormally with IBF flag always set. IBF means "The host has written a byte of data to the command or data port, but the embedded controller has not yet read it". If IBF is set in the EC status and not cleared, this will cause all subsequent EC requests to fail with a timeout error. Change the EC driver so that it doesn't refuse to restart a transaction if IBF is set in the status. Also increase the number of transaction restarts to 5, as it turns out that 2 is not sufficient in some cases. This bug happens on several different machines (Asus V1S, Dell Latitude E6530, Samsung R719, Acer Aspire 5930G, Sony Vaio SR19VN and others).

2013-05-19drbd: fix for deadlock when using automatic split-brain-recoveryPhilipp Reisner
commit 7c689e63a847316c1b2500f86891b0a574ce7e69 upstream. With an automatic after split-brain recovery policy of "after-sb-1pri call-pri-lost-after-sb", when trying to drbd_set_role() to R_SECONDARY, we run into a deadlock. This was first recognized and supposedly fixed by 2009-06-10 "Fixed a deadlock when using automatic split brain recovery when both nodes are" replacing drbd_set_role() with drbd_change_state() in that code-path, but the first hunk of that patch forgets to remove the drbd_set_role(). We apparently only ever tested the "two primaries" case.

commit ce11ff5e5963e441feb591e76278528f876c332d upstream. Control of receive descriptor must not be returned to ethernet chipset before vlan tag processing is done. VLAN tag receive word is now reset both in normal and error path.
