ACPI SSCN/FMCN methods were originally added because then the platform can
provide the most accurate HCNT/LCNT values to the driver. However, this
seems not to be true for Dell Inspiron 7348 where using these causes the
touchpad to fail in boot:
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: controller timed out
The values received from ACPI are (in fast mode):
HCNT: 72
LCNT: 160
this translates to following timings (input clock is 100MHz on Broadwell):
tHIGH: 720 ns (spec min 600 ns)
tLOW: 1600 ns (spec min 1300 ns)
Bus period: 2920 ns (assuming 300 ns tf and tr)
Bus speed: 342.5 kHz
Both tHIGH and tLOW are within the I2C specification.
The calculated values when ACPI parameters are not used are (in fast mode):
HCNT: 87
LCNT: 159
which translates to:
tHIGH: 870 ns (spec min 600 ns)
tLOW: 1590 ns (spec min 1300 ns)
Bus period 3060 ns (assuming 300 ns tf and tr)
Bus speed 326.8 kHz
These values are also within the I2C specification.
Since both ACPI and calculated values meet the I2C specification timing
requirements it is hard to say why the touchpad does not function properly
with the ACPI values except that the bus speed is higher in this case (but
still well below the max 400kHz).
Solve this by adding DMI quirk to the driver that disables using ACPI
parameters on this particulare machine.

This commit prevents from sending "big" file using Bluetooth.
When sending a lot of data quickly through the Bluetooth interface, and
after a variable amount of data sent, transfer fails with error:

We received several reports of systems rebooting and powering on
after an attempted shutdown. Testing showed that setting
XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT
quirk allowed the system to shutdown as expected for LynxPoint-LP
xHCI controllers. Set the quirk back.
Note that the quirk was originally introduced for LynxPoint and
LynxPoint-LP just for this same reason. See:
commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell")
It was later limited to only concern HP machines as it caused
regression on some machines, see both bug and commit:
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171
commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP machines")
Later it was discovered that the powering on after shutdown
was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP
machine suffered from spontaneous resume from S3 (which should
not be related to the SPURIOUS_WAKEUP quirk at all). An attempt
to fix this then removed the SPURIOUS_WAKEUP flag usage completely.
commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell")
Current understanding is that LynxPoint-LP (Haswell ULT) machines
need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and
plain Lynxpoint (Haswell) machines may _not_ have the quirk
set otherwise they again will restart.

If a host fails to wake up a isochronous SuperSpeed device from U1/U2
in time for a isoch transfer it will generate a "No ping response error"
Host will then move to the next transfer descriptor.
Handle this case in the same way as missed service errors, tag the
current TD as skipped and handle it on the next transfer event.

If the difference is big enough between the bytes asked and received
in a bulk transfer we can get a short transfer event pointing to a TRB in
the middle of the TD. We don't want to handle the TD yet as we will anyway
receive a new event for the last TRB in the TD.
Hold off from finishing the TD and removing it from the list until we
receive an event for the last TRB in the TD

Commit 6afdb859b710 ("mm: do not ignore mapping_gfp_mask in page cache
allocation paths") has caught some users of hardcoded GFP_KERNEL used in
the page cache allocation paths. This, however, wasn't complete and
there were others which went unnoticed.
Dave Chinner has reported the following deadlock for xfs on loop device:
: With the recent merge of the loop device changes, I'm now seeing
: XFS deadlock on my single CPU, 1GB RAM VM running xfs/073.
:
: The deadlocked is as follows:
:
: kloopd1: loop_queue_read_work
: xfs_file_iter_read
: lock XFS inode XFS_IOLOCK_SHARED (on image file)
: page cache read (GFP_KERNEL)
: radix tree alloc
: memory reclaim
: reclaim XFS inodes
: log force to unpin inodes
: <wait for log IO completion>
:
: xfs-cil/loop1: <does log force IO work>
: xlog_cil_push
: xlog_write
: <loop issuing log writes>
: xlog_state_get_iclog_space()
: <blocks due to all log buffers under write io>
: <waits for IO completion>
:
: kloopd1: loop_queue_write_work
: xfs_file_write_iter
: lock XFS inode XFS_IOLOCK_EXCL (on image file)
: <wait for inode to be unlocked>
:
: i.e. the kloopd, with it's split read and write work queues, has
: introduced a dependency through memory reclaim. i.e. that writes
: need to be able to progress for reads make progress.
:
: The problem, fundamentally, is that mpage_readpages() does a
: GFP_KERNEL allocation, rather than paying attention to the inode's
: mapping gfp mask, which is set to GFP_NOFS.
:
: The didn't used to happen, because the loop device used to issue
: reads through the splice path and that does:
:
: error = add_to_page_cache_lru(page, mapping, index,
: GFP_KERNEL & mapping_gfp_mask(mapping));
This has changed by commit aa4d86163e4 ("block: loop: switch to VFS
ITER_BVEC").
This patch changes mpage_readpage{s} to follow gfp mask set for the
mapping. There are, however, other places which are doing basically the
same.
lustre:ll_dir_filler is doing GFP_KERNEL from the function which
apparently uses GFP_NOFS for other allocations so let's make this
consistent.
cifs:readpages_get_pages is called from cifs_readpages and
__cifs_readpages_from_fscache called from the same path obeys mapping
gfp.
ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well
regardless it uses mapping_gfp_mask for the page allocation.
ext4_mpage_readpages is the called from the page cache allocation path
same as read_pages and read_cache_pages
As I've noticed in my previous post I cannot say I would be happy about
sprinkling mapping_gfp_mask all over the place and it sounds like we
should drop gfp_mask argument altogether and use it internally in
__add_to_page_cache_locked that would require all the filesystems to use
mapping gfp consistently which I am not sure is the case here. From a
quick glance it seems that some file system use it all the time while
others are selective.

