2013-02-27dma-buf: implement vmap refcounting in the interface logicDaniel Vetter
All drivers which implement this need to have some sort of refcount to allow concurrent vmap usage. Hence implement this in the dma-buf core. To protect against concurrent calls we need a lock, which potentially causes new funny locking inversions. But this shouldn't be a problem for exporters with statically allocated backing storage, and more dynamic drivers have decent issues already anyway. Inspired by some refactoring patches from Aaron Plattner, who implemented the same idea, but only for drm/prime drivers. v2: Check in dma_buf_release that no dangling vmaps are left. Suggested by Aaron Plattner. We might want to do similar checks for attachments, but that's for another patch. Also fix up ERR_PTR return for vmap. v3: Check whether the passed-in vmap address matches with the cached one for vunmap. Eventually we might want to remove that parameter - compared to the kmap functions there's no need for the vaddr for unmapping. Suggested by Chris Wilson. v4: Fix a brown-paper-bag bug spotted by Aaron Plattner.

2013-02-26libceph: add support for HASHPSPOOL pool flagSage Weil
The legacy behavior adds the pgid seed and pool together as the input for CRUSH. That is problematic because each pool's PGs end up mapping to the same OSDs: 1.5 == 2.4 == 3.3 == ... Instead, if the HASHPSPOOL flag is set, we has the ps and pool together and feed that into CRUSH. This ensures that two adjacent pools will map to an independent pseudorandom set of OSDs. Advertise our support for this via a protocol feature flag. Signed-off-by: Sage Weil <sage@inktank.com> Reviewed-by: Alex Elder <elder@inktank.com>

Use the new version of the encoding for osd requests and replies. In the process, update the way we are tracking request ops and reply lengths and results in the struct ceph_osd_request. Update the rbd and fs/ceph users appropriately. The main changes are: - we keep pointers into the request memory for fields we need to update each time the request is sent out over the wire - we keep information about the result in an array in the request struct where the users can easily get at it.

2013-02-26rbd: pass length, not op for osd completionsAlex Elder
The only thing type-specific osd completion functions do with their osd op parameter is (in some cases) extract the number of bytes transferred from it. In the other cases, the xferred bytes field is not used, and total message data transfer byte count (which may well be zero) is used. Just set the object request transfer count in the main osd request callback function and provide that to the other routines. There is then no longer any need to pass the op pointer to the type-specific completion routines, so drop those parameters. Stop doing anything with the total message data length.

2013-02-26stop_machine: Mark per cpu stopper enabled earlyThomas Gleixner
commit 14e568e78 (stop_machine: Use smpboot threads) introduced the following regression: Before this commit the stopper enabled bit was set in the online notifier. CPU0 CPU1 cpu_up cpu online hotplug_notifier(ONLINE) stopper(CPU1)->enabled = true; ... stop_machine() The conversion to smpboot threads moved the enablement to the wakeup path of the parked thread. The majority of users seem to have the following working order: CPU0 CPU1 cpu_up cpu online unpark_threads() wakeup(stopper[CPU1]) .... stopper thread runs stopper(CPU1)->enabled = true; stop_machine() But Konrad and Sander have observed: CPU0 CPU1 cpu_up cpu online unpark_threads() wakeup(stopper[CPU1]) .... stop_machine() stopper thread runs stopper(CPU1)->enabled = true; Now the stop machinery kicks CPU0 into the stop loop, where it gets stuck forever because the queue code saw stopper(CPU1)->enabled == false, so CPU0 waits for CPU1 to enter stomp_machine, but the CPU1 stopper work got discarded due to enabled == false. Add a pre_unpark function to the smpboot thread descriptor and call it before waking the thread. This fixes the problem at hand, but the stop_machine code should be more robust. The stopper->enabled flag smells fishy at best. Thanks to Konrad for going through a loop of debug patches and providing the information to decode this issue.

2013-02-26USB: EHCI: revert "remove ASS/PSS polling timeout"Alan Stern
This patch (as1649) reverts commit 55bcdce8a8228223ec4d17d8ded8134ed265d2c5 (USB: EHCI: remove ASS/PSS polling timeout). That commit was written under the assumption that some controllers may take a very long time to turn off their async and periodic schedules. It now appears that in fact the schedules do get turned off reasonably quickly, but some controllers occasionally leave the schedules' status bits turned on and consequently ehci-hcd can't tell that the schedules are off. VIA controllers in particular have this problem. ehci-hcd tells the hardware to turn off the async schedule, the schedule does get turned off, but the status bit remains on. Since the EHCI spec requires that the schedules not be re-enabled until the previous disable has taken effect, with an unlimited timeout the async schedule never gets turned back on. The resulting symptom is that the system is unable to communicate with USB devices.

2013-02-26iwlwifi: mvm: fix AP/GO mode station removalJohannes Berg
When stations are removed while packets are in the queue, we drain the queues first, and then remove the stations. If this happens in AP mode while the interface is removed the MAC context might be removed from the firmware before we removed the station(s), resulting in a SYSASSERT 3421. This is because we remove the MAC context from the FW in stop_ap(), but only flush the station drain work later in remove_interface(). Refactor the code a bit to have a common MAC context removal preparation first to solve this.

2013-02-26iwlwifi: always copy first 16 bytes of commandsJohannes Berg
The FH hardware will always write back to the scratch field in commands, even host commands not just TX commands, which can overwrite parts of the command. This is problematic if the command is re-used (with IWL_HCMD_DFL_NOCOPY) and can cause calibration issues. Address this problem by always putting at least the first 16 bytes into the buffer we also use for the command header and therefore make the DMA engine write back into this. For commands that are smaller than 16 bytes also always map enough memory for the DMA engine to write back to.
