To prevent a race between the TX DMA engine and the CPU the writing of the
first transmit descriptor must be deferred until all following descriptors
have been updated. The network card may otherwise start transmitting before
all packet descriptors are set up correctly, which leads to data corruption
or an aborted transmit operation.
This deferral is already done in the non-TSO TX path, implement it also in
the TSO TX path.

The TX DMA engine requires that buffers with a size of 8 bytes or smaller
must be 64 bit aligned. This requirement may be violated when doing TSO,
as in this case larger skb frags can be broken up and transmitted in small
parts with then inappropriate alignment.
Fix this by checking for proper alignment before handing a buffer to the
DMA engine. If the data is misaligned realign it by copying it into the
TSO header data area.

If a gigabit ethernet PHY is connected to a fast ethernet MAC,
then it can detect 1000 support from the partner but not use it.
This results in a forced speed of 1000 and RX/TX failure.
Check for 1000BASE-T support and then check the advertisement
configuration before setting the MAC speed to 1000mbit.

Link interrupts are enabled in init_umac(), which is too early for us to
process them since we do not yet have a valid PHY device pointer. On
BCM7425 chips for instance, we will crash calling phy_mac_interrupt()
because phydev is NULL.
Fix this by moving the link interrupts enabling in
bcmgenet_netif_start(), under a specific function:
bcmgenet_link_intr_enable() and while at it, update the comments
surrounding the code.

Before lightweight tunnels existed, it really didn't make sense to
create a tunnel that was not fully specified, such as without a
destination IP address - the resulting packets would go nowhere.
However, with lightweight tunnels, the opposite is true - it doesn't
make sense to require this information when it will be provided later
on by the route. This loosens the requirements for this information.
An alternative would be to allow the relaxed version only when
COLLECT_METADATA is enabled. However, since there are several
variations on this theme (such as NBMA tunnels in GRE), just dropping
the restrictions seems the most consistent across tunnels and with
the existing configuration.

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.

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).

This is a workaround for KNL platform, where in some cases MPERF counter
will not have updated value before next read of MSR_IA32_MPERF. In this
case divide by zero will occur. This change ignores current sample for
busy calculation in this case.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
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"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma:
IB/ipoib: For sendonly join free the multicast group on leave
IB/cma: Accept connection without a valid netdev on RoCE

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.

Commit ba2bbfbf6307 (PM / Domains: Remove intermediate states from the
power off sequence) changed the power off sequence in genpd. That also
required some updates regarding the validation of latency constraints in
the genpd governor. Unfortunate that wasn't covered, so let's fix this.
From a runtime PM and latency point of view, we need to consider the worst
case scenario while validating latency constraints. That's typically when
a call to pm_runtime_get_sync() needs to wait for a ongoing runtime
suspend operation to be carried out, as it then also needs to wait for the
device to be runtime resumed again.
The above mentioned commit made the genpd governor's ->stop_ok() callback
responsible of validating genpd's device's runtime suspend/resume latency.
In other words, the constraint needs to be validated towards the relevant
latencies present in genpd's ->runtime_suspend|resume() callbacks.
Earlier, that included latencies from the ->stop|start() callbacks, but as
->save|restore_state() are now also being invoked from genpd's
->runtime_suspend|resume() and to comply with the worst case scenario,
let's take also those latencies into account.
