Pull MTD fixes from David Woodhouse: "The most important part of this is that it fixes a regression in Samsung NAND chip detection, introduced by some rework which went into 3.7. The initial fix wasn't quite complete, so it's in two parts. In fact the first part is committed twice (Artem committed his own copy of the same patch) and I've merged Artem's tree into mine which already had that fix. I'd have recommitted that to make it somewhat cleaner, but figured by this point in the release cycle it was better to merge *exactly* the commits which have been in linux-next. If I'd recommitted, I'd also omit the sparse warning fix. But it's there, and it's harmless — just marking one function as 'static' in onenand code. This also includes a couple more fixes for stable: an AB-BA deadlock in JFFS2, and an invalid range check in slram." * tag 'for-linus-20121123' of git://git.infradead.org/mtd-2.6: mtd: nand: fix Samsung SLC detection regression mtd: nand: fix Samsung SLC NAND identification regression jffs2: Fix lock acquisition order bug in jffs2_write_begin mtd: onenand: Make flexonenand_set_boundary static mtd: slram: invalid checking of absolute end address mtd: ofpart: Fix incorrect NULL check in parse_ofoldpart_partitions() mtd: nand: fix Samsung SLC NAND identification regression

2012-11-23PM / QoS: fix wrong error-checking conditionGuennadi Liakhovetski
dev_pm_qos_add_request() can return 0, 1, or a negative error code, therefore the correct error test is "if (error < 0)." Checking just for non-zero return code leads to erroneous setting of the req->dev pointer to NULL, which then leads to a repeated call to dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn leads to an Oops, when the I2C host adapter is unloaded and reloaded again because of the inconsistent state of its QoS request list.

Request based dm attempts to re-run the request queue off the request completion path.

2012-11-22md/raid10: decrement correct pending counter when writing to replacement.NeilBrown
When a write to a replacement device completes, we carefully and correctly found the rdev that the write actually went to and the blithely called rdev_dec_pending on the primary rdev, even if this write was to the replacement. This means that any writes to an array while a replacement was ongoing would cause the nr_pending count for the primary device to go negative, so it could never be removed. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid10: close race that lose writes lost when replacement completes.NeilBrown
When a replacement operation completes there is a small window when the original device is marked 'faulty' and the replacement still looks like a replacement. The faulty should be removed and the replacement moved in place very quickly, bit it isn't instant. So the code write out to the array must handle the possibility that the only working device for some slot in the replacement - but it doesn't. If the primary device is faulty it just gives up. This can lead to corruption. So make the code more robust: if either the primary or the replacement is present and working, write to them. Only when neither are present do we give up. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid5: Make sure we clear R5_Discard when discard is finished.NeilBrown
commit 9e44476851e91c86c98eb92b9bc27fb801f89072 MD: raid5 avoid unnecessary zero page for trim change raid5 to clear R5_Discard when the complete request is handled rather than when submitting the per-device discard request. However it did not clear R5_Discard for the parity device. This means that if the stripe_head was reused before it expired from the cache, the setting would be wrong and a hang would result. Also if the R5_Uptodate bit happens to be set, R5_Discard again won't be cleared. But R5_Uptodate really should be clear at this point. So make sure R5_Discard is cleared in all cases, and clear R5_Uptodate when a 'discard' completes. Signed-off-by: NeilBrown <neilb@suse.de>
2012-11-22md/raid5: move resolving of reconstruct_state earlier inNeilBrown
stripe_handle. The chunk of code in stripe_handle which responds to a *_result value in reconstruct_state is really the completion of some processing that happened outside of handle_stripe (possibly asynchronously) and so should be one of the first things done in handle_stripe(). After the next patch it will be important that it happens before handle_stripe_clean_event(), as that will clear some dev->flags bit that this code tests. Signed-off-by: NeilBrown <neilb@suse.de>

2012-11-21team: bcast: convert return value of team_dev_queue_xmit() to bool correctlyJiri Pirko
The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*. bc_trasmit() should return true in case all went well. So use ! to get correct retval from team_dev_queue_xmit() result. This bug caused iface statistics to be badly computed.

2012-11-21xen/netfront: handle compound page fragments on transmitIan Campbell
An SKB paged fragment can consist of a compound page with order > 0. However the netchannel protocol deals only in PAGE_SIZE frames. Handle this in xennet_make_frags by iterating over the frames which make up the page. This is the netfront equivalent to 6a8ed462f16b for netback.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into for-davem John W. Linville says: ==================== This is a batch of fixes intended for 3.7... Included are two pulls. Regarding the mac80211 tree, Johannes says: "Please pull my mac80211.git tree (see below) to get two more fixes for 3.7. Both fix regressions introduced *before* this cycle that weren't noticed until now, one for IBSS not cleaning up properly and the other to add back the "wireless" sysfs directory for Fedora's startup scripts." Regarding the iwlwifi tree, Johannes says: "Please also pull my iwlwifi.git tree, I have two fixes: one to remove a spurious warning that can actually trigger in legitimate situations, and the other to fix a regression from when monitor mode was changed to use the "sniffer" firmware mode." Also included is an nfc tree pull. Samuel says: "We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix. Moreover, we also have an LLCP adapter linked list insertion fix." On top of that, a few more bits... Albert Pool adds a USB ID to rtlwifi. Bing Zhao provides two mwifiex fixes -- one to fix a system hang during a command timeout, and the other to properly report a suspend error to the MMC core. Finally, Sujith Manoharan fixes a thinko that would trigger an ath9k hang during device reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2012-11-20xen/privcmd: Correctly return success from IOCTL_PRIVCMD_MMAPBATCHMats Petersson
This is a regression introduced by ceb90fa0 (xen/privcmd: add PRIVCMD_MMAPBATCH_V2 ioctl). It broke xentrace as it used xc_map_foreign() instead of xc_map_foreign_bulk(). Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious that it broke. The return value is set early on to -EINVAL, and if all goes well, the "set top bits of the MFN's" never gets called, so the return value is still EINVAL when the function gets to the end, causing the caller to think it went wrong (which it didn't!) Now also including Andres "move the ret = -EINVAL into the error handling path, as this avoids other similar errors in future.
