Core changes:
- Augment fwnode_get_named_gpiod() to configure the GPIO pin
immediately after requesting it like all other APIs do.
This is a treewide change also updating all users.
- Pass a GPIO label down to gpiod_request() from
fwnode_get_named_gpiod(). This makes debugfs and the userspace
ABI correctly reflect the current in-kernel consumer of a pin
taken using this abstraction. This is a treewide change also
updating all users.
- Rename devm_get_gpiod_from_child() to
devm_fwnode_get_gpiod_from_child() to reflect the fact that this
function is operating on a fwnode object. This is a treewide
change also updating all users.
- Make it possible to take multiple GPIOs in a single hog of device
tree hogs.
- The refactorings switching GPIO chips to use the .set_config()
callback using standard pin control properties and providing
a backend into the pin control subsystem that were also merged
into the pin control tree naturally appear here too.
Testing instrumentation:
- A whole slew of cleanups and improvements to the mockup GPIO
driver. We now have an extended userspace test exercising the
subsystem, and we can inject interrupts etc from userspace
to fully test the core GPIO functionality.
New drivers:
- New driver for the Cortina Systems Gemini GPIO controller.
- New driver for the Exar XR17V352/354/358 chips.
- New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
Driver changes:
- RCAR: set the irqchip parent device, add fine-grained runtime
PM support.
- pca953x: support optional RESET control line on the chip.
- DaVinci: cleanups and simplifications. Add support for multiple
instances.
- .set_multiple() and naming of lines on more or less all of the
ISA/PCI GPIO controllers.
- mcp23s08: refactored to use regmap as a first step to further
rewrites and modernizations.

fwnode_get_named_gpiod(). This makes debugfs and the userspace ABI
correctly reflect the current in-kernel consumer of a pin taken
using this abstraction. This is a treewide change also updating all
users.
- Rename devm_get_gpiod_from_child() to
devm_fwnode_get_gpiod_from_child() to reflect the fact that this
function is operating on a fwnode object. This is a treewide change
also updating all users.
- Make it possible to take multiple GPIOs in a single hog of device
tree hogs.
- The refactorings switching GPIO chips to use the .set_config()
callback using standard pin control properties and providing a
backend into the pin control subsystem that were also merged into
the pin control tree naturally appear here too.
Testing instrumentation:
- A whole slew of cleanups and improvements to the mockup GPIO
driver. We now have an extended userspace test exercising the
subsystem, and we can inject interrupts etc from userspace to fully
test the core GPIO functionality.
New drivers:
- New driver for the Cortina Systems Gemini GPIO controller.
- New driver for the Exar XR17V352/354/358 chips.
- New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
Driver changes:
- RCAR: set the irqchip parent device, add fine-grained runtime PM
support.
- pca953x: support optional RESET control line on the chip.
- DaVinci: cleanups and simplifications. Add support for multiple
instances.
- .set_multiple() and naming of lines on more or less all of the
ISA/PCI GPIO controllers.
- mcp23s08: refactored to use regmap as a first step to further
rewrites and modernizations"

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Revisit warning logic when not applying default helper assignment.
Jiri Kosina considers we are breaking existing setups and not warning
our users accordinly now that automatic helper assignment has been
turned off by default. So let's make him happy by spotting the warning
by when we find a helper but we cannot attach, instead of warning on the
former deprecated behaviour. Patch from Jiri Kosina.
2) Two patches to fix regression in ctnetlink interfaces with
nfnetlink_queue. Specifically, perform more relaxed in CTA_STATUS
and do not bail out if CTA_HELP indicates the same helper that we
already have. Patches from Kevin Cernekee.
3) A couple of bugfixes for ipset via Jozsef Kadlecsik. Due to wrong
index logic in hash set types and null pointer exception in the
list:set type.
4) hashlimit bails out with correct userspace parameters due to wrong
arithmetics in the code that avoids "divide by zero" when
transforming the userspace timing in milliseconds to token credits.
Patch from Alban Browaeys.
5) Fix incorrect NFQA_VLAN_MAX definition, patch from
Ken-ichirou MATSUZAWA.
6) Don't not declare nfnetlink batch error list as static, since this
may be used by several subsystems at the same time. Patch from
Liping Zhang.

When creating EQs to handle CQ completion events for the PF
or for VFs, we create enough EQE entries to handle completions
for the max number of CQs that can use that EQ.
When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource tracker).
Therefore, when creating an EQ, the number of EQE entries that the VF
should request for that EQ is the CQ quota value (and not the total
number of CQs available in the FW).
Under SRIOV, the PF, also must use its CQ quota, because
the resource tracker also controls how many CQs the PF can obtain.
Using the FW total CQs instead of the CQ quota when creating EQs resulted
wasting MTT entries, due to allocating more EQEs than were needed.

In the VF driver, module parameter mlx4_log_num_mgm_entry_size was
mistakenly overwritten -- and in a manner which overrode the
device-managed flow steering option encoded in the parameter.
log_num_mgm_entry_size is a global module parameter which
affects all ConnectX-3 PFs installed on that host.
If a VF changes log_num_mgm_entry_size, this will affect all PFs
which are probed subsequent to the change (by disabling DMFS for
those PFs).

