The MAC address of a port is 6 octets in size, and this creates a 2

that we can put in that hole. One such member is the stp_state.

Nomap regions are treated as "reserved". When region boundaries are not
page aligned, we usually increase the "reserved" regions rather than
decrease them. So, we should use memblock_region_reserved_base_pfn()/
memblock_region_reserved_end_pfn() instead of memblock_region_memory_
base_pfn()/memblock_region_memory_base_pfn() to calculate boundaries.

Legion Y9000X 2020 has a speaker, but the speaker doesn't work.
This can be fixed by applying alc285_fixup_ideapad_s740_coef
to fix the speaker's coefficients.
Besides, to support the transition between the speaker and the headphone,
alc287_fixup_legion_15imhg05_speakers needs to be run.

net: hns3: refactor rss/tqp stats functions
Currently, hns3 PF and VF module have two sets of rss and tqp stats APIs
to provide get and set functions. Most of these APIs are the same. There is
no need to keep these two sets of same functions for double development and
bugfix work.
This series refactor the rss and tqp stats APIs in hns3 PF and VF by
implementing one set of common APIs for PF and VF reuse and deleting the
old APIs.

Currently PF and VF use two sets of command code for modules to interact
with firmware. These codes values are same espect the macro names. It is
redundent to keep two sets of command code for same functions between PF
and VF.
So this patch firstly creates a unified command code for PF and VF module.
We keep the macro name same with the PF command code name to avoid too many
meaningless modifications. Secondly the new common command codes are used
to replace the old ones in VF and deletes the old ones.

In the case a device can support retaining the firmware memory across
low power states it is useful for the preloader widget to only power up
whilst actually loading/unloading the core, as opposed to the normal
operation where the widget is powered for the entire time a firmware is
preloaded onto the core. Add support for this mode and a flag to enable
it.

If the Halo registers are kept in the register cache the
HALO_CORE_RESET bit will be retained as 1 after reset is triggered in
cs_dsp_halo_start_core. This will cause subsequent writes to reset
the core which is not desired. Apart from this bit the rest of the
register bits are cacheable, so for safety sake clear the bit to
ensure the cache is consistent.

It makes no sense to cache the test/user key registers, since they
require values written at specific times, mark them volatile. It is
probably best if they can't be accessed from user-space either, so
mark them precious as well.
The interrupt force, edge, polarity and debounce are all settings
applied to the IRQ rather than status bits and as such should not be
volatile.
The OTP trim values will require re-application in the event of a
cache sync and as such should not be volatile. The OTPID however
should be volatile.
The DSP scratch registers are used to read back an error/debug code
from the DSP on shutdown, as such these should be marked volatile.
Finally, add some missing defaults, add TST_FS_MON0, and allow the
DSP core control register to be cached.

The tc_redirect umounts /sys in the new namespace, which can be
mounted as shared and cause global umount. The lazy umount also
takes down mounted trees under /sys like debugfs, which won't be
available after sysfs mounts again and could cause fails in other
tests.
# cat /proc/self/mountinfo | grep debugfs

Making the sysfs private under the new namespace so the umount won't

This patch introduces new probes to check whether the kernel supports
instruction set extensions v2 and v3. The first introduced eBPF
instructions BPF_J{LT,LE,SLT,SLE} in commit 92b31a9af73b ("bpf: add
BPF_J{LT,LE,SLT,SLE} instructions"). The second introduces 32-bit
variants of all jump instructions in commit 092ed0968bb6 ("bpf:
verifier support JMP32").
These probes are useful for userspace BPF projects that want to use newer
instruction set extensions on newer kernels, to reduce the programs'
sizes or their complexity. LLVM already provides an mcpu=probe option to
automatically probe the kernel and select the newest-supported
instruction set extension. That is however not flexible enough for all
use cases. For example, in Cilium, we only want to use the v3
instruction set extension on v5.10+, even though it is supported on all
kernels v5.1+.

