This patch adds support for the GPIO/pinmux controller found on the VIA VT8500 and Wondermedia WM8xxx-series SoCs. Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850. Signed-off-by:

Several functions in of/base.c have the same code duplicated for finding and validating a property and value. struct property *prop = of_find_property(np, propname, NULL); if (!prop) return -EINVAL; if (!prop->value) return -ENODATA; if (<some length> > prop->length) return -EOVERFLOW; This patch adds of_find_property_value_of_size() which performs the equivalent of the above code and removes the instances where it was duplicated in several functions.

When KMS has parsed an EDID "detailed timing", it leaves the frame rate zeroed. Consecutive (debug-) output of that mode thus yields 0 for vsync. This simple fix also speeds up future invocations of drm_mode_vrefresh(). While it is debatable whether this qualifies as a -stable fix I'd apply it for consistency's sake; drm_helper_probe_single_connector_modes() does the same thing already for all probed modes.

EDID spreads some values across multiple bytes; bit-fiddling is needed to retrieve these. The current code to parse "detailed timings" has a cut&paste error that results in a vsync offset of at most 15 lines instead of 63. See http://en.wikipedia.org/wiki/EDID and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why that needs to be a left shift. Cc: stable@vger.kernel.org Signed-off-by:

mnt_drop_write() must be called only if mnt_want_write() succeeded, otherwise the mnt_writers counter will diverge. mnt_writers counters are used to check if remounting FS as read-only is OK, so after an extra mnt_drop_write() call, it would be impossible to remount mqueue FS as read-only. Besides, on umount a warning would be printed like this one: ===================================== [ BUG: bad unlock balance detected! ] 3.9.0-rc3 #5 Not tainted ------------------------------------- a.out/12486 is trying to release lock (sb_writers) at: mnt_drop_write+0x1f/0x30 but there are no more locks to release!

There were reports of the igb driver unmapping buffers without calling dma_mapping_error. On closer inspection issues were found in the DMA debug API and how it handled multiple mappings of the same buffer. The issue I found is the fact that the debug_dma_mapping_error would only set the map_err_type to MAP_ERR_CHECKED in the case that the was only one match for device and device address. However in the case of non-IOMMU, multiple addresses existed and as a result it was not setting this field once a second mapping was instantiated. I have resolved this by changing the search so that it instead will now set MAP_ERR_CHECKED on the first buffer that matches the device and DMA address that is currently in the state MAP_ERR_NOT_CHECKED. A secondary side effect of this patch is that in the case of multiple buffers using the same address only the last mapping will have a valid map_err_type. The previous mappings will all end up with map_err_type set to MAP_ERR_CHECKED because of the dma_mapping_error call in debug_dma_map_page. However this behavior may be preferable as it means you will likely only see one real error per multi-mapped buffer, versus the current behavior of multiple false errors mer multi-mapped buffer.

In check_unmap() it is possible to get into a dead-locked state if dma_mapping_error is called. The problem is that the bucket is locked in check_unmap, and locked again by debug_dma_mapping_error which is called by dma_mapping_error. To resolve that we must release the lock on the bucket before making the call to dma_mapping_error.

On some revisions of AT91 SoCs, the RTC IMR register is not working. Instead of elaborating a workaround for that specific SoC or IP version, we simply use a software variable to store the Interrupt Mask Register and modify it for each enabling/disabling of an interrupt. The overhead of this is negligible anyway. The interrupt mask register (IMR) for the RTC is broken on the AT91SAM9x5 sub-family of SoCs (good overview of the members here: http://www.eewiki.net/display/linuxonarm/AT91SAM9x5 ). The "user visible effect" is the RTC doesn't work. That sub-family is less than two years old and only has devicetree (DT) support and came online circa lk 3.7 . The dust is yet to settle on the DT stuff at least for AT91 SoCs (translation: lots of stuff is still broken, so much that it is hard to know where to start). The fix in the patch is pretty simple: just shadow the silicon IMR register with a variable in the driver. Some older SoCs (pre-DT) use the the rtc-at91rm9200 driver (e.g. obviously the AT91RM9200) and they should not be impacted by the change. There shouldn't be a large volume of interrupts associated with a RTC. Signed-off-by:

Booting with 32 TBytes memory hits BUG at mm/page_alloc.c:552! (output below). The key hint is "page 4294967296 outside zone". 4294967296 = 0x100000000 (bit 32 is set).

