Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.
In particular, of_mdiobus_register can fail before doing anything
interesting, so one could view it as a no-op from the reference count
point of view.

Macvlan always turns on offload features that have sofware
fallback (NETIF_GSO_SOFTWARE). This allows much higher guest-guest
communications over macvtap.
However, macvtap does not turn on these features for vlan tagged traffic.
As a result, depending on the HW that mactap is configured on, the
performance of guest-guest communication over a vlan is very
inconsistent. If the HW supports TSO/UFO over vlans, then the
performance will be fine. If not, the the performance will suffer
greatly since the VM may continue using TSO/UFO, and will force the host
segment the traffic and possibly overlow the macvtap queue.
This patch adds the always on offloads to vlan_features. This
makes sure that any vlan tagged traffic between 2 guest will not
be segmented needlessly.

If a vma is already bound to a ppgtt, we incorrectly call
allocate_va_range again when doing a PIN_UPDATE, which will result in
over accounting within our paging structures, such that when we do
unbind something we don't actually destroy the structures and end up
inadvertently recycling them. In reality this probably isn't too bad,
but once we start touching PDEs and PDPEs for 64K/2M/1G pages this
apparent recycling will manifest into lots of really, really subtle
bugs.

Turns out our skills in decoding the CLKCFG register weren't good
enough. On this particular elk the answer we got was 400 MHz when
in reality the clock was running at 266 MHz, which then caused us
to program a bogus AUX clock divider that caused all AUX communication
to fail.
Sadly the docs are now in bit heaven, so the fix will have to be based
on empirical evidence. Using another elk machine I was able to frob
the FSB frequency from the BIOS and see how it affects the CLKCFG
register. The machine seesm to use a frequency of 266 MHz by default,
and fortunately it still boot even with the 50% CPU overclock that
we get when we bump the FSB up to 400 MHz.
It turns out the actual FSB frequency and the register have no real
link whatsoever. The register value is based on some straps or something,
but fortunately those too can be configured from the BIOS on this board,
although it doesn't seem to respect the settings 100%. In the end I was
able to derive the following relationship:
BIOS FSB / strap | CLKCFG
-------------------------
200 | 0x2
266 | 0x0
333 | 0x4
400 | 0x4
So only the 200 and 400 MHz cases actually match how we're currently
decoding that register. But as the comment next to some of the defines
says, we have been just guessing anyway.
So let's fix things up so that at least the 266 MHz case will work
correctly as that is actually the setting used by both the buggy
machine and my test machine.
The fact that 333 and 400 MHz BIOS settings result in the same register
value is a little disappointing, as that means we can't tell them apart.
However, according to the gmch datasheet for both elk and ctg 400 Mhz is
not even a supported FSB frequency, so I'm going to make the assumption
that we should decode it as 333 MHz instead.

Not calling pm_runtime_enable() means that runtime PM can't be
enabled at all via sysfs. So we definitely need to call it
from somewhere.
Calling it from the driver seems like a bad idea because it
would have to be paired with a pm_runtime_disable() at driver
unload time, otherwise the core gets upset. Also if there's
no LPE audio driver loaded then we couldn't runtime suspend
i915 either.
So it looks like a better plan is to call it from i915 when
we register the platform device. That seems to match how
pci generally does things. I cargo culted the
pm_runtime_forbid() and pm_runtime_set_active() calls from
pci as well.
The exposed runtime PM API is massive an thorougly misleading, so
I don't actually know if this is how you're supposed to use the API
or not. But it seems to work. I can now runtime suspend i915 again
with or without the LPE audio driver loaded, and reloading the
LPE audio driver also seems to work.
Note that powertop won't auto-tune runtime PM for platform devices,
which is a little annoying. So I'm not sure that leaving runtime
PM in "on" mode by default is the best choice here. But I've left
it like that for now at least.
Also remove the comment about there not being much benefit from
LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime
PM, which will also block s0ix, and that could have a measurable
impact on power consumption.

The sequence in glk_dsi_device_ready() enters ULPS then waits until it is
*not* active to then disable it. The correct sequence according to the
spec is to enter ULPS then wait until the GLK_ULPS_NOT_ACTIVE bit is
zero, i.e., ULPS is active, and then disable ULPS.
Fixing the condition gets rid of the following spurious error messages:

IO tracking used to throttle writebacks when the origin device is busy.
Even if all the IO is going to the fast device, writebacks can
significantly degrade performance. So track all IO to gauge whether the
cache is busy or not.
Otherwise, synthetic IO tests (e.g. fio) that might send all IO to the
fast device wouldn't cause writebacks to get throttled.