====================
Mellanox mlx5e fixes for 4.11-rc1
This series includes some important bug fixes for mlx5e driver.
Three misc fixes:
From Mohamad, compilation fix on s390 system
From Me, A fix for driver unload when switchdev mode is on.
From Tariq, HW LRO frag size optimization for when build_skb is not used
(striding RQ mode).
Three CQE compression related fixes:
Two fixes from Tariq and I, to correctly setup CQE compression
parameters on driver load and on arbitrary user modifications.
Last patch, fixes a very critical issue that was originally reported
by Tom, where the driver reported csum errors or even page ref issues
for when cqe compression is enabled and rapidly active.
For your convenience this series was generated on top of net-next branch:
005c3490e9 ('Revert "ath10k: Search SMBIOS for OEM board file extension"')
for -stable:
net/mlx5e: Register/unregister vport representors on interface (for kernel >= 4.9)
net/mlx5e: Do not reduce LRO WQE size when not using build_skb (for kernel >= 4.9)
net/mlx5e: Fix broken CQE compression initialization (for kernel >= 4.9)
net/mlx5e: Update MPWQE stride size when modifying CQE compress state (for kernel >= 4.7)
net/mlx5e: Fix wrong CQE decompression (for kernel >= 4.7)
====================

In cqe compression with striding RQ, the decompression of the CQE field
wqe_counter was done with a wrong wraparound value.
This caused handling cqes with a wrong pointer to wqe (rx descriptor)
and creating SKBs with wrong data, pointing to wrong (and already consumed)
strides/pages.
The meaning of the CQE field wqe_counter in striding RQ holds the
stride index instead of the WQE index. Hence, when decompressing
a CQE, wqe_counter should have wrapped-around the number of strides
in a single multi-packet WQE.
We dropped this wrap-around mask at all in CQE decompression of striding
RQ. It is not needed as in such cases the CQE compression session would
break because of different value of wqe_id field, starting a new
compression session.
Tested:
ethtool -K ethxx lro off/on
ethtool --set-priv-flags ethxx rx_cqe_compress on
super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D
verified no csum errors and no page refcount issues.

When the admin enables/disables cqe compression, updating
mpwqe stride size is required:
CQE compress ON ==> stride size = 256B
CQE compress OFF ==> stride size = 64B
This is already done on driver load via mlx5e_set_rq_type_params, all we
need is just to call it on arbitrary admin changes of cqe compression
state via priv flags or when changing timestamping state
(as it is mutually exclusive with cqe compression).
This bug introduces no functional damage, it only makes cqe compression
occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.
Tested:
ethtool --set-priv-flags ethxx rx_cqe_compress on
pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
verify `ethtool -S ethxx | grep compress` are advancing more often
(rapidly)

Some of RQ type parameters are derived from CQE compression state flag,
CQE compression flag was initialized only after RQ type parameters
setup. This leads to load RQ with stride size smaller than what we
want for when CQE compression is on.

occur less often, since in ConnectX4-LX CQE compression is performed
only on packets smaller than stride size.
Fix this by marking default status of CQE compression in PFLAG prior to
calling mlx5e_set_rq_priv_params(), as it inits some fields based on it.
Tested:
load driver on systems where rx CQE compress will be on (MH)
pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6)
verify `ethtool -S ethxx | grep compress` are advancing more often
(rapidly)

Currently vport representors are added only on driver load and removed on
driver unload. Apparently we forgot to handle them when we added the
seamless reset flow feature. This caused to leave the representors
netdevs alive and active with open HW resources on pci shutdown and on
error reset flows.
To overcome this we move their handling to interface attach/detach, so
they would be cleaned up on shutdown and recreated on reset flows.

Pull printk updates from Petr Mladek:
- Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven
Rostedt as the printk reviewer. This idea came up after the
discussion about printk issues at Kernel Summit. It was formulated
and discussed at lkml[1].
- Extend a lock-less NMI per-cpu buffers idea to handle recursive
printk() calls by Sergey Senozhatsky[2]. It is the first step in
sanitizing printk as discussed at Kernel Summit.
The change allows to see messages that would normally get ignored or
would cause a deadlock.
Also it allows to enable lockdep in printk(). This already paid off.
The testing in linux-next helped to discover two old problems that
were hidden before[3][4].
- Remove unused parameter by Sergey Senozhatsky. Clean up after a past
change.

Merge tag 'modules-for-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules updates from Jessica Yu:
"Summary of modules changes for the 4.11 merge window:
- A few small code cleanups
- Add modules git tree url to MAINTAINERS"
* tag 'modules-for-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux:
MAINTAINERS: add tree for modules
module: fix memory leak on early load_module() failures
module: Optimize search_module_extables()
modules: mark __inittest/__exittest as __maybe_unused
livepatch/module: print notice of TAINT_LIVEPATCH
module: Drop redundant declaration of struct module
At present, Tying the first_num size to NCHUNKS_ORDER is confusing. the
number of chunks is completely unrelated to the number of buddies.
The patch limits the first_num to actual range of possible buddy indexes.
and that is more reasonable and obvious without functional change.
