+Subject: aio: fix uncorrent dirty pages accouting when truncating AIO ring buffer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Gu Zheng <guz.fnst@cn.fujitsu.com>
+
+commit 835f252c6debd204fcd607c79975089b1ecd3472 upstream.
+
+https://bugzilla.kernel.org/show_bug.cgi?id=86831
+
+Markus reported that when shutting down mysqld (with AIO support,
+on a ext3 formatted Harddrive) leads to a negative number of dirty pages
+(underrun to the counter). The negative number results in a drastic reduction
+of the write performance because the page cache is not used, because the kernel
+thinks it is still 2 ^ 32 dirty pages open.
+
+Add a warn trace in __dec_zone_state will catch this easily:
+
+static inline void __dec_zone_state(struct zone *zone, enum
+ zone_stat_item item)
+{
+ atomic_long_dec(&zone->vm_stat[item]);
++ WARN_ON_ONCE(item == NR_FILE_DIRTY &&
+ atomic_long_read(&zone->vm_stat[item]) < 0);
+ atomic_long_dec(&vm_stat[item]);
+}

+
+The cause is that we set the aio ring file pages as *DIRTY* via SetPageDirty
+(bypasses the VFS dirty pages increment) when init, and aio fs uses
+*default_backing_dev_info* as the backing dev, which does not disable
+the dirty pages accounting capability.
+So truncating aio ring file will contribute to accounting dirty pages (VFS
+dirty pages decrement), then error occurs.
+
+The original goal is keeping these pages in memory (can not be reclaimed
+or swapped) in life-time via marking it dirty. But thinking more, we have
+already pinned pages via elevating the page's refcount, which can already
+achieve the goal, so the SetPageDirty seems unnecessary.
+
+In order to fix the issue, using the __set_page_dirty_no_writeback instead
+of the nop .set_page_dirty, and dropped the SetPageDirty (don't manually
+set the dirty flags, don't disable set_page_dirty(), rely on default behaviour).
+
+With the above change, the dirty pages accounting can work well. But as we
+known, aio fs is an anonymous one, which should never cause any real write-back,
+we can ignore the dirty pages (write back) accounting by disabling the dirty
+pages (write back) accounting capability. So we introduce an aio private
+backing dev info (disabled the ACCT_DIRTY/WRITEBACK/ACCT_WB capabilities) to
+replace the default one.

+Subject: ALSA: usb-audio: Add ctrl message delay quirk for
+ Marantz/Denon devices
+
+From: Jurgen Kramer <gtmkramer@xs4all.nl>
+
+commit 6e84a8d7ac3ba246ef44e313e92bc16a1da1b04a upstream.
+
+This patch adds a USB control message delay quirk for a few specific Marantz/Denon
+devices. Without the delay the DACs will not work properly and produces the
+following type of messages:
+
+Nov 15 10:09:21 orwell kernel: [ 91.342880] usb 3-13: clock source 41 is not valid, cannot use
+Nov 15 10:09:21 orwell kernel: [ 91.343775] usb 3-13: clock source 41 is not valid, cannot use
+
+There are likely other Marantz/Denon devices using the same USB module which exhibit the
+same problems. But as this cannot be verified I limited the patch to the devices
+I could test.
+
+The following two devices are covered by this path:
+- Marantz SA-14S1
+- Marantz HD-DAC1

+Subject: USB: xhci: don't start a halted endpoint before its new dequeue is set
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit c3492dbfa1050debf23a5b5cd2bc7514c5b37896 upstream.
+
+A halted endpoint ring must first be reset, then move the ring
+dequeue pointer past the problematic TRB. If we start the ring too
+early after reset, but before moving the dequeue pointer we
+will end up executing the same problematic TRB again.
+
+As we always issue a set transfer dequeue command after a reset
+endpoint command we can skip starting endpoint rings at reset endpoint
+command completion.
+
+Without this fix we end up trying to handle the same faulty TD for
+contol endpoints. causing timeout, and failing testusb ctrl_out write
+tests.

+Subject: usb: xhci: rework root port wake bits if controller isn't allowed to wakeup
+
+From: Lu Baolu <baolu.lu@linux.intel.com>
+
+commit a1377e5397ab321e21b793ec8cd2b6f12bd3c718 upstream.
+
+When system is being suspended, if host device is not allowed to do wakeup,
+xhci_suspend() needs to clear all root port wake on bits. Otherwise, some
+platforms may generate spurious wakeup, even if PCI PME# is disabled.
+
+The initial commit ff8cbf250b44 ("xhci: clear root port wake on bits"),
+which also got into stable, turned out to not work correctly and had to
+be reverted, and is now rewritten.