The recent conversion to the hotplug state machine missed that the original
hotplug notifiers did not execute in the frozen state, which is used on
suspend on resume.
This does not matter on single socket machines, but on multi socket systems
this breaks when the device for a non-boot socket is removed when the last
CPU of that socket is brought offline. The device removal locks up the
machine hard w/o any debug output.
Prevent executing the hotplug callbacks when cpuhp_tasks_frozen is true.
Thanks to Tommi for providing debug information patiently while I failed to
spot the obvious.

case where the recent fixes to arch_copy_from_iter_pmem() missed a
condition where we strand dirty data in the cache. This is tagged
for -stable and will also be included in the rework of the pmem api

initializing a BTT (atomic sector update driver) instance on a pmem

- Ross noticed that the dax_device + dax_operations conversion broke

If an array consists of two drives and the first drive has the bad
block, the read request to the region overlapping the bad block chooses
the same disk (with bad block) as device to read from over and over and
the request gets stuck. If the first disk only partially overlaps with
bad block, it becomes a candidate ("best disk") for shorter range of
sectors. The second disk is capable of reading the entire requested
range and it is updated accordingly, however it is not recorded as a
best device for the request. In the end the request is sent to the first
disk to read entire range of sectors. It fails and is re-tried in a
moment but with the same outcome.
Actually it is quite likely scenario but it had little exposure in my
test until commit 715d40b93b10 ("md/raid1: add failfast handling for
reads.") removed preference for idle disk. Such scenario had been
passing as second disk was always chosen when idle.
Reset a candidate ("best disk") to read from if disk can read entire
range. Do it only if other disk has already been chosen as a candidate
for a smaller range. The head position / disk type logic will select
the best disk to read from - it is fine as disk with bad block won't be
considered for it.

Pull SCSI target updates from Nicholas Bellinger:
"Things were a lot more calm than previously expected. It's primarily
fixes in various areas, with most of the new functionality centering
around TCMU backend driver work that Xiubo Li has been driving.
Here's the summary on the feature side:
- Make T10-PI verify configurable for emulated (FILEIO + RD) backends
(Dmitry Monakhov)
- Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
(Bryant Ly + MNC)
- Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
- Add TCMU support for global block data pool (Xiubo Li + MNC)
and on the bug-fix side:
- Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
failures (Gary Guo + nab)
- Fix iscsi-target hang with explicitly changing per NodeACL
CmdSN number depth with concurrent login driven session
reinstatement. (Gary Guo + nab)
- Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
- Fix target-core/FILEIO zero length handling (Bart Van Assche)
Also, there was an OOPs introduced with the WRITE_VERIFY changes that
I ended up reverting at the last minute, because as not unusual Bart
and I could not agree on the fix in time for -rc1. Since it's specific
to a conformance test, it's been reverted for now.
There is a separate patch in the queue to address the underlying
control CDB write overflow regression in >= v4.3 separate from the
WRITE_VERIFY revert here, that will be pushed post -rc1"

There are several paths in vmxnet3, where settings changes cause the
adapter to be brought down and back up (vmxnet3_set_ringparam among
them). Should part of the reset operation fail, these paths call
vmxnet3_force_close, which enables all napi instances prior to calling
dev_close (with the expectation that vmxnet3_close will then properly
disable them again). However, vmxnet3_force_close neglects to clear
VMXNET3_STATE_BIT_QUIESCED prior to calling dev_close. As a result
vmxnet3_quiesce_dev (called from vmxnet3_close), returns early, and
leaves all the napi instances in a enabled state while the device itself
is closed. If a device in this state is activated again, napi_enable
will be called on already enabled napi_instances, leading to a BUG halt.
The fix is to simply enausre that the QUIESCED bit is cleared in
vmxnet3_force_close to allow quesence to be completed properly on close.

Currently, sync of raid456 array cannot make progress when hitting
data in writeback r5cache.
This patch fixes this issue by flushing cached data of the stripe
before processing the sync request. This is achived by:
1. In handle_stripe(), do not set STRIPE_SYNCING if the stripe is
in write back cache;
2. In r5c_try_caching_write(), handle the stripe in sync with write
through;
3. In do_release_stripe(), make stripe in sync write out and send
it to the state machine.

For the raid456 with writeback cache, when journal device failed during
normal operation, it is still possible to persist all data, as all
pending data is still in stripe cache. However, it is necessary to handle
journal failure gracefully.
During journal failures, the following logic handles the graceful shutdown
of journal:
1. raid5_error() marks the device as Faulty and schedules async work
log->disable_writeback_work;
2. In disable_writeback_work (r5c_disable_writeback_async), the mddev is
suspended, set to write through, and then resumed. mddev_suspend()
flushes all cached stripes;
3. All cached stripes need to be flushed carefully to the RAID array.
This patch fixes issues within the process above:
1. In r5c_update_on_rdev_error() schedule disable_writeback_work for
journal failures;
2. In r5c_disable_writeback_async(), wait for MD_SB_CHANGE_PENDING,
since raid5_error() updates superblock.
3. In handle_stripe(), allow stripes with data in journal (s.injournal > 0)
to make progress during log_failed;
4. In delay_towrite(), if log failed only process data in the cache (skip
new writes in dev->towrite);
5. In __get_priority_stripe(), process loprio_list during journal device
failures.
6. In raid5_remove_disk(), wait for all cached stripes are flushed before
calling log_exit().

Add a new Kconfig option to enable/disable the extra warnings
from the vblank evade code. For now we'll keep the warning
about an actually missed vblank always enabled as that can have
an actual user visible impact. But if we miss the deadline
othrwise there's no real need to bother the user with that.
We'll want these warnings enabled during development however
so that we can catch regressions.
Based on the reports it looks like this is still very easy
to hit on SKL, so we have more work ahead of us to optimize
the crtiical section further.