David said: Commit 6c0c0d4d ("poweroff: fix bug in orderly_poweroff()") apparently fixes one bug in orderly_poweroff(), but introduces another. The comments on orderly_poweroff() claim it can be called from any context - and indeed we call it from interrupt context in arch/powerpc/platforms/pseries/ras.c for example. But since that commit this is no longer safe, since call_usermodehelper_fns() is not safe in interrupt context without the UMH_NO_WAIT option. orderly_poweroff() can be used from any context but UMH_WAIT_EXEC is sleepable. Move the "force" logic into __orderly_poweroff() and change orderly_poweroff() to use the global poweroff_work which simply calls __orderly_poweroff(). While at it, remove the unneeded "int argc" and change argv_split() to use GFP_KERNEL. We use the global "bool poweroff_force" to pass the argument, this can obviously affect the previous request if it is pending/running. So we only allow the "false => true" transition assuming that the pending "true" should succeed anyway. If schedule_work() fails after that we know that work->func() was not called yet, it must see the new value. This means that orderly_poweroff() becomes async even if we do not run the command and always succeeds, schedule_work() can only fail if the work is already pending. We can export __orderly_poweroff() and change the non-atomic callers which want the old semantics. Signed-off-by:Oleg Nesterov <oleg@redhat.com> Reported-by:

hugetlb_total_pages is used for overcommit calculations but the current implementation considers only the default hugetlb page size (which is either the first defined hugepage size or the one specified by default_hugepagesz kernel boot parameter). If the system is configured for more than one hugepage size, which is possible since commit a137e1cc ("hugetlbfs: per mount huge page sizes") then the overcommit estimation done by __vm_enough_memory() (resp. shown by meminfo_proc_show) is not precise - there is an impression of more available/allowed memory. This can lead to an unexpected ENOMEM/EFAULT resp. SIGSEGV when memory is accounted. Testcase: boot: hugepagesz=1G hugepages=1 the default overcommit ratio is 50 before patch: egrep 'CommitLimit' /proc/meminfo CommitLimit: 55434168 kB after patch: egrep 'CommitLimit' /proc/meminfo CommitLimit: 54909880 kB [akpm@linux-foundation.org: coding-style tweak] Signed-off-by:

The AcpiMmioSel bit is bit 1 in the AcpiMmioEn register, but the current sp5100_tco driver is using bit 2.

Fortunately, no problems were caused by this typo, because the default value of the undocumented misused bit 2 seems to be zero. However, the sp5100_tco driver should use the correct bitmask value.

A problem was found on PC's with the SB700 chipset: The PC fails to load BIOS after running the 3.8.x kernel until the power is completely cut off. It occurs in all 3.8.x versions and the mainline version as of 2/4. The issue does not occur with the 3.7.x builds. There are two methods for accessing the watchdog registers. 1. Re-programming a resource address obtained by allocate_resource() to chipset. 2. Use the direct memory-mapped IO access. The method 1 can be used by all the chipsets (SP5100, SB7x0, SB8x0 or later). However, experience shows that only PC with the SB8x0 (or later) chipsets can use the method 2. This patch removes the method 1, because the critical problem was found. That's why the watchdog timer was able to be used on SP5100 and SB7x0 chipsets until now.

Dave Jones found another /proc issue with his Trinity tool: thanks to the namespace model, we can have multiple /proc dentries that point to the same inode, aliasing directories in /proc/<pid>/net/ for example. This ends up being a total disaster, because it acts like hardlinked directories, and causes locking problems. We rely on the topological sort of the inodes pointed to by dentries, and if we have aliased directories, that odering becomes unreliable. In short: don't do this. Multiple dentries with the same (directory) inode is just a bad idea, and the namespace code should never have exposed things this way. But we're kind of stuck with it. This solves things by just always allocating a new inode during /proc dentry lookup, instead of using "iget_locked()" to look up existing inodes by superblock and number. That actually simplies the code a bit, at the cost of potentially doing more inode [de]allocations. That said, the inode lookup wasn't free either (and did a lot of locking of inodes), so it is probably not that noticeable. We could easily keep the old lookup model for non-directory entries, but rather than try to be excessively clever this just implements the minimal and simplest workaround for the problem.

NVIDIA's Tegra SoC allows read/write of controller register only if controller clock is enabled. System hangs if read/write happens to registers without enabling clock. clk_prepare_enable() can be fail due to unknown reason and hence adding check for return value of this function. If this function success then only access register otherwise return to caller with error. Signed-off-by:
