+
+From: Rajkumar Kasirajan <rajkumar.kasirajan@stericsson.com>
+
+commit c0a5f4a05af588a0f9951f8d24e2564b09501918 upstream.
+
+The reset date of the ST Micro version of PL031 is 2000-01-01. The
+correct weekday for 2000-01-01 is saturday, but pl031 is initialized to
+sunday. This may lead to alarm malfunction, so configure the correct
+wday if RTC_DR indicates reset.

+
+From: Shaohua Li <shli@kernel.org>
+
+commit b5e1b8cee7ad58a15d2fa79bcd7946acb592602d upstream.
+
+A flush request is usually issued in transaction commit code path, so
+using GFP_KERNEL to allocate memory for flush request bio falls into
+the classic deadlock issue.
+
+This is suitable for any -stable kernel to which it applies as it
+avoids a possible deadlock.

+
+This implied a reference counting bug and the problem happened during
+mbind().
+
+mbind() applies a new memory policy to a range and uses mbind_range() to
+merge existing VMAs or split them as necessary. In the event of splits,
+mpol_dup() will allocate a new struct mempolicy and maintain existing
+reference counts whose rules are documented in
+Documentation/vm/numa_memory_policy.txt .
+
+The problem occurs with shared memory policies. The vm_op->set_policy
+increments the reference count if necessary and split_vma() and
+vma_merge() have already handled the existing reference counts.
+However, policy_vma() screws it up by replacing an existing
+vma->vm_policy with one that potentially has the wrong reference count
+leading to a premature free. This patch removes the damage caused by
+policy_vma().
+
+With this patch applied Dave's trinity tool runs an mbind test for 5
+minutes without error. /proc/slabinfo reported that there are no
+numa_policy or shared_policy_node objects allocated after the test
+completed and the shared memory region was deleted.

+Subject: SCSI: hpsa: Fix problem with MSA2xxx devices
+
+From: "Stephen M. Cameron" <scameron@beardog.cce.hp.com>
+
+commit 9bc3711cbb67ac620bf09b4a147cbab45b2c36c0 upstream.
+
+Upgraded firmware on Smart Array P7xx (and some others) made them show up as
+SCSI revision 5 devices and this caused the driver to fail to map MSA2xxx
+logical drives to the correct bus/target/lun. A symptom of this would be that
+the target ID of the logical drives as presented by the external storage array
+is ignored, and all such logical drives are assigned to target zero,
+differentiated only by LUN. Some multipath software reportedly does not deal
+well with this behavior, failing to recognize different paths to the same
+device as such.

+Subject: usb: usbtest: two super speed fixes for usbtest
+
+From: Paul Zimmerman <Paul.Zimmerman@synopsys.com>
+
+commit 6a23ccd216b6a8ba2c67a9f9d8969b4431ad2920 upstream.
+
+bMaxPacketSize0 field for super speed is a power of 2, not a count.
+The size itself is always 512.
+
+Max packet size for a super speed bulk endpoint is 1024, so
+allocate the urb size in halt_simple() accordingly.

+Subject: workqueue: skip nr_running sanity check in worker_enter_idle() if trustee is active
+
+From: Tejun Heo <tj@kernel.org>
+
+commit 544ecf310f0e7f51fa057ac2a295fc1b3b35a9d3 upstream.
+
+worker_enter_idle() has WARN_ON_ONCE() which triggers if nr_running
+isn't zero when every worker is idle. This can trigger spuriously
+while a cpu is going down due to the way trustee sets %WORKER_ROGUE
+and zaps nr_running.
+
+It first sets %WORKER_ROGUE on all workers without updating
+nr_running, releases gcwq->lock, schedules, regrabs gcwq->lock and
+then zaps nr_running. If the last running worker enters idle
+inbetween, it would see stale nr_running which hasn't been zapped yet
+and trigger the WARN_ON_ONCE().
+
+Fix it by performing the sanity check iff the trustee is idle.
