Salil d36d36ceac net: hns3: Fixes the missing u64_stats_fetch_begin_irq in 64-bit stats fetch
This patch fixes the missing u64_stats_fetch_begin_irq() while trying to
atomically do 64-bit RX/TX fetch. We did not get any error during test
as our SoC is 64-bit so all of these seq/lock operations results in NOOP.

As such, this seq lock supports has been added for the sake of completion
if this code ever runs on 32-bit platform and we are trying to do 64-bit
stats fetch.

Julian Wiedmann 0d6f02d375 s390/qeth: use skb_cow_head() for L2 OSA xmit
Taking a full copy via skb_realloc_headroom() on every xmit is overkill
and wastes CPU time; all we actually need is to push on the qeth_hdr.
So rework the L2 OSA TX path to avoid the copy.
Minor complications arise because struct qeth_hdr must not cross a page
boundary. So add a new helper qeth_push_hdr() that catches this, and
falls back to the hdr cache that we already use for IQDs.

This change uncovered that qeth's TX completion takes rather long.
Now that we no longer free the original skb straight away and thus call
skb->destructor later than before, throughput regresses significantly.
For now, restore old behaviour by adding an explicit skb_orphan(),
and a big TODO to improve the TX completion time.

For IQD we already need to fix up the qeth_hdr's length field, and
future changes will require more flexibility for OSA as well. The
device-specific path knows best what header length it requires, so just
pass it from there.

Thomas Gleixner 7edaeb6841 kernel/watchdog: Prevent false positives with turbo modes
The hardlockup detector on x86 uses a performance counter based on unhalted
CPU cycles and a periodic hrtimer. The hrtimer period is about 2/5 of the
performance counter period, so the hrtimer should fire 2-3 times before the
performance counter NMI fires. The NMI code checks whether the hrtimer
fired since the last invocation. If not, it assumess a hard lockup.

The calculation of those periods is based on the nominal CPU
frequency. Turbo modes increase the CPU clock frequency and therefore
shorten the period of the perf/NMI watchdog. With extreme Turbo-modes (3x
nominal frequency) the perf/NMI period is shorter than the hrtimer period
which leads to false positives.

A simple fix would be to shorten the hrtimer period, but that comes with
the side effect of more frequent hrtimer and softlockup thread wakeups,
which is not desired.

Implement a low pass filter, which checks the perf/NMI period against
kernel time. If the perf/NMI fires before 4/5 of the watchdog period has
elapsed then the event is ignored and postponed to the next perf/NMI.

That solves the problem and avoids the overhead of shorter hrtimer periods
and more frequent softlockup thread wakeups.

Marcel Holtmann 01d5e44ace Bluetooth: hci_bcm: Handle empty packet after firmware loading
The Broadcom controller on the Raspberry Pi3 sends an empty packet with
packet type 0x00 after launching the firmware. This will cause logging
of errors.

  Bluetooth: hci0: Frame reassembly failed (-84)

Since this seems to be an intented behaviour of the controller, handle
it gracefully by parsing that empty packet with packet type 0x00 and
then just simply report it as diagnostic packet.

With that change no errors are logging and the packet itself is actually
recorded in the Bluetooth monitor traces.

Darrick J. Wong 77aff8c764 xfs: don't leak quotacheck dquots when cow recovery
If we fail a mount on account of cow recovery errors, it's possible that
a previous quotacheck left some dquots in memory.  The bailout clause of
xfs_mountfs forgets to purge these, and so we leak them.  Fix that.

Darrick J. Wong 8204f8ddaa xfs: clear MS_ACTIVE after finishing log recovery
Way back when we established inode block-map redo log items, it was
discovered that we needed to prevent the VFS from evicting inodes during
log recovery because any given inode might be have bmap redo items to
replay even if the inode has no link count and is ultimately deleted,
and any eviction of an unlinked inode causes the inode to be truncated
and freed too early.

To make this possible, we set MS_ACTIVE so that inodes would not be torn
down immediately upon release.  Unfortunately, this also results in the
quota inodes not being released at all if a later part of the mount
process should fail, because we never reclaim the inodes.  So, set
MS_ACTIVE right before we do the last part of log recovery and clear it
immediately after we finish the log recovery so that everything
will be torn down properly if we abort the mount.
