2017-10-23platform/x86: intel_pmc_ipc: Use spin_lock to protect GCR updatesKuppuswamy Sathyanarayanan
Currently, update_no_reboot_bit() function implemented in this driver uses mutex_lock() to protect its register updates. But this function is called with in atomic context in iTCO_wdt_start() and iTCO_wdt_stop() functions in iTCO_wdt.c driver, which in turn causes "sleeping into atomic context" issue. This patch fixes this issue by replacing the mutex_lock() with spin_lock() to protect the GCR read/write/update APIs.

Workqueue used a mutex to arbitrate who gets to be the manager of a pool. When the manager role gets released, the mutex gets unlocked while holding the pool's irqsafe spinlock. This can lead to deadlocks as mutex's internal spinlock isn't irqsafe. This got discovered by recent fixes to mutex lockdep annotations. The fix is a bit invasive for rc6 but if anything were wrong with the fix it would likely have already blown up in -next, and we want the fix in -stable anyway" * 'for-4.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: replace pool->manager_arb mutex with a flag

2017-10-23nvme-rdma: fix possible hang when issuing commands during ctrl removalSagi Grimberg
nvme_rdma_queue_is_ready() fails requests in case a queue is not LIVE. If the controller is in RECONNECTING state, we might be in this state for a long time (until we successfully reconnect) and we are better off with failing the request fast. Otherwise, we fail with BLK_STS_RESOURCE to have the block layer try again soon. In case we are removing the controller when the admin queue is not LIVE, we will terminate the request with BLK_STS_RESOURCE but it happens before we call blk_mq_start_request() so the request timeout never expires, and the queue will never get back to LIVE (because we are removing the controller). This causes the removal operation to block infinitly [1]. Thus, if we are removing (state DELETING), and the queue is not LIVE, we need to fail the request permanently as there is no chance for it to ever complete successfully.
