2011-05-14Revert "libata: ahci_start_engine compliant to AHCI spec"Tejun Heo1-21/+0
This reverts commit 270dac35c26433d06a89150c51e75ca0181ca7e4. The commits causes command timeouts on AC plug/unplug. It isn't yet clear why. As the commit was for a single rather obscure controller, revert the change for now. The problem was reported and bisected by Gu Rui in bug#34692. https://bugzilla.kernel.org/show_bug.cgi?id=34692 Also, reported by Rafael and Michael in the following thread. http://thread.gmane.org/gmane.linux.kernel/1138771 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Gu Rui <chaos.proton@gmail.com> Reported-by: Rafael J.

2011-05-13drm/i915: Revert i915.semaphore=1 default from i915 mergeAndy Lutomirski1-1/+1
My Q67 / i7-2600 box has rev09 Sandy Bridge graphics. It hangs instantly when GNOME loads and it hangs so hard the reset button doesn't work. Setting i915.semaphore=0 fixes it. Semaphores were disabled in a1656b9090f7 ("drm/i915: Disable GPU semaphores by default") in 2.6.38 but were then re-enabled (by mistake?) by the merge 47ae63e0c2e5 ("Merge branch 'drm-intel-fixes' into drm-intel-next"). (It's worth noting that the offending change is i915_drv.c, which was not marked as a conflict - although a 'git show --cc' on the merge does show that neither parent had it set to 1) Signed-off-by: Andy Lutomirski <luto@mit.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-05-13bonding,llc: Fix structure sizeof incompatibility for some PDUsVitalii Demianets1-5/+5
With some combinations of arch/compiler (e.g. arm-linux-gcc) the sizeof operator on structure returns value greater than expected. In cases when the structure is used for mapping PDU fields it may lead to unexpected results (such as holes and alignment problems in skb data). __packed prevents this undesired behavior.

2011-05-12fbmem: make read/write/ioctl use the frame buffer at open timeLinus Torvalds1-16/+34
read/write/ioctl on a fbcon file descriptor has traditionally used the fbcon not when it was opened, but as it was at the time of the call. That makes no sense, but the lack of sense is much more obvious now that we properly ref-count the usage - it means that the ref-counting doesn't actually protect operations we do on the frame buffer. This changes it to look at the fb_info that we got at open time, but in order to avoid using a frame buffer long after it has been unregistered, we do verify that it is still current, and return -ENODEV if not.

2011-05-12fbcon: add lifetime refcount to opened frame buffersLinus Torvalds1-10/+46
This just adds the refcount and the new registration lock logic. It does not (for example) actually change the read/write/ioctl routines to actually use the frame buffer that was opened: those function still end up alway susing whatever the current frame buffer is at the time of the call. Without this, if something holds the frame buffer open over a framebuffer switch, the close() operation after the switch will access a fb_info that has been free'd by the unregistering of the old frame buffer. (The read/write/ioctl operations will normally not cause problems, because they will - illogically - pick up the new fbcon instead. But a switch that happens just as one of those is going on might see problems too, the window is just much smaller: one individual op rather than the whole open-close sequence.) This use-after-free is apparently fairly easily triggered by the Ubuntu 11.04 boot sequence.

2011-05-12sfc: Always map MCDI shared memory as uncacheableBen Hutchings3-23/+53
We enabled write-combining for memory-mapped registers in commit 65f0b417dee94f779ce9b77102b7d73c93723b39, but inhibited it for the MCDI shared memory where this is not supported. However, write-combining mappings also allow read-reordering, which may also be a problem. I found that when an SFC9000-family controller is connected to an Intel 3000 chipset, and write-combining is enabled, the controller stops responding to PCIe read requests during driver initialisation while the driver is polling for completion of an MCDI command. This results in an NMI and system hang. Adding read memory barriers between all reads to the shared memory area appears to reduce but not eliminate the probability of this. We have not yet established whether this is a bug in our BIU or in the PCIe bridge. For now, work around by mapping the shared memory area separately.

during suspend/S3 state drv_flush is called from mac80211 irrespective of interface count. In ath9k we queue a work in ath9k_flush which we expect to be cancelled in the drv_stop call back. during suspend process mac80211 calls drv_stop only when the interface count(local->count) is non-zero. unfortunately when the network manager is enabled, drv_flush is called while drv_stop is not called as local->count reaches '0'. So fix this by simply checking for the device presence in the drv_flush call back in the driver before queueing work or anything else. this patch fixes the following WARNING Call Trace: [<c014c6e2>] warn_slowpath_common+0x72/0xa0 [<fc133f99>] ? ieee80211_can_queue_work+0x39/0x50 [mac80211] [<fc133f99>] ? ieee80211_can_queue_work+0x39/0x50 [mac80211] [<c014c75b>] warn_slowpath_fmt+0x2b/0x30 [<fc133f99>] ieee80211_can_queue_work+0x39/0x50 [mac80211] [<fc134ed1>] ieee80211_queue_delayed_work+0x21/0x50 [mac80211] [<fc1e5b22>] ath_tx_complete_poll_work+0xb2/0x100 [ath9k] [<c016399e>] run_workqueue+0x8e/0x150 [<fc1e5a70>] ? ath_tx_complete_poll_work+0x0/0x100 [ath9k] [<c0163ae4>] worker_thread+0x84/0xe0 [<c0167a60>] ? autoremove_wake_function+0x0/0x50 [<c0163a60>] ? worker_thread+0x0/0xe0 [<c01677d4>] kthread+0x74/0x80 [<c0167760>] ? kthread+0x0/0x80 [<c0104087>] kernel_thread_helper+0x7/0x10 ---[ end trace 2aff81010df9215b ]--- Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: Mohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: John W.

2011-05-09drm/i915/lvds: Only act on lid notify when the device is onAlex Williamson1-0/+3
If we're using vga switcheroo, the device may be turned off and poking it can return random state. This provokes an OOPS fixed separately by 8ff887c847 (drm/i915/dp: Be paranoid in case we disable a DP before it is attached). Trying to use and respond to events on a device that has been turned off by the user is in principle a silly thing to do.

Despite the fixes in 548f245ba6a31 (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c (drm/i915: cleanup per-pipe reg usage). This was preventing us from correctly determining the mode the BIOS left the panel in for machines that neither have an OpRegion nor access to the VBT, (e.g. the EeePC 700).
