7846f58fba x86/boot: Fix boot regression caused by bootparam sanitizing
commit a90118c445 ("x86/boot: Save fields explicitly, zero out everything
else") had two errors:

    * It preserved boot_params.acpi_rsdp_addr, and
    * It failed to preserve boot_params.hdr

Therefore, zero out acpi_rsdp_addr, and preserve hdr.

mlxsw: Add devlink-trap support

This patchset adds devlink-trap support in mlxsw.

Patches #1-#4 add the necessary APIs and defines in mlxsw.

Patch #5 implements devlink-trap support for layer 2 drops. More drops
will be added in the future.

Patches #6-#7 add selftests to make sure that all the new code paths are
exercised and that the feature is working as expected.

specific to a single trap, but do not check the devlink-trap common

6a44bae3b2 mlxsw: reg: Add new trap actions
Subsequent patches will add discard traps support in mlxsw. The driver
cannot configure such traps with a normal trap action, but needs to use
exception trap action, which also increments an error counter.

On the other hand, when these traps are initialized or set to drop
action, they should use the default drop action set by the firmware.
This guarantees that when the feature is disabled we get the exact same
behavior as before the feature was introduced.

Probing lower rates can already hurt throughput quite a bit. What hurts even
more is the fact that on mt76x0/mt76x2, single probing packets can only be
forced by directing packets at a different internal hardware queue, which
causes some heavy reordering and extra latency.
The reordering issue is mainly problematic while pushing lots of packets to
a particular station. If there is little activity, the overhead of probing is
neglegible.

The static fallback behavior is designed to pretty much only handle rate
control algorithms that use only a very limited set of rates on which the
algorithm switches up/down based on packet error rate.

In order to better support that kind of hardware, this patch implements a
different approach to rate probing where it switches to a slightly higher rate,
waits for tx status feedback, then updates the stats and switches back to
the new max throughput rate. This only triggers above a packet rate of 100
per stats interval (~50ms).
For that kind of probing, the code has to reduce the set of probing rates
a lot more compared to single packet probing, so it uses only one packet
per MCS group which is either slightly faster, or as close as possible to
the max throughput rate.
This allows switching between similar rates with different numbers of
streams. The algorithm assumes that the hardware will work its way lower
within an MCS group in case of retransmissions, so that lower rates don't
have to be probed by the high packets per second rate probing code.

To further reduce the search space, it also does not probe rates with lower
channel bandwidth than the max throughput rate.

At the moment, these changes will only affect mt76x0/mt76x2.

f793c7eedd mac80211: minstrel_ht: reduce unnecessary rate probing attempts
On hardware with static fallback tables (e.g. mt76x2), rate probing attempts
can be very expensive.
On such devices, avoid sampling rates slower than the per-group max throughput
rate, based on the assumption that the fallback table will take care of probing
lower rates within that group if the higher rates fail.

To further reduce unnecessary probing attempts, skip duplicate attempts on
rates slower than the max throughput rate.

2a38075cd0 nl80211: Add support for EDMG channels
802.11ay specification defines Enhanced Directional Multi-Gigabit
(EDMG) STA and AP which allow channel bonding of 2 channels and more.

Introduce new NL attributes that are needed for enabling and
configuring EDMG support.

Two new attributes are used by kernel to publish driver's EDMG
capabilities to the userspace:
NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16
GHz channel(s) that are supported by the driver.
When this attribute is not set it means driver does not support EDMG.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth
configurations supported by the driver.

Additional two new attributes are used by the userspace for connect
command and for AP configuration:
NL80211_ATTR_WIPHY_EDMG_CHANNELS
NL80211_ATTR_WIPHY_EDMG_BW_CONFIG

New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver
and used for bitrate calculation that will take into account EDMG
according to the 802.11ay specification.

3b5be16c7e modules: page-align module section allocations only for arches supporting strict module rwx
We should keep the case of "#define debug_align(X) (X)" for all arches
without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who
are sensitive to system size, a lot of memory when using modules,
especially for embedded systems. This is also the intention of the
original #ifdef... statement and still valid for now.

Note that this still keeps the effect of the fix of the following commit,
38f054d549 ("modules: always page-align module section allocations"),
since when CONFIG_ARCH_HAS_STRICT_MODULE_RWX is enabled, module pages are
aligned.

0d31d4dbf3 Revert "cfg80211: fix processing world regdomain when non modular"
This reverts commit 96cce12ff6 ("cfg80211: fix processing world
regdomain when non modular").

Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.

This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
  - checks if previous was set by CORE -> yes
    - checks if regulator domain changed -> yes, from '00' to e.g. 'US'
      -> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
  the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
  is not processed yet, so it tries to process it again.
  __reg_process_hint driver() will run again, and:
  - checks if the last request's initiator was the core -> no, it was
    the driver (1st WiFi module)
  - checks, if the previous initiator was the driver -> yes
    - checks if the regulator domain changed -> yes, it was '00' (set by
      core, and crda call did not return yet), and should be changed to 'US'

------> __reg_process_hint_driver calls an intersect

Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.
