Pull device tree conversions for arm-soc, part 1, from Olof Johansson: "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91.

Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform.

If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the user and ask them if the OUTPUT_MIN_CONFIG should be used as the starting point for make_min_config instead of MIN_CONFIG. This is usually the case, and to allow the user to do so, which is helpful if the user is creating different min configs based on tests, and they know one is a superset of another test, they can set USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting to use the OUTPUT_MIN_CONFIG and it will just use it. If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to use MIN_CONFIG instead. The default is that USE_OUTPUT_MIN_CONFIG is undefined.

If we reset the virtio-blk device before the requests already dispatched to the virtio-blk driver from the block layer are finised, we will stuck in blk_cleanup_queue() and the remove will fail. blk_cleanup_queue() calls blk_drain_queue() to drain all requests queued before DEAD marking. However it will never success if the device is already stopped. We'll have q->in_flight[] > 0, so the drain will not finish. How to reproduce the race: 1. hot-plug a virtio-blk device 2. keep reading/writing the device in guest 3. hot-unplug while the device is busy serving I/O Test: ~1000 rounds of hot-plug/hot-unplug test passed with this patch. Changes in v3: - Drop blk_abort_queue and blk_abort_request - Use __blk_end_request_all to complete request dispatched to driver Changes in v2: - Drop req_in_flight - Use virtqueue_detach_unused_buf to get request dispatched to driver Signed-off-by: NAsias He <asias@redhat.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

When a virtio_9p pci device is being removed, we should close down any active channels and free up resources, we're not supposed to BUG() if there's still an open channel since it's a valid case when removing the PCI device. Otherwise, removing the PCI device with an open channel would cause the following BUG(): [ 1184.671416] ------------[ cut here ]------------ [ 1184.672057] kernel BUG at net/9p/trans_virtio.c:618!

Posted to LKML: https://lkml.org/lkml/2012/4/23/322. 3) A couple of commits that improve the efficiency of the interaction between preemptible RCU and the scheduler, these two being all that survived an abortive attempt to allow preemptible RCU's __rcu_read_lock() to be inlined.

This reverts commit 8c01a529. It turns out the d_unhashed() check isn't unnecessary after all: while it's true that unhashing will increment the sequence numbers, that does not necessarily invalidate the RCU lookup, because it might have seen the dentry pointer (before it got unhashed), but by the time it loaded the sequence number, it could have seen the *new* sequence number (after it got unhashed). End result: we might look up an unhashed dentry that is about to be freed, with the sequence number never indicating anything bad about it. So checking that the dentry is still hashed (*after* reading the sequence number) is indeed the proper fix, and was never unnecessary.

This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk Only Transfers (BOT or BBB). BOT is the primary interface, UAS is the alternative interface. Note this series is dependent upon a single target core patch for adding se_cmd->unknown_data_length in target-pending/for-next, that got merged in the parent.
