2011-12-20mfd: Set da903x bits if new value is different from the old oneAxel Lin1-1/+1
It does not make sense to write new value only when all the bit_mask bits are zero. We need to write new value if the bit mask fields of new value is not equal to old value. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1. It blows up the i915 seqno tracking, resulting in the BUG_ON(seqno == 0); in i915_wait_request() triggering, which will cause lock-ups.

2011-12-16drm/i915: enable semaphores on per-device defaultsEugeni Dodonov3-4/+21
This adds a default setting for semaphores parameter, and enables semaphores by default on IVB. For now, as semaphores interaction with VTd causes random issues on SNB, we do not enable them by default. But they can still be enabled via the semaphores=1 kernel parameter. v2: enables semaphores on SNB when IO remapping is disabled, with base on Keith Packard patch.

2011-12-16drm/i915: prevent division by zero when asking for chipset powerEugeni Dodonov2-0/+11
This prevents an in-kernel division by zero which happens when we are asking for i915_chipset_val too quickly, or within a race condition between the power monitoring thread and userspace accesses via debugfs. The issue can be reproduced easily via the following command: while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; done This is particularly dangerous because it can be triggered by a non-privileged user by just reading the debugfs entry.

2011-12-15xen/swiotlb: Use page alignment for early buffer allocation.Konrad Rzeszutek Wilk1-2/+2
This fixes an odd bug found on a Dell PowerEdge 1850/0RC130 (BIOS A05 01/09/2006) where all of the modules doing pci_set_dma_mask would fail with: ata_piix 0000:00:1f.1: enabling device (0005 -> 0007) ata_piix 0000:00:1f.1: can't derive routing for PCI INT A ata_piix 0000:00:1f.1: BMDMA: failed to set dma mask, falling back to PIO The issue was the Xen-SWIOTLB was allocated such as that the end of buffer was stradling a page (and also above 4GB). The fix was spotted by Kalev Leonid which was to piggyback on git commit e79f86b2ef9c0a8c47225217c1018b7d3d90101c "swiotlb: Use page alignment for early buffer allocation" which: We could call free_bootmem_late() if swiotlb is not used, and it will shrink to page alignment. So alloc them with page alignment at first, to avoid lose two pages And doing that fixes the outstanding issue.

2011-12-13ibft: Fix finding IBFT ACPI table on UEFIYinghai Lu2-26/+42
Found one system with UEFI/iBFT, kernel does not detect the iBFT during iscsi_ibft module loading. Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier - specifically in setup_arch() before ACPI is enabled. Try to split acpi checking code out and call that later At that time ACPI iBFT already get permanent mapped with ioremap. So isa_virt_to_bus() will get wrong phys from right virt address. We could just skip that phys address printing. For legacy one, print the found address early. -v2: update comments and description according to Konrad. -v3: fix problem about module use case that is found by Konrad. -v4: use acpi_get_table() instead of acpi_table_parse() to handle module use case that is found by Konrad again..

2011-12-12block/swim3: Locking fixesBenjamin Herrenschmidt1-147/+215
The old PowerMac swim3 driver has some "interesting" locking issues, using a private lock and failing to lock the queue before completing requests, which triggered WARN_ONs among others. This rips out the private lock, makes everything operate under the block queue lock, and generally makes things simpler. We used to also share a queue between the two possible instances which was problematic since we might pick the wrong controller in some cases, so make the queue and the current request per-instance and use queuedata to point to our private data which is a lot cleaner. We still share the queue lock but then, it's nearly impossible to actually use 2 swim3's simultaneously: one would need to have a Wallstreet PowerBook, the only machine afaik with two of these on the motherboard, and populate both hotswap bays with a floppy drive (the machine ships only with one), so nobody cares... While at it, add a little fix to clear up stale interrupts when loading the driver or plugging a floppy drive in a bay.

2011-12-11mmc: core: Fix deadlock when the CONFIG_MMC_UNSAFE_RESUME is not definedSujit Reddy Thumma1-1/+2
mmc_suspend_host() tries to claim host during suspend and release it only when the bus suspend operation is compeleted. If CONFIG_MMC_UNSAFE_RESUME is defined and the host is flagged as removable, mmc_suspend_host() tries to remove the card. In this process, the file system sync can get blocked trying to acquire host which is already claimed by mmc_suspend_host() causing deadlock. Fix this deadlock by releasing host before ->remove() is called.

2011-12-11mmc: sdhci-s3c: Remove old and misprototyped suspend operationsMark Brown1-2/+0
Now that the driver is using dev_pm_ops the suspend operations in the platform_driver structure won't get called so don't need to be there, and certainly shouldn't be the same function as dev_pm_ops since the signatures are different.
