379708ffde mm: add the first tail page to struct folio
Some of the static checkers get confused by extracting the page from the
folio and referring to fields in the first tail page.  Adding these fields
to struct folio lets us avoid doing that.  It has the risk that people
will refer to those fields without checking that the folio is actually a
large folio, so prefix them with underscores and document the preferred
function to use instead.

79e1119b7e ksm: remove redundant declarations in ksm.h
Currently, for struct stable_node, no one uses it in both the
include/linux/ksm.h file and the file that contains it.  For struct
mem_cgroup, it's also not used in ksm.h.  So they're all redundant, just
remove them.

b76c14c8fb drm/i915/huc: better define HuC status getparam possible return values.
The current HuC status getparam return values are a bit confusing in
regards to what happens in some scenarios. In particular, most of the
error cases cause the ioctl to return an error, but a couple of them,
INIT_FAIL and LOAD_FAIL, are not explicitly handled and neither is
their expected return value documented; these 2 error cases therefore
end up into the catch-all umbrella of the "HuC not loaded" case, with
this case therefore including both some error scenarios and the load
in progress one.

The updates included in this patch change the handling so that all
error cases behave the same way, i.e. return an errno code, and so
that the HuC load in progress case is unambiguous.

The patch also includes a small change to the FW init path to make sure
we always transition to an error state if something goes wrong.

Add mei bus API for sending gsc commands: mei_cldev_send_gsc_command()

The GSC commands are originated in the graphics stack
and are in form of SGL DMA buffers.
The GSC commands are synchronous, the response is received
in the same call on the out sg list buffers.
The function setups pointers for in and out sg lists in the
mei sgl extended header and sends it to the firmware.

86a4d29e75 ASoC: Updates for v6.1
This has been a very quiet release for the core but quite a busy one for
 drivers with a big crop of new drivers and lots of feature additions and
 fixes to existing ones:
 
  - A new string helper parse_int_array_user().
  - Improvements to the SOF IPC4 code, especially around trace.
  - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon
    systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek
    MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450
    and Texas Instruments SRC4392
 
 There is a conflict with the conversion of I2C remove functions to void
 in the cs42l42 driver which is fairly straightforward to resolve but
 should be highlighted to Linus.

ASoC: Updates for v6.1

This has been a very quiet release for the core but quite a busy one for
drivers with a big crop of new drivers and lots of feature additions and
fixes to existing ones:

 - A new string helper parse_int_array_user().
 - Improvements to the SOF IPC4 code, especially around trace.
 - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon
   systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek
   MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450
   and Texas Instruments SRC4392

There is a conflict with the conversion of I2C remove functions to void
in the cs42l42 driver which is fairly straightforward to resolve but
should be highlighted to Linus.

62c07983be once: add DO_ONCE_SLOW() for sleepable contexts
Christophe Leroy reported a ~80ms latency spike
happening at first TCP connect() time.

This is because __inet_hash_connect() uses get_random_once()
to populate a perturbation table which became quite big
after commit 4c2c8f03a5 ("tcp: increase source port perturb table to 2^16")

get_random_once() uses DO_ONCE(), which block hard irqs for the duration
of the operation.

This patch adds DO_ONCE_SLOW() which uses a mutex instead of a spinlock
for operations where we prefer to stay in process context.

Then __inet_hash_connect() can use get_random_slow_once()
to populate its perturbation table.

Fixes: 4c2c8f03a5 ("tcp: increase source port perturb table to 2^16")
Fixes: 190cc82489 ("tcp: change source port randomizarion at connect() time")

09bbedac72 net: phy: mdio-i2c: support I2C MDIO protocol for RollBall SFP modules
Some multigig SFPs from RollBall and Hilink do not expose functional
MDIO access to the internal PHY of the SFP via I2C address 0x56
(although there seems to be read-only clause 22 access on this address).

Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced
Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be
selected to 3 and the password must be filled with 0xff bytes for this
PHY communication to work.

This extends the mdio-i2c driver to support this protocol by adding a
special parameter to mdio_i2c_alloc function via which this RollBall
protocol can be selected.

Instead of configuring the I2C mdiobus when SFP driver is probed,
create/destroy the mdiobus before the PHY is probed for/after it is
released.

This way we can tell the mdio-i2c code which protocol to use for each
SFP transceiver.

Move the code that determines MDIO I2C protocol from
sfp_sm_probe_for_phy() to sfp_sm_mod_probe(), where most of the SFP ID
parsing is done. Don't allocate I2C bus if no PHY is expected.

eca68a3c7d net: phylink: pass supported host PHY interface modes to phylib for SFP's PHYs
Pass the supported PHY interface types to phylib if the PHY we are
connecting is inside a SFP, so that the PHY driver can select an
appropriate host configuration mode for their interface according to
the host capabilities.

For example the Marvell 88X3310 PHY inside RollBall SFP modules
defaults to 10gbase-r mode on host's side, and the marvell10g
driver currently does not change this setting. But a host may not
support 10gbase-r. For example Turris Omnia only supports sgmii,
1000base-x and 2500base-x modes. The PHY can be configured to use
those modes, but in order for the PHY driver to do that, it needs
to know which modes are supported.

fd580c9830 net: sfp: augment SFP parsing with phy_interface_t bitmap
We currently parse the SFP EEPROM to a bitmap of ethtool link modes,
and then attempt to convert the link modes to a PHY interface mode.
While this works at present, there are cases where this is sub-optimal.
For example, where a module can operate with several different PHY
interface modes.

To start addressing this, arrange for the SFP EEPROM parsing to also
provide a bitmap of the possible PHY interface modes.

Moving an iterator of the macros inside conditional part of for-loop
helps to generate a better code. It had been first implemented in commit
7baac8b91f ("cpumask: make for_each_cpu_mask a bit smaller").

Now that cpumask for-loops are the aliases to bitmap loops, it's worth
to optimize them the same way.

The difference between for_each_cpu() and for_each_set_bit()
is that the latter uses cpumask_next() instead of find_next_bit(),
and so calls cpumask_check().

This check is useless because the iterator value is not provided by

ae3bbc04d4 net: devlink: add port_init/fini() helpers to allow pre-register/post-unregister functions
Lifetime of some of the devlink objects, like regions, is currently
forced to be different for devlink instance and devlink port instance
(per-port regions). The reason is that for devlink ports, the internal
structures initialization happens only after devlink_port_register() is
called.

To resolve this inconsistency, introduce new set of helpers to allow
driver to initialize devlink pointer and region list before
devlink_register() is called. That allows port regions to be created
before devlink port registration and destroyed after devlink
port unregistration.

d20a6ba5e3 kunit: add kunit.enable to enable/disable KUnit test
This patch adds the kunit.enable module parameter that will need to be
set to true in addition to KUNIT being enabled for KUnit tests to run.
The default value is true giving backwards compatibility. However, for
the production+testing use case the new config option
KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in
by passing kunit.enable=1 to the kernel.