This covers only the simplest case - an object size sized write, but
it's still useful in tiering setups when EC is used for the base tier
as writefull op can be proxied, saving an object promotion.
Even though updating ceph_osdc_new_request() to allow writefull should
just be a matter of fixing an assert, I didn't do it because its only
user is cephfs. All other sites were updated.
Reflects ceph.git commit 7bfb7f9025a8ee0d2305f49bf0336d2424da5b5b.

Commit 30e2bc08b2bb ("Revert "block: remove artifical max_hw_sectors
cap"") restored a clamp on max_sectors. It's now 2560 sectors instead
of 1024, but it's not good enough: we set max_hw_sectors to rbd object
size because we don't want object sized I/Os to be split, and the
default object size is 4M.
So, set max_sectors to max_hw_sectors in rbd at queue init time.

When we create a generic MSI domain, that MSI_FLAG_USE_DEF_CHIP_OPS
is set, and that any of .mask or .unmask are NULL in the irq_chip
structure, we set them to pci_msi_[un]mask_irq.
This is a bad idea for at least two reasons:
- PCI_MSI might not be selected, kernel fails to build (yes, this is
legitimate, at least on arm64!)
- This may not be a PCI/MSI domain at all (platform MSI, for example)
Either way, this looks wrong. Move the overriding of mask/unmask to
the PCI counterpart, and panic is any of these two methods is not
set in the core code (they really should be present).

Pull rdma updates from Doug Ledford:
"We have four batched up patches for the current rc kernel.
Two of them are small fixes that are obvious.
One of them is larger than I would like for a late stage rc pull, but
we found an issue in the namespace lookup code related to RoCE and
this works around the issue for now (we allow a lookup with a
namespace to succeed on RoCE since RoCE namespaces aren't implemented
yet). This will go away in 4.4 when we put in support for namespaces
in RoCE devices.
The last one is large in terms of lines, but is all legal and no
functional changes. Cisco needed to update their files to be more
specific about their license. They had intended the files to be dual
licensed as GPL/BSD all along, and specified that in their module
license tag, but their file headers were not up to par. They
contacted all of the contributors to get agreement and then submitted
a patch to update the license headers in the files.
Summary:
- Work around connection namespace lookup bug related to RoCE
- Change usnic license to Dual GPL/BSD (was intended to be that way
all along, but wasn't clear, permission from contributors was
chased down)
- Fix an issue between NFSoRDMA and mlx5 that could cause an oops
- Fix leak of sendonly multicast groups"

Resources are reallocated for requeued commands, so unmap and release
the iod for the failed command.
It's a pretty bad memory leak and causes a kernel hang if you remove a
drive because of a busy dma pool. You'll get messages spewing like this:
nvme 0000:xx:xx.x: dma_pool_destroy prp list 256, ffff880420dec000 busy
and lock up pci and the driver since removal never completes while
holding a lock.

When ib_cache_gid_set_default_gid is called from several threads,
updating the table could make find_gid fail, therefore a negative
index will be retruned and an invalid table entry will be used.
Locking find_gid as well fixes this problem.

Merge "Fixes for omap against v4.3-rc5" from Tony Lindgren:
- Regulator fix for beagle-x15 to fix HDMI without a SD card being
inserted
- GPMC fix for showing proper timings and to allow enabling debug
options that somehow was unselectable earlier
- Add minimal documentation for new MMC1 dependency on
REGULATOR_PBIAS as it may not be obvious for people with
targeted .config files

When PMU context is migrating between CPUs, interrupt affinity is set as
well. Only this should not happen when the CCN interrupt is not being
used at all (the driver is using a hrtimer tick instead).

Under certain conditions EMAD responses can be returned from the device
even before setting trans_active. This will cause the EMAD Rx listener
to drop the EMAD response - as there are no active transactions - and
timeouts will be generated.
Fix this by setting trans_active before transmitting the EMAD skb.

Some logics actually relying on the existence of FADT, currently relies on
the number of loaded tables. This false dependency can easily trigger
regressions. One of them has been introduced by commit 8ec3f459073e
(ACPICA: Tables: Fix global table list issues by removing fixed table).
The commit changing the fixed table indexes results in the change of FADT
table index, originally, it was 3 (thus the installed table count should be
greater than 4), while currently it is 0 (and the installed table count may
be 3).
This patch fixes this regression by cleaning up the code. Lv Zheng.

This partially reverts commit eca61c9ff2588e1df373e61078e1874976315839.
Thomas reports that it causes regressions on Armada XP devices.
This is because of_clk_get_parent_name() relies on the property
'clock-output-names' to resolve the name of a clock's parent,
without trying to get the clock from the framework and call
__clk_get_name(). Given that Armada XP devices don't have the
'clock-output-names' property, of_clk_get_parent_name() returns
the name of the node which doesn't match the actual parent
clock's name at all, causing CPU clocks to never link up with
their parents.
