Some kirkwood boards don't use both pins as they are not connected, and don't set the corresponding value in platform_data. This will leave the unset values in platform_data initialized as 0, which is in fact a valid gpio pin. mvsdio will grab that pin and configure it as gpio, which in turn breaks nand controller as mpp0 also carries nand_io2. This patch fixes the above by initializing unused gpio functions in the platform_data with an invalid (-1) value.

| 7f23f62 | Gregory CLEMENT | 20 March 2013, 15:09:35 UTC | arm: mvebu: Use local interrupt only for the timer 0 The commit 3a6f08a37 "arm: mvebu: Add support for local interrupt", managed the 28th first interrupts as local interrupt to match the hardware specification. Among these interrupts there are the Gigabits Ethernet ones used by the mvneta driver. Unfortunately the state of the percpu_irq API prevents the driver to use it. Indeed the interrupts have to be freed when the .stop() function is called. As the free_percpu_irq() function don't disable the interrupt line, we have to do it on each CPU before calling this. The function disable_percpu_irq() only disable the percpu on the current CPU and there is no function which allows to disable a percpu irq on a given CPU. Waiting for the extension of the percpu_irq API, this fix allows to use again the mvneta driver.

On some u8500 based boards, the FMSC clock which is usually used for flash, is wired up to the SMSC911x Ethernet driver. However, the SMSC911x doesn't have common clk support yet, rendering it unusable. Prior to the introduction of common clk the FMSC clock was default on; however, common clk disables all clocks by default and insists drivers take responsibility to enable theirs. This fix enables the FMSC clock on Snowball, subsequently turning on the SMSC911x Ethernet chip. It will be removed when the driver is compatible with common clk.

The dependency comes from the fact that the timer init code starts to use clocks and hwmod and we need clocks to be initialized by then. There are various problems doing clk inits this early, one is, not being able to do dynamic clk registrations and hence the dependency on clk-private.h. The other is, inability to debug early kernel crashes without enabling DEBUG_LL and earlyprintk. Doing early clk init also exposed another instance of a kernel panic due to a BUG() when CONFIG_DEBUG_SLAB is enabled.

It was a know issue, that slab allocations would fail when common clock core tries to cache parent pointers for mux clocks on OMAP, and hence a patch 'clk: Allow late cache allocation for clk->parents, commit 7975059d' was added to work this problem around. A BUG() within kmalloc() with CONFIG_DEBUG_SLAB enabled was completely overlooked causing this regression. More details on the issue reported can be found here, http://www.mail-archive.com/linux-omap@vger.kernel.org/msg85932.html With all these issues around clk inits happening way too early, it makes sense to at least move them to a point where dynamic memory allocations are possible. So move them to a point just before the timer code starts using clocks and hwmod. This should at least pave way for clk inits on OMAP moving to dynamic clock registrations instead of using the static macros defined in clk-private.h. The issue with kernel panic while CONFIG_DEBUG_SLAB is enabled was reported by Piotr Haber and Tony Lindgren and this patch fixes the reported issue as well.

| 96e7d7a | Alexander Duyck | 22 March 2013, 22:04:49 UTC | dma-debug: update DMA debug API to better handle multiple mappings of a buffer 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.

| 0ef1594 | Nicolas Ferre | 22 March 2013, 22:04:47 UTC | drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMR 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.

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.

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.

| 51f0885 | Linus Torvalds | 22 March 2013, 18:44:04 UTC | vfs,proc: guarantee unique inodes in /proc 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.

This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. When switching to tty ports, some lifetime assumptions were changed. Specifically, close can now be called before the final tty reference is dropped as part of hangup at device disconnect. Even with the ftdi private-data refcounting this means that the port private data can be freed while a process is sleeping on modem-status changes and thus cannot be relied on to detect disconnects when woken up.

| f853c61 | Jeff Layton | 11 March 2013, 13:52:19 UTC | cifs: ignore everything in SPNEGO blob after mechTypes We've had several reports of people attempting to mount Windows 8 shares and getting failures with a return code of -EINVAL. The default sec= mode changed recently to sec=ntlmssp. With that, we expect and parse a SPNEGO blob from the server in the NEGOTIATE reply. The current decode_negTokenInit function first parses all of the mechTypes and then tries to parse the rest of the negTokenInit reply. The parser however currently expects a mechListMIC or nothing to follow the mechTypes, but Windows 8 puts a mechToken field there instead to carry some info for the new NegoEx stuff. In practice, we don't do anything with the fields after the mechTypes anyway so I don't see any real benefit in continuing to parse them. This patch just has the kernel ignore the fields after the mechTypes. We'll probably need to reinstate some of this if we ever want to support NegoEx.

