Pull x86 TDX updates from Dave Hansen:
"The only real thing of note here is printing the TDX module version.
This is a little silly on its own, but the upcoming TDX module update
code needs the same TDX module call. This shrinks that set a wee bit.
There's also few minor macro cleanups and a tweak to the GetQuote ABI
to make it easier for userspace to detect zero-length (failed) quotes"

Pull x86 mm updates from Dave Hansen:
- Convert x86 code to use generic "pagetable" APIs and ptdescs
This aligns some the set_memory*() code better with the new page
table APIs, especially using ptdescs as opposed to 'struct page'
directly.

Jason A. Donenfeld says:
====================
WireGuard fixes for 7.1-rc1
1) Asbjørn's YNL sample, finally merged. Sorry for the wait on this one.
2) A simplification to use kfree_rcu instead of call_rcu, since
kfree_rcu now works with kmem caches.
3) A trivial formatting derp.
4) Fix for a deadlock by moving to using exit_rtnl instead of pre_exit.

pre_exit
wg_netns_pre_exit() manually acquires rtnl_lock() inside the
pernet .pre_exit callback. This causes a hung task when another
thread holds rtnl_mutex - the cleanup_net workqueue (or the
setup_net failure rollback path) blocks indefinitely in
wg_netns_pre_exit() waiting to acquire the lock.
Convert to .exit_rtnl, introduced in commit 7a60d91c690b ("net:
Add ->exit_rtnl() hook to struct pernet_operations."), where the
framework already holds RTNL and batches all callbacks under a
single rtnl_lock()/rtnl_unlock() pair, eliminating the contention
window.
The rcu_assign_pointer(wg->creating_net, NULL) is safe to move
from .pre_exit to .exit_rtnl (which runs after synchronize_rcu())
because all RCU readers of creating_net either use maybe_get_net()
- which returns NULL for a dying namespace with zero refcount - or
access net->user_ns which remains valid throughout the entire
ops_undo_list sequence.

Pull timer core updates from Thomas Gleixner:
- A rework of the hrtimer subsystem to reduce the overhead for
frequently armed timers, especially the hrtick scheduler timer:
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing
a RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which
both can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the
need resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where
the scheduler has picked the next task and has the next hrtick
timer armed. In case that there is no immediate reschedule or
soft interrupts have to be handled before reaching the reschedule
point in the interrupt entry code the clock event is reprogrammed
in one of those code paths to prevent that the timer becomes
stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other
hrtimer users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the
hrtimer and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design,
which was made in the context of systems far smaller than today, is
based on the assumption that the to be monitored clocksource (TSC)
can be trivially compared against a known to be stable clocksource
(HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to
the boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other
CPUs based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

The HP OMEN MAX 16-ak0xxx (8D87) requires the same WMI queries as other
Victus S devices, hence it has been added to the corresponding list.
For this reason, platform_profile_victus_s_get_ec() will be called
during thermal_profile_setup() and victus_s_powersource_event() to
obtain hardware state (platform profile) by reading from the Embedded
Controller, however, this particular board's EC does not seem to expose
the platform profile value, unlike other boards. Hence EC readback is
disabled.

For Victus S devices, the BIOS fan table header was being incorrectly
parsed as:
struct {
u8 unknown;
u8 num_entries;
}
The first field should be num_fans and the second should be unknown. It
is pure coincidence that interpreting an "unknown" field as "num_entries"
worked on multiple device, however for board 8D87 (in an upcoming patch),
this assumption fails, and the hp-wmi driver fails to load.
We fix this by correcting the header definition and compensating for
num_entries by parsing each entry of the fan table until an all-NULL row
is obtained, mirroring the behavior of OMEN Gaming Hub on Windows.

The RSI interface can return RSI_INCOMPLETE when a report spans
multiple granules. This is an expected condition and should not be
treated as a fatal error.
Currently, arm_cca_report_new() checks for `info.result != RSI_SUCCESS`
and bails out, which incorrectly flags RSI_INCOMPLETE as a failure.
Fix the check to only break out on results other than RSI_SUCCESS or
RSI_INCOMPLETE.
This ensures partial reports are handled correctly and avoids spurious

- Remove multiple ksft_run()s to fix the recently enforced hard-fail
- Move all the setup inside the test cases for the ones under
selftests/net/ (I'll defer the HW ones to David)
- Add more test coverage related to queue leasing behavior and corner
cases, so now we have 45 tests in nk_qlease.py with netdevsim
which does not need special HW

Add further netkit queue-lease coverage for netns lifecycle of the guest
and physical halves, channel resize across active leases, single-device
and multi-lessee scenarios, L3 mode operation, lease capacity exhaustion,
and corner-cases of e.g. queue-create rejection paths. Also make the tests
more robust by removing the time.sleep(0.1) after netns deletion and turn
them into a wait loop.

As pointed out in 3d2c3d2eea9a ("selftests: net: py: explicitly forbid
multiple ksft_run() calls"), ksft_run() cannot be called multiple times.
Move the netdevsim-based queue lease tests to selftests/net/ so that
each file has exactly one ksft_run() call.
The HW tests (io_uring ZC RX, queue attrs, XDP with MP, destroy) remain
in selftests/drivers/net/hw/.

YnlFamily opens an AF_NETLINK socket in __init__ but has no way
to release it other than leaving it to the GC. YnlFamily holds a
self reference cycle through SpecFamily's self.family = self
in its super().__init__() call, so refcount GC cannot reclaim
it and the socket stays open until the cyclic GC runs.
If a test creates a guest netns, instantiates a YnlFamily inside
it via NetNSEnter(), performs some test case work via Ynl, and
then deletes the netns, then the 'ip netns del' only drops the
mount binding and cleanup_net in the kernel never runs, so any
subsequent test case assertions that objects got cleaned up would
fail given this only gets triggered later via cyclic GC run.
Add an explicit close() that closes the netlink socket and wire
up the __enter__/__exit__ so callers can scope the instance
deterministically via 'with YnlFamily(...) as ynl: ...'.
