Marvell chips with an SMI PHY access in Global 2 registers handle both
Clause 22 and Clause 45 of IEEE 802.3.
The 88E6390 family has addition bits to target the internal or external
PHYs connected to the device, and a Setup function in addition to the
default (register) Access function.
Prefix the SMI PHY Command and Data registers macros, implement clear
helpers for Clause 22 and 44 Access functions, rename variable to match
the SMI and switch vocabulary (device and register addresses for Clause
22 and port and device class for Clause 45.)
Finally do not use complex macros but simple 16-bit mask to document the
registers organization.

Some Marvell chips have an Ingress Rate Limit unit. But the command
values slightly differs between models: 88E6352 use 3-bit for operations
while 88E6390 use different 2-bit operations.
This commit kills the IRL flags in favor of a new operation implementing
the "Init all resources to the initial state" operation.
This fixes the operation of 88E6390 family where 0x1000 means Read the
selected resource 0, register 0 on port 16, instead of init all.
A mv88e6xxx_irl_setup helper is added to wrap the operation call.

Pali Rohár found that there have some wmi query/evaluation
code that they used 'one' as the first WMI instance number.
But the number is indexed from zero that it's must less than
the instance_count in _WDG.
This patch changes those instance number from one to zero.

net-next: stmmac: dwmac-sun8i: add support for V3s
Allwinner V3s features an EMAC like the on in H3, but without external MII
interfaces, so being not able really to use RMII/RGMII.
And it has a different default value of syscon (0x38000 instead of 0x58000
on H3), which shows a problem that the EMAC clock freq should be 24MHz.
(Both H3 and V3s SoCs doesn't have extra xtal input for EPHY, and the
main xtal is 24MHz. The default value of H3 is set to 24MHz, but the V3s
default value is set to 25MHz).
First two patches are device tree binding patches, the third forces
the frequency to 24MHz and the fourth really add the V3s support.

Allwinner V3s SoC has an Ethernet MAC and an internal PHY like the ones
in H3 SoC, however the MAC has no external *MII interfaces available at
GPIOs, thus only MII connection to internal PHY is supported.
Add this variant of EMAC to dwmac-sun8i driver.
The default value of the syscon EMAC-related register seems to have
changed from H3, but it seems to be a harmless change.

The EPHY control part of the EMAC syscon register has a bit called
CLK_SEL. On the datasheet it says that if it's 0 the EPHY clock is 25MHz
and if it's 1 the clock is 24MHz.
However, according to the datasheets, no Allwinner SoC with EPHY has any
extra xtal input pins for the EPHY, and the system xtal is 24MHz.
That means the EPHY is not possible to get a 25MHz xtal input, and thus
the frequency can only be 24MHz.
It doesn't matter on H3 as the default value of H3 is 24MHz, however on
V3s the default value is wrongly set to 25MHz, which prevented the EPHY
from working properly.
Force the EPHY clock frequency to 24MHz.

Add the beginnings of a testsuite for tc functionality in the kernel.
These are a series of unit tests that use the tc executable and verify
the success of those commands by checking both the exit codes and the
output from tc's 'show' operation.
To run the tests:
# cd tools/testing/selftests/tc-testing
# sudo ./tdc.py
You can specify the tc executable to use with the -p argument on the command
line or editing the 'TC' variable in tdc_config.py. Refer to the README for
full details on how to run.
The initial complement of test cases are limited mostly to tc actions. Test
cases are most welcome; see the creating-testcases subdirectory for help
in creating them.

Since commit 217f69743681 ("net: busy-poll: allow preemption in
sk_busy_loop()") there is an explicit do_softirq() invocation after
local_bh_enable() has been invoked.
I don't understand why we need this because local_bh_enable() will
invoke do_softirq() once the softirq counter reached zero and we have
softirq-related work pending.

We should avoid marking goto rules unresolved when their
target is actually reachable after rule deletion.
Consolder following sample scenario:
# ip -4 ru sh
0: from all lookup local
32000: from all goto 32100
32100: from all lookup main
32100: from all lookup default
32766: from all lookup main
32767: from all lookup default
# ip -4 ru del pref 32100 table main
# ip -4 ru sh
0: from all lookup local
32000: from all goto 32100 [unresolved]
32100: from all lookup default
32766: from all lookup main
32767: from all lookup default
After removal of first rule with preference 32100 we
mark all goto rules as unreachable, even when rule with
same preference as removed one still present.
Check if next rule with same preference is available
and make all rules with goto action pointing to it.

====================
qed*: RDMA and infrastructure for iWARP
This series focuses on RDMA in general with emphasis on required changes
toward adding iWARP support. The vast majority of the changes introduced
are in qed/qede, with a couple of small changes to qedr
[mentioned below].
The infrastructure changes:
- Patch #1 adds the ability to pass PBL memory externally for a newly
created chain.
- Patches #4, #5 rename qede_roce.[ch] into qede_rdma.[ch] + change
prefixes from _roce_ to _rdma_, as the API between qede and qedr is
agnostic to the variant of the RDMA protocol used. These patches also
touch qedr [basically to align it with the renaming, nothing more].
- Patch #7 replaces the current SPQ async mechanism into serving
registered callbacks [before adding iWARP which would add another client
in need of this sort of functionallity].
The non-infrastrucutre changes:
- Patches #2, #3 contain DCB-related changes to better align RDMA with
configured DCB.
- Patch #6 contains a minor [mostly theoretical fix] to release flow.
Changes from previous versions
------------------------------
- V4: This is actually a repost of V3 due to some confusion regarding
the sent cover-letter
- V3: Add commit log message in #4 indicating change in header inclusion
- V2: Add several inclusion into qede_rdma.h to have proper declarations
of all variable types used in it

Whenever firmware indicates that there's an async indication it needs
to handle, there's a switch-case where the right functionality is called
based on function's personality and information.
Before iWARP is added [as yet another client], switch over the SPQ into
a callback-registered mechanism, allowing registration of the relevant
event-processing logic based on the function's personality. This allows
us to tidy the code by removing protocol-specifics from a common file.

Once we have iWARP support, the qede portion of the qedr<->qede would
serve all the RDMA protocols - so rename the file to be appropriate

.h files and adding includes to make sure it contains all type

When using sparse on the arm64 tree we get many thousands of
warnings like 'constant ... is so big it is unsigned long long'
or 'shift too big (32) for type unsigned long'. This happens
because by default sparse considers the machine as 32bit and
defines the size of the types accordingly.
Fix this by passing the '-m64' flag to sparse so that
sparse can correctly define longs as being 64bit.

While trying to reduce util.[ch] I noticed that fetch_kernel_version()
and fetch_ubuntu_kernel_version() do lots of operations only to check if
they are needed, i.e. it checks if the pointer where to return the
kernel version is NULL only after obtaining the kernel version from
/proc/version_signature or by parsing the results from uname().
Do it earlier not to confuse people reading this code in the future :-)

Enable gpio support for CP and AP on the Marvell Armada 7K/8K SoCs.
The Armada 8K has two CP110 blocks, each having two GPIO controllers.
However, in each CP110 block, one of the GPIO controller cannot be
used: in the master CP110, only the second GPIO controller can be used,
while on the slave CP110, only the first GPIO controller can be used.
On the other side, the Armada 7K has only one CP110, but both its GPIO
controllers can be used.
For this reason, the GPIO controllers are marked as "disabled" in the
armada-cp110-master.dtsi and armada-cp110-slave.dtsi files, and only
enabled in the per-SoC dtsi files.

'struct video_event' is used for the VIDEO_GET_EVENT ioctl, implemented
by drivers/media/pci/ivtv/ivtv-ioctl.c and
drivers/media/pci/ttpci/av7110_av.c. The structure contains a 'time_t',
which will be redefined in the future to be 64-bit wide, causing an
incompatible ABI change for this ioctl.
As it turns out, neither of the drivers currently sets the timestamp
field, and it is presumably useless anyway because of the limited
resolutions (no sub-second times). This means we can simply change
the structure definition to use a 'long' instead of 'time_t' and
remain compatible with all existing user space binaries when time_t
gets changed.
If anybody ever starts using this field, they have to make sure not
to use 1970 based seconds in there, as those overflow in 2038.