There is currently a single miscellaneous feature probe,
HAVE_LARGE_INSN_LIMIT, to check for the 1M instructions limit in the
verifier. Subsequent patches will add additional miscellaneous probes,
which follow the same pattern at the existing probe. This patch
therefore refactors the probe to avoid code duplication in subsequent
patches.
The BPF program type and the checked error numbers in the
HAVE_LARGE_INSN_LIMIT probe are changed to better generalize to other
probes. The feature probe retains its current behavior despite those
changes.

As started by commit 05a5f51ca566 ("Documentation: Replace lkml.org links
with lore"), an effort was made to replace lkml.org links with lore to
better use a single source that's more likely to stay available long-term.
However, it seems these links don't offer much value here, so just
remove them entirely.

net: lan966x: Extend switchdev with mdb support
This patch series extends lan966x with mdb support by implementing
the switchdev callbacks: SWITCHDEV_OBJ_ID_PORT_MDB and
SWITCHDEV_OBJ_ID_HOST_MDB.
It adds support for both ipv4/ipv6 entries and l2 entries.
v2->v3:
- rename PGID_FIRST and PGID_LAST to PGID_GP_START and PGID_GP_END
- don't forget and relearn an entry for the CPU if there are more
references to the cpu.
v1->v2:
- rename lan966x_mac_learn_impl to __lan966x_mac_learn
- rename lan966x_mac_cpu_copy to lan966x_mac_ip_learn
- fix grammar and typos in comments and commit messages
- add reference counter for entries that copy frames to CPU

Extend lan966x driver with mdb support by implementing the switchdev
calls: SWITCHDEV_OBJ_ID_PORT_MDB and SWITCHDEV_OBJ_ID_HOST_MDB.
It is allowed to add both ipv4/ipv6 entries and l2 entries. To add
ipv4/ipv6 entries is not required to use the PGID table while for l2
entries it is required. The PGID table is much smaller than MAC table
so only fewer l2 entries can be added.

The first entries in the PGID table are used by the front ports while
the last entries are used for different purposes like flooding mask,
copy to CPU, etc. So add these macros to define which entries can be
used for general purpose.

Extend mac functionality with the function lan966x_mac_ip_learn. This
function adds an entry in the MAC table for IP multicast addresses.
These entries can copy a frame to the CPU but also can forward on the
front ports.
This functionality is needed for mdb support. In case the CPU and some
of the front ports subscribe to an IP multicast address.

====================
net: ethernet: mtk_eth_soc: refactoring and Clause 45
Rework value and type of mdio read and write functions in mtk_eth_soc
and generally clean up and unify both functions.
Then add support to access Clause 45 phy registers, using newly
introduced helper inline functions added by a patch Russell King has
suggested in a reply to an earlier version of this series [1].
All three commits are tested on the Bananapi BPi-R64 board having
MediaTek MT7531BE DSA gigE switch using clause 22 MDIO and
Ubiquiti UniFi 6 LR access point having Aquantia AQR112C PHY using
clause 45 MDIO.
[1]: https://lore.kernel.org/netdev/Ycr5Cna76eg2B0An@shell.armlinux.org.uk/
v11: also address return value of mtk_mdio_busy_wait
v10: correct order of SoB lines in 2/3, change patch order in series
v9: improved formatting and Cc missing maintainer
v8: add patch from Russel King, switch to bitfield helper macros
v7: remove unneeded variables and order OR-ed call parameters
v6: further clean up functions and more cleanly separate patches
v5: fix wrong variable name in first patch covered by follow-up patch
v4: clean-up return values and types, split into two commits
v3: return -1 instead of 0xffff on error in _mtk_mdio_write
v2: use MII_DEVADDR_C45_SHIFT and MII_REGADDR_C45_MASK to extract
device id and register address. Unify read and write functions to
have identical types and parameter names where possible as we are
anyway already replacing both function bodies.
