2010-02-09drm/nouveau: Fix fbcon on mixed pre-NV50 + NV50 multicard.Marcin Kościelnicki
We used single shared fbops struct and patched it at fb init time with pointers to the right variant. On mixed multicard, this meant that it was either sending NV50-style commands to all cards, or NV04-style commands to all cards.

2010-02-09drm/nouveau: call ttm_bo_wait with the bo lock held to prevent hangLuca Barbieri
nouveau_gem_ioctl_cpu_prep calls ttm_bo_wait without the bo lock held. ttm_bo_wait unlocks that lock, and so must be called with it held.

2010-02-09drm/nouveau: Fixup semaphores on pre-nv50 cards.Francisco Jerez
Apparently, they generate a PFIFO interrupt each time one of the semaphore methods is executed if its ctxdma wasn't manually marked as valid. This patch makes it flip the valid bit in response to the DMA_SEMAPHORE method (which triggers the IRQ even for a valid ctxdma).

2010-02-08V4L/DVB: dvb-core: fix initialization of feeds list in demux filterFrancesco Lavra
A DVB demultiplexer device can be used to set up either a PES filter or a section filter. In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.

2010-02-07Fix race in tty_fasync() properlyLinus Torvalds
This reverts commit 703625118069 ("tty: fix race in tty_fasync") and commit b04da8bfdfbb ("fnctl: f_modown should call write_lock_irqsave/ restore") that tried to fix up some of the fallout but was incomplete. It turns out that we really cannot hold 'tty->ctrl_lock' over calling __f_setown, because not only did that cause problems with interrupt disables (which the second commit fixed), it also causes a potential ABBA deadlock due to lock ordering. Thanks to Tetsuo Handa for following up on the issue, and running lockdep to show the problem. It goes roughly like this: - f_getown gets filp->f_owner.lock for reading without interrupts disabled, so an interrupt that happens while that lock is held can cause a lockdep chain from f_owner.lock -> sighand->siglock. - at the same time, the tty->ctrl_lock -> f_owner.lock chain that commit 703625118069 introduced, together with the pre-existing sighand->siglock -> tty->ctrl_lock chain means that we have a lock dependency the other way too. So instead of extending tty->ctrl_lock over the whole __f_setown() call, we now just take a reference to the 'pid' structure while holding the lock, and then release it after having done the __f_setown. That still guarantees that 'struct pid' won't go away from under us, which is all we really ever needed.

2010-02-05hwmon: (w83781d) Request I/O ports individually for probingJean Delvare
Different motherboards have different PNP declarations for W83781D/W83782D chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

2010-02-05usb: r8a66597-hcd: Fix up spinlock recursion in root hub polling.Paul Mundt
The current root hub polling code exhibits a spinlock recursion on the private controller lock. r8a66597_root_hub_control() is called from r8a66597_timer() which grabs the lock and disables IRQs. The following chain emerges: r8a66597_timer() <-- lock taken r8a66597_root_hub_control() r8a66597_check_syssts() usb_hcd_poll_rh_status() <-- acquires the same lock /* insert death here */ The entire chain requires IRQs to be disabled, so we just unlock and relock around the call to usb_hcd_poll_rh_status() while leaving the IRQ state unchanged.

This implements the same D-cache flushing logic for r8a66597-hcd as Catalin's isp1760 (http://patchwork.kernel.org/patch/76391/) change, with the same note applying here as well: When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

2010-02-05drm/radeon/kms: don't call suspend path before cleaning up GPUJerome Glisse
In suspend path we unmap the GART table while in cleaning up path we will unbind buffer and thus try to write to unmapped GART leading to oops. In order to avoid this we don't call the suspend path in cleanup path. Cleanup path is clever enough to desactive GPU like the suspend path is doing, thus this was redondant.

2010-02-05drm/r100/kms: Emit cache flush to the end of command buffer. (v2)Pauli Nieminen
Cache flush is required in case CPU is accessing rendered data. This fixes glean/readPixSanity test case and random rendering errors in sauerbraten and warzone2100. v2 Fix comment ordering in r100_fence_ring_emit and remove extra defines added in first version.

2010-02-05drm/radeon/kms: fix regression rendering issue on R6XX/R7XXJerome Glisse
It seems that some R6XX/R7XX silently ignore HDP flush when programmed through ring, this patch addback an ioctl callback to allow R6XX/R7XX hw to perform such flush through MMIO in order to fix a regression.

2010-02-05drm/radeon/kms: move blit initialization after we disabled VGAJerome Glisse
VGA might be overwritting VRAM and corrupt our blit shader leading to corruption, it likely won't happen if you load fbcon right after radeon.

2010-02-04igb: make certain to reassign legacy interrupt vectors after resetAlexander Duyck
This change corrects an issue that will cause false hangs when using either 82575 or 82580 in legacy interrupt mode. The issue is caused when there is a slow traffic flow and an "ethtool -r" is executed while using legacy or MSI interrupts. MSI-X is not affected by this issue due to the fact that we were already reconfiguring the vectors after reset. If possible it would be best to push this for net-2.6 since it is resolving a bug but if that is not possible then net-next-2.6 will be fine.

acpi_lid_open() could take up to 10ms on my computer. Some component is calling the drm GETCONNECTOR ioctl many times in a row. This results in flickering (for example, when starting a video).
