This WA is applicable to BMG as well.
Note that this is a GSC WA and we don't load the GSC on BMG, so
extending the WA to BMG won't do anything right now. However, it helps
future-proof the driver so that if we ever turn the GSC on we won't have
to remember to extend this WA.

Thomas Gleixner says:
====================
ptp: Provide support for auxiliary clocks for PTP_SYS_OFFSET_EXTENDED
This is a follow up to the V1 series, which can be found here:
https://lore.kernel.org/all/20250626124327.667087805@linutronix.de
to address the merge logistics problem, which I created myself.
Changes vs. V1:
- Make patch 1, which provides the timestamping function temporarily
define CLOCK_AUX* if undefined so that it can be merged independently,
- Add a missing check for CONFIG_POSIX_AUX_CLOCK in the PTP IOCTL
- Picked up tags
Merge logistics if agreed on:
1) Patch #1 is applied to the tip tree on top of plain v6.16-rc1 and
tagged
2) That tag is merged into tip:timers/ptp and the temporary CLOCK_AUX
define is removed in a subsequent commit
3) Network folks merge the tag and apply patches #2 + #3
So the only fallout from this are the extra merges in both trees and the
cleanup commit in the tip tree. But that way there are no dependencies and
no duplicate commits with different SHAs.
Thoughts?
Due to the above constraints there is no branch offered to pull from right
now. Sorry for the inconveniance. Should have thought about that earlier.

Allow ioctl(PTP_SYS_OFFSET_EXTENDED*) to select CLOCK_AUX clock ids for
generating the pre and post hardware readout timestamps.
Aside of adding these clocks to the clock ID validation, this also requires
to check the timestamp to be valid, i.e. the seconds value being greater
than or equal zero. This is necessary because AUX clocks can be
asynchronously enabled or disabled, so there is no way to validate the
availability upfront.
The same could have been achieved by handing the return value of
ktime_get_aux_ts64() all the way down to the IOCTL call site, but that'd
require to modify all existing ptp::gettimex64() callbacks and their inner
call chains. The timestamp check achieves the same with less churn and less
complicated code all over the place.

The inlined ptp_read_system_[pre|post]ts() switch cases expand to a copious
amount of text in drivers, e.g. ~500 bytes in e1000e. Adding auxiliary
clock support to the inlines would increase it further.
Replace the inline switch case with a call to ktime_get_clock_ts64(), which
reduces the code size in drivers and allows to access auxiliary clocks once
they are enabled in the IOCTL parameter filter.
No functional change.

tray is used for both SD and SIM cards. If the SD card is placed
at the outermost location in the tray, the SIM card may come in
contact with SD card power-supply while removing the tray, possibly
resulting in SIM damage.
To prevent that, make sure the SD card is really inserted by reading
the Card Detect pin state. If it's not, turn off the power in
sdhci_msm_check_power_status() and also set the BUS_FAIL power state
on the controller as part of pwr_irq handling for BUS_ON request.

The timer which ensures that no more than 3 LACPDUs are transmitted in
a second rearms itself every 333ms regardless of whether an LACPDU is
transmitted when the timer expires. This causes LACPDU tx to be delayed
until the next expiration of the timer, which effectively aligns LACPDUs
to ~333ms boundaries. This results in a variable amount of jitter in the
timing of periodic LACPDUs.
Change this to only rearm the timer when an LACPDU is actually sent,
allowing tx at any point after the timer has expired.

PTP implements an inline switch case for taking timestamps from various
POSIX clock IDs, which already consumes quite some text space. Expanding it
for auxiliary clocks really becomes too big for inlining.
Provide a out of line version.
The function invalidates the timestamp in case the clock is invalid. The
invalidation allows to implement a validation check without the need to
propagate a return value through deep existing call chains.
Due to merge logistics this temporarily defines CLOCK_AUX[_LAST] if
undefined, so that the plain branch, which does not contain any of the core
timekeeper changes, can be pulled into the networking tree as prerequisite
for the PTP side changes. These temporary defines are removed after that
branch is merged into the tip::timers/ptp branch. That way the result in
-next or upstream in the next merge window has zero dependencies.

The DCCP socket family has now been removed from this tree, see:
8bb3212be4 ("Merge branch 'net-retire-dccp-socket'")
Remove connection tracking and NAT support for this protocol, this
should not pose a problem because no DCCP traffic is expected to be seen
on the wire.
As for the code for matching on dccp header for iptables and nftables,
mark it as deprecated and keep it in place. Ruleset restoration is an
atomic operation. Without dccp matching support, an astray match on dccp
could break this operation leaving your computer with no policy in
place, so let's follow a more conservative approach for matches.
Add CONFIG_NFT_EXTHDR_DCCP which is set to 'n' by default to deprecate
dccp extension support. Similarly, label CONFIG_NETFILTER_XT_MATCH_DCCP
as deprecated too and also set it to 'n' by default.
Code to match on DCCP protocol from ebtables also remains in place, this
is just a few checks on IPPROTO_DCCP from _check() path which is
exercised when ruleset is loaded. There is another use of IPPROTO_DCCP
from the _check() path in the iptables multiport match. Another check
for IPPROTO_DCCP from the packet in the reject target is also removed.
So let's schedule removal of the dccp matching for a second stage, this
should not interfer with the dccp retirement since this is only matching
on the dccp header.

Revert commit 234f715550 ("ACPI: battery: negate current when

of battery monitoring: Steam and MangoHud. Perhaps it breaks more,
but those are the two that have been tested.

This patch describes the two MMC controllers of the Loongson-2K2000 SoC,
one providing an eMMC interface and the other exporting an SD/SDIO
interface.
Compared to the Loongson-2K1000's MMC controllers, their internals are
similar, except that we use an internally exclusive DMA engine instead of
an externally shared APBDMA engine.

The MMC controllers on the Loongson-2K series CPUs are similar,
except for the interface characteristics and the use of DMA controllers.
This patch describes the MMC controllers on the Loongson-2K0500/2K1000,
with the distinguishing feature being the use of an externally shared
APBDMA engine.

Not all tasks have an ABI associated or vDSO mapped,
for example kthreads never do.
If such a task ever ends up calling stack_top(), it will derefence the
NULL ABI pointer and crash.
This can for example happen when using kunit:
mips_stack_top+0x28/0xc0
arch_pick_mmap_layout+0x190/0x220
kunit_vm_mmap_init+0xf8/0x138
__kunit_add_resource+0x40/0xa8
kunit_vm_mmap+0x88/0xd8
usercopy_test_init+0xb8/0x240
kunit_try_run_case+0x5c/0x1a8
kunit_generic_run_threadfn_adapter+0x28/0x50
kthread+0x118/0x240
ret_from_kernel_thread+0x14/0x1c
Only dereference the ABI point if it is set.
The GIC page is also included as it is specific to the vDSO.
Also move the randomization adjustment into the same conditional.

Add SDHI bindings for the Renesas RZ/T2H (a.k.a R9A09G077) and RZ/N2H
(a.k.a R9A09G087) SoCs. Use `renesas,sdhi-r9a09g057` as a fallback since
the SD/MMC block on these SoCs is identical to the one on RZ/V2H(P),
allowing reuse of the existing driver without modifications.
Update the binding schema to reflect differences: unlike RZ/V2H(P),
RZ/T2H and RZ/N2H do not require the `resets` property and use only a
two clocks instead of four.

regset even if there is no register data supplied, causing the tests for
setting vector lengths and setting SVE_VL_INHERIT in sve-ptrace to
spuriously fail. Set the flag to avoid the issue, we still support not
supplying register data.
