Commit 2cbbb579bcbe ("regmap: Add the LZO cache support") introduced
'blksize' in regcache_lzo_read() and regcache_lzo_write(), that is
set but not used. Compiling with W=1 gives the following warnings,
fix them.
drivers/base/regmap/regcache-lzo.c: In function ‘regcache_lzo_read’:
drivers/base/regmap/regcache-lzo.c:239:9: warning: variable ‘blksize’ set but not used [-Wunused-but-set-variable]
size_t blksize, tmp_dst_len;
^
drivers/base/regmap/regcache-lzo.c: In function ‘regcache_lzo_write’:
drivers/base/regmap/regcache-lzo.c:278:9: warning: variable ‘blksize’ set but not used [-Wunused-but-set-variable]
size_t blksize, tmp_dst_len;
^
These are harmless warnings and are only being fixed to reduce the
noise with W=1 in the kernel.

Pull gcc plugins update from Kees Cook:
"This adds a new gcc plugin named "latent_entropy". It is designed to
extract as much possible uncertainty from a running system at boot
time as possible, hoping to capitalize on any possible variation in
CPU operation (due to runtime data differences, hardware differences,
SMP ordering, thermal timing variation, cache behavior, etc).
At the very least, this plugin is a much more comprehensive example
for how to manipulate kernel code using the gcc plugin internals"

Pull rdma qedr RoCE driver from Doug Ledford:
"Early on in the merge window I mentioned I had a backlog of new
drivers waiting to be reviewed and that, in addition to the hns-roce
driver, I wanted to get possible a couple more reviewed. I ended up
only having the time to complete one of the additional drivers.
During Dave Miller's pull request this go around, there were a series
of 9 patches to the QLogic qed net driver that add basic support for a
paired RoCE driver. That support is currently not functional because
it is missing the matching RoCE driver in the RDMA subsystem. I
managed to finish that review. However, because it goes against part
of Dave's net pull, and a part that was accepted a day or two after
the merge window opened, to apply cleanly it has to be applied to
either the tip of Dave's net branch, or as I did in this case, I just
applied it to your master after you had taken Dave's pull request."

Pull more rdma updates from Doug Ledford:
"This merge window was the first where Huawei had to try and coordinate
their patches between their net driver and their new roce driver
(similar to mlx4 and mlx5).
They didn't do horribly, but there were some issues (and we knew that
because they simply didn't know what to do in the beginning). As a
result, I had a set of patches that depended on some patches that
normally would have come to you via Dave's tree. Those patches have
been on netdev@ for a while, so I got Dave to give me his approval to
send them to you. As such, the other 29 patches I had behind them are
also now ready to go.
This catches the hns and hns-roce drivers up to current, and for
future patches we are working with them to get them up to speed on how
to do joint driver development so that they don't have these sorts of
cross tree dependency issues again. BTW, Dave gave me permission to
add his Acked-by: to the patches against the net tree, but I've had
this branch through 0day (but not linux-next since it was off by
itself) and I didn't want to rebase the series just to add Dave's ack
for the 8 patches in the net area.
Updates to the hns drivers:
- Small patch set for hns net driver that the roce patches depend on
- Various fixes to the hns-roce driver
- Add connection manager support to the hns-roce driver"

PCI changes for the v4.9 merge window:
"Here are some more changes I'd like to have in v4.9. There's one
small Tegra bug fix in the PHY poweroff path, which is only used in
failure paths.
The rest is all strictly cleanup that should make host bridge drivers
more readable, but shouldn't actually change any behavior.
Summary:
- use local struct device pointers in many host bridge drivers for
clarity
- remove unused platform data
- use generic DesignWare accessors
- misc cleanups: remove redundant structure entries and re-order
structure members to put comon generic fields first etc"

The desired_perf is an abstract performance number. Its value should
be in the range of [lowest perf, highest perf] of CPPC.
The correct calculation is
desired_perf = freq * cppc_highest_perf / cppc_dmi_max_khz
And cppc_cpufreq_set_target() returns if desired_perf is exactly
the same with the old perf.

The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.
If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.
If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.
Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.
This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,
e.g. phy_error().

Wiht the latest rework of the xen-netback driver, we get a warning
on ARM about the types passed into min():
drivers/net/xen-netback/rx.c: In function 'xenvif_rx_next_chunk':
include/linux/kernel.h:739:16: error: comparison of distinct pointer types lacks a cast [-Werror]
The reason is that XEN_PAGE_SIZE is not size_t here. There
is no actual bug, and we can easily avoid the warning using the
min_t() macro instead of min().

The gmac 4.x version has not extended descriptors
(that are available on 3.x instead of).
While initializing the PTP module, the advanced PTP was
enabled in case of extended descriptors. This cannot be
applied for 4.x version where only the hardware capability
register has to show if the feature is present.
Patch also adds some extra netdev_(debug/inof) to better

The software calculation of UDP checksum in Netvsc driver was
only handling IPv4 case. By using skb_checksum_help() instead
all protocols can be handled. Rearrange code to eliminate goto
and look like other drivers.
This is a temporary solution; recent versions of Window Server etc
do support UDP checksum offload, just need to do the appropriate negotiation
with host to validate before using. This will be done in later patch.
Please queue this for -stable as well.

If a VIF has been ready for rx_stall_timeout (60s by default) and an
Rx ring is drained of all requests an Rx stall will be incorrectly
detected. When this occurs and the guest Rx queue is empty, the Rx
ring's event index will not be set and the frontend will not raise an
event when new requests are placed on the ring, permanently stalling
the VIF.
This is a regression introduced by eb1723a29b9a7 (xen-netback:
refactor guest rx).
Fix this by reinstating the setting of queue->last_rx_time when
placing a packet onto the guest Rx ring.

I am hitting this in mlx5:
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function
reclaim_pages_cmd.clone.0:
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:346: error: call
to __compiletime_assert_346 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_out, pas[i]) % 64

to __compiletime_assert_291 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_in, pas[i]) % 64
Problem is that this is doing a BUILD_BUG_ON on a non-constant
expression because of trying to take offset of pas[i] in the
structure.
Fix is to create MLX5_ARRAY_SET64 that takes an additional argument
that is the field index to separate between BUILD_BUG_ON on the array
constant field and the indexed field to assign the value to.
There are two callers of MLX5_SET64 that are trying to get a variable
offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i'
as the arguments to use in the offset check and the indexed value
assignment.

The Quectel EC21 and EC25 need the same "set DTR" request as devices
based on the MDM9230 chipset, but has no USB3 support. Our best guess
is that the "set DTR" functionality depends on chipset and/or
baseband firmware generation. But USB3 is still an optional feature.
Since we cannot enable this unconditionally for all older devices, and
there doesn't appear to be anything we can use in the USB descriptors
to identify these chips, we are forced to use a device specific quirk
flag.

It is useful to be able to see the hash configuration when running tests.
This patch adds a debugfs node for that purpose.
The original version of this patch (commit c0c64c152389) was reverted due
to build failures caused by a conflict with commit 0364a8824c02
("xen-netback: switch to threaded irq for control ring"). This new version
of the patch is nearly identical to the original, the only difference
being that creation of the debugfs node is predicated on 'ctrl_irq' being
non-zero rather then the now non-existent 'ctrl_task'.
