I've been wondering still about omap2-mcspi related suspend and resume
flakeyness and looks like we're missing calls to spi_master_suspend()
and spi_master_resume(). Adding those and using pm_runtime_force_suspend()
and pm_runtime_force_resume() makes things work for suspend and resume
and allows us to stop using noirq suspend and resume.
And while at it, let's use SET_SYSTEM_SLEEP_PM_OPS to simplify things
further.

When re-registering a user mr, the mpt information for the
existing mr when running SRIOV is obtained via the QUERY_MPT
fw command. The returned information includes the mpt's lkey.
This retrieved mpt information is used to move the mpt back
to hardware ownership in the rereg flow (via the SW2HW_MPT
fw command when running SRIOV).
The fw API spec states that for SW2HW_MPT, the lkey field
must be zero. Any ConnectX-3 PF driver which checks for strict spec
adherence will return failure for SW2HW_MPT if the lkey field is not
zero (although the fw in practice ignores this field for SW2HW_MPT).
Thus, in order to conform to the fw API spec, set the lkey field to zero
before invoking SW2HW_MPT when running SRIOV.

Jan improves the code readability in XDP by adding the use of a local

VF's via locking mechanism to prevent unstable behaviour and potential
kernel panics.
Krzysztof adds a hardware capability flag to indicate whether firmware
supports stopping the LLDP agent.
Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer
is NULL terminated.
Mitch fixes the issue of trying to start nway on devices that do not
support auto-negotiation, by checking the autoneg state before
attempting to restart nway.

[Why]
Many panels support more than 8bpc but some modes are unavailable while
running at greater than 8bpc due to DP/HDMI bandwidth constraints.
Support for more than 8bpc was added recently in the driver but it
defaults to the maximum supported bpc - locking out these modes.
This should be a user configurable option such that the user can select
what bpc configuration they would like.
[How]
This patch adds support for getting and setting the amdgpu driver
specific "max bpc" property on the connector.
It also adds support for limiting the output bpc based on the property
value. The default limitation is the lowest value in the range, 8bpc.
This was the old value before the range was uncapped.
This patch should be updated/replaced later once common drm support
for max bpc lands.

mlxsw: spectrum: acl: Introduce ERP sharing by multiple masks
Jiri says:
The Spectrum-2 hardware has limitation number of ERPs per-region. In
order to accommodate more masks than number of ERPs, the hardware
supports to insert rules with delta bits. By that, the rules with masks
that differ in up-to 8 consecutive bits can share the same ERP.
Patches 1 and 2 fix couple of issues that would appear in existing
selftests after adding delta support
Patch 3 introduces a generic object aggregation library. Now it is
static, but it will get extended for recalculation of aggregations in
the future in order to reach more optimal aggregation.
Patch 4 just simply converts existing ERP code to use the objagg library
instead of a rhashtable.
Patches 5-9 do more or less small changes to prepare ground for the last
patch.
Patch 10 fills-up delta callbacks of objagg library and utilizes the
delta bits for rule insertion.
The last patch adds selftest to test the mlxsw Spectrum-2 delta flows.

composed from a logical OR between all the unmasked bits in the region.
Currently, this is just a logical OR between all the eRPs used in the
region, but the next patch is going to introduce delta bits support
which need to be taken into account as well.

When the firmware starts, it doesn't have any regulatory
information, hence it uses the world wide limitations. The
driver can feed the firmware with previous knowledge that
was kept in the driver, but the firmware may still not
update its internal tables.
This happens when we start a BSS interface, and then the
firmware can change the regulatory tables based on our
location and it'll use more lenient, location specific
rules. Then, if the firmware is shut down (when the
interface is brought down), and then an AP interface is
created, the firmware will forget the country specific
rules.
The host will think that we are in a certain country that
may allow channels and will try to teach the firmware about
our location, but the firmware may still not allow to drop
the world wide limitations and apply country specific rules
because it was just re-started.
In this case, the firmware will reply with MCC_RESP_ILLEGAL
to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let
the upper layers (cfg80211 / hostapd) know that the channel
list they know about has been updated.

The current condition makes it difficult to compile the amlogic/
drivers with COMPILE_TEST, or without ARCH_MESON in general.
Fixes kbuild errors with patch series that depend on drivers in that
directory, for instance the meson video decoder.

This was introduced with v2.6.27 commit 287ac01acf ("[SCSI] zfcp: Cleanup
code in zfcp_erp.c") but would now suppress helpful -Wswitch compiler
warnings when building with W=1 such as the following forced example:
drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_setup_act':
drivers/s390/scsi/zfcp_erp.c:220:2: warning: enumeration value 'ZFCP_ERP_ACTION_REOPEN_PORT' not handled in switch [-Wswitch]
switch (need) {
^~~~~~
But then again, only with W=1 we would notice unhandled enum cases.
Without the default cases and a missed unhandled enum case, the code might
perform unforeseen things we might not want...
As of today, we never run through the removed default case, so removing it
is no functional change. In the future, we never should run through a
default case but introduce the necessary specific case(s) to handle new
functionality.

For some reason the already existing substring "fall through" in the
comment is not sufficient for GCC to silence -Wimplicit-fallthrough.

Improve whatever the following simple invocation reported:

While at it, improve some related kdoc,
including struct zfcp_fsf_ct_els in zfcp_fsf.h.

With that instead of just "int" it becomes clear which functions return
this type and which ones also accept it as argument they just pass through
in some cases or modify in other cases. v2.6.27 commit 287ac01acf
("[SCSI] zfcp: Cleanup code in zfcp_erp.c") introduced the enum which was
cpp defines previously.
Silence some false -Wswitch compiler warning cases with individual
NOP cases. When adding more enum values and building with W=1 we
would get compiler warnings about missed new cases.
Consistently use the variable name "result", so change "retval" in
zfcp_erp_strategy() to "result". This avoids confusion with other compile
unit variables "retval" having different semantics and type.

Use the already defined enum for this purpose to get at least some build
checking (even though an enum is type equivalent to an int in C). v2.6.27
commit 287ac01acf ("[SCSI] zfcp: Cleanup code in zfcp_erp.c") introduced
the enum which was cpp defines previously.
Since struct zfcp_erp_action type is embedded into other structures living
in zfcp_def.h, we have to move enum zfcp_erp_act_type from its private
definition in zfcp_erp.c to the zfcp-global zfcp_def.h
Silence some false -Wswitch compiler warning cases with individual NOP
cases. When adding more enum values and building with W=1 we would get
compiler warnings about missed new cases.
Add missing break statements in some of the above switch cases. No
functional change, but making it future-proof. I think all of these should
have had a break statement ever since, even if these switch cases happened
to be the last ones in the switch statement body.
"Fall through" in the context of switch case usually means not to have a
break and fall through to the subsequent switch case. However, I think this
old comment meant that here we do not have an _early return_ in the switch
case but the code path continues after the switch case body.
