2013-02-28md: expedite metadata update when switching read-auto -> activeNeilBrown
If something has failed while the array was read-auto, then when we switch to 'active' we need to update the metadata. This will happen anyway but it is good to expedite it, and also to ensure any failed device has been released by the underlying device before we try to action the ioctl which caused us to switch to 'active' mode.

2013-02-27ath9k_hw: improve reset reliability after errorsFelix Fietkau
On many different chips, important aspects of the MAC state are not fully cleared by a warm reset. This can show up as tx/rx hangs, those annoying "DMA failed to stop in 10 ms..." messages or other quirks. On AR933x, the chip can occasionally get stuck in a way that only a driver unload/reload or a reboot would bring it back to life. With this patch, a full reset is issued when bringing the chip out of FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down properly. This makes the DMA related error messages disappear completely in my tests on AR933x, and the chip does not get stuck anymore.

The ath9k commit 2ef167557c0a26c88162ecffb017bfcc51eb7b29 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.

2013-02-27usb/net/asix_devices: Add USBNET HG20F9 ethernet dongleGlen Turner
This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9.

2013-02-27sysrq: don't depend on weak undefined arrays to have an address that ↵Linus Torvalds
compares as NULL When taking an address of an extern array, gcc quite naturally should be able to say "an address of an object can never be NULL" and just optimize away the test entirely. However, the new alternate sysrq reset code (commit 154b7a489a5b: "Input: sysrq - allow specifying alternate reset sequence") did exactly that, and declared platform_sysrq_reset_seq[] as a weak array, and expecting that testing the address of the array would show whether it actually got linked against something or not. And that doesn't work with all gcc versions. Clearly it works with *some* versions of gcc, and maybe it's even supposed to work, but it really is a very fragile concept. So instead of testing the address of the weak variable, just create a weak instance of that array that is empty. If some platform then has a real platform_sysrq_reset_seq[] that overrides our weak one, the linker will switch to that one, and it all works without any run-time conditionals at all.

To fix it let's use platform_driver_probe() instead of platform_driver_register(), which disables binding/unbinding via sysfs.

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.

2013-02-27iwlwifi: mvm: Remove testing of static PIC in PhyDBDor Shaish
The PIC was supposed to be a small signature appended to the PhyDB data, but the signature isn't really static and thus attempting to check it just causes the warnings spuriously so remove them.

2013-02-27iwlwifi: fix wakeup status query and packet reportingJohannes Berg
The wakeup packet in the status response is padded out to a multiple of 4 bytes by the firmware for transfer to the host, take that into account when checking the length of the command. Also, the reported wakeup packet includes the FCS but the userspace API doesn't, so remove that. If it is a data packet it is reported as an 802.3 packet but I forgot to take into account and remove the encryption head/tail, fix all of that as well.

2013-02-26libceph: update osd request/reply encodingSage Weil
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.