| 55a63d4 | Takashi Iwai | 21 March 2013, 16:20:12 UTC | ALSA: hda - Fix DAC assignment for independent HP The generic parser should evaluate the availability of the independent HP when specified. Otherwise a DAC without the direct connection to the corresponding pin may be assigned for the HP, but the driver doesn't check it at all. The problem was actually seen on some machines with VT1708s or equivalent codec, where DAC0 is assigned to HP although it can be connected only via aamix. This patch adds the badness evaluation for the independent HP to make it working properly.

Once the bootloader would load the selected kernel, the screen would go black. At first it was assumed that the mgag200 kms driver was hanging. But after setting up the grub serial output, it was seen that the driver was being loaded properly. After trying serval monitors, one finaly displayed the message "Frequency Out of Range". By comparing the kms pll algorithm with the previous mgag200 xorg driver pll algorithm, discrepencies were found. Once the kms pll algorithm was modified, the expected pll values were produced.

| d714aaf | Alan Stern | 20 March 2013, 19:07:26 UTC | USB: EHCI: fix regression in QH unlinking This patch (as1670) fixes a regression caused by commit 6402c796d3b4205d3d7296157956c5100a05d7d6 (USB: EHCI: work around silicon bug in Intel's EHCI controllers). The workaround goes through two IAA cycles for each QH being unlinked. During the first cycle, the QH is not added to the async_iaa list (because it isn't fully gone from the hardware yet), which means that list will be empty. Unfortunately, I forgot to update the IAA watchdog timer routine. It thinks that an empty async_iaa list means the timer expiration was an error, which isn't true any more. This problem didn't show up during initial testing because the controllers being tested all had working IAA interrupts. But not all controllers do, and when the watchdog timer expires, the empty-list check prevents the second IAA cycle from starting. As a result, URB unlinks never complete. The check needs to be removed. Among the symptoms of the regression are processes stuck in D wait states and hangs during system shutdown.

| eb49faa | Takashi Iwai | 15 March 2013, 08:19:11 UTC | ALSA: hda - Fix abuse of snd_hda_lock_devices() for DSP loader The current DSP loader code abuses snd_hda_lock_devices() for ensuring the DSP loader not conflicting with the other normal operations. But this trick obviously doesn't work for the PM resume since the streams are kept opened there where snd_hda_lock_devices() returns -EBUSY. That means we need another lock mechanism instead of abuse. This patch provides the new lock state to azx_dev. Theoretically it's possible that the DSP loader conflicts with the stream that has been already assigned for another PCM. If it's running, the DSP loader should simply fail. If not -- it's the case for PM resume --, we should assign this stream temporarily to the DSP loader, and take it back to the PCM after finishing DSP loading. If the PCM is operated during the DSP loading, it should get an error, too.

| e2e74d6 | Joe Thornber | 20 March 2013, 17:21:27 UTC | dm cache: fix race in writethrough implementation We have found a race in the optimisation used in the dm cache writethrough implementation. Currently, dm core sends the cache target two bios, one for the origin device and one for the cache device and these are processed in parallel. This patch avoids the race by changing the code back to a simpler (slower) implementation which processes the two writes in series, one after the other, until we can develop a complete fix for the problem. When the cache is in writethrough mode it needs to send WRITE bios to both the origin and cache devices. Previously we've been implementing this by having dm core query the cache target on every write to find out how many copies of the bio it wants. The cache will ask for two bios if the block is in the cache, and one otherwise. Then main problem with this is it's racey. At the time this check is made the bio hasn't yet been submitted and so isn't being taken into account when quiescing a block for migration (promotion or demotion). This means a single bio may be submitted when two were needed because the block has since been promoted to the cache (catastrophic), or two bios where only one is needed (harmless). I really don't want to start entering bios into the quiescing system (deferred_set) in the get_num_write_bios callback. Instead this patch simplifies things; only one bio is submitted by the core, this is first written to the origin and then the cache device in series. Obviously this will have a latency impact. deferred_writethrough_bios is introduced to record bios that must be later issued to the cache device from the worker thread. This deferred submission, after the origin bio completes, is required given that we're in interrupt context (writethrough_endio).
