Pull core timer updates from Thomas Gleixner:
"Timers and timekeeping updates:
- A large overhaul of the posix CPU timer code which is a preparation
for moving the CPU timer expiry out into task work so it can be
properly accounted on the task/process.
An update to the bogus permission checks will come later during the
merge window as feedback was not complete before heading of for
travel.
- Switch the timerqueue code to use cached rbtrees and get rid of the
homebrewn caching of the leftmost node.
- Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
single function
- Implement the separation of hrtimers to be forced to expire in hard
interrupt context even when PREEMPT_RT is enabled and mark the
affected timers accordingly.
- Implement a mechanism for hrtimers and the timer wheel to protect
RT against priority inversion and live lock issues when a (hr)timer
which should be canceled is currently executing the callback.
Instead of infinitely spinning, the task which tries to cancel the
timer blocks on a per cpu base expiry lock which is held and
released by the (hr)timer expiry code.
- Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
resulting in faster access to timekeeping functions.
- Updates to various clocksource/clockevent drivers and their device
tree bindings.
- The usual small improvements all over the place"

Pull x86 apic updates from Thomas Gleixner:
- Cleanup the apic IPI implementation by removing duplicated code and
consolidating the functions into the APIC core.
- Implement a safe variant of the IPI broadcast mode. Contrary to
earlier attempts this uses the core tracking of which CPUs have been
brought online at least once so that a broadcast does not end up in
some dead end in BIOS/SMM code when the CPU is still waiting for
init. Once all CPUs have been brought up once, IPI broadcasting is
enabled. Before that regular one by one IPIs are issued.
- Drop the paravirt CR8 related functions as they have no user anymore
- Initialize the APIC TPR to block interrupt 16-31 as they are reserved
for CPU exceptions and should never be raised by any well behaving
device.
- Emit a warning when vector space exhaustion breaks the admin set
affinity of an interrupt.
- Make sure to use the NMI fallback when shutdown via reboot vector IPI
fails. The original code had conditions which prevent the code path
to be reached.
- Annotate various APIC config variables as RO after init.
[ The ipi broadcase change came in earlier through the cpu hotplug
branch, but I left the explanation in the commit message since it was
shared between the two different branches - Linus ]

- Update the interrupt spreading code so it handles numa node with
different CPU counts properly.
- A large overhaul of the ARM GiCv3 driver to support new PPI and SPI

instead of virtual addresses so the virtual addresses are not
leaked. The physical address is sufficient to identify the
associated interrupt chip.

Pull x86 pti updates from Thomas Gleixner:
"Two small PTI updates:
- Handle unaligned addresses gracefully in pti_clone_pagetable(). Not
an issue with current callers, but a correctness problem. Adds a
warning so any caller which hands in an unaligned address gets
pointed out clearly.
- Prevent PTI functions from being invoked when PTI is disabled at
boottime. While this does not cause any harm today, it's pointless
code executed and prone to cause subtle issues if the PTI
implementation changes internally over time"

Pull CPU hotplug updates from Thomas Gleixner:
"A small update for the SMP hotplug code code:
- Track "booted once" CPUs in a cpumask so the x86 APIC code has an
easy way to decide whether broadcast IPIs are safe to use or not.
- Implement a cpumask_or_equal() helper for the IPI broadcast
evaluation.
The above two changes have been also pulled into the x86/apic
branch for implementing the conditional IPI broadcast feature.
- Cache the number of online CPUs instead of reevaluating it over and
over. num_online_cpus() is an unreliable snapshot anyway except
when it is used outside a cpu hotplug locked region. The cached
access is not changing this, but it's definitely faster than
calculating the bitmap wheight especially in hot paths"

it will cause a situation that gce can wait the event immediately
after client ask gce to wait event but not really trigger the

In order to make sure that the wait event function is

so we move the CMDQ_IRQ_MASK into cmdq driver data and calculate
it by thread number.

Writing the 0x1704 (BUS_BAR1_BLOCK) register causes the GPU to probe the
memory region at the programmed address. The result is an address decode
error in the external memory controller because address 0, which is what
is written to the register, is not designated as accessible to devices.
Avoid triggering DMA from the GPU by removing teardown of the BAR1.

When the last reference to a TTM BO is dropped, ttm_bo_release() will
acquire the DMA reservation object's wound/wait mutex while trying to
clean up (ttm_bo_cleanup_refs_or_queue() via ttm_bo_release()). It is
therefore essential that drm_gem_object_release() be called after the
TTM BO has been uninitialized, otherwise drm_gem_object_release() has
already destroyed the wound/wait mutex (via dma_resv_fini()).

Prior to commit 019cbd4a4feb ("drm/nouveau: Initialize GEM object before
TTM object"), the reservation object was locked across all of the buffer
object creation.
After splitting nouveau_bo_new() into separate nouveau_bo_alloc() and
nouveau_bo_init() functions, the reservation object is passed to the
latter, so the lock needs to be held across that function as well.

Commit 019cbd4a4feb ("drm/nouveau: Initialize GEM object before TTM
object") introduced a subtle change in how the buffer allocation size is
handled. Prior to that change, the size would get aligned to at least a
page, whereas after that change a non-page-aligned size would get passed
through unmodified. This ultimately causes a BUG_ON() to trigger in
drm_gem_private_object_init() and crashes the system.
Fix this by restoring the code that align the allocation size.

On the ThinkPad P71, we have one eDP connector exposed along with 5 DP
connectors, resulting in a total of 11 TMDS encoders. Since the GPU on
this system is also capable of MST, we create an additional 4 fake MST
encoders for each DP port. Unfortunately, we also do this for the eDP
port as well, resulting in:
1 eDP port: +1 TMDS encoder
+4 DPMST encoders
5 DP ports: +2 TMDS encoders
+4 DPMST encoders
*5 ports
== 35 encoders
Which breaks things, since DRM has a hard coded limit of 32 encoders.
So, fix this by not creating MSTMs for any eDP connectors. This brings
us down to 31 encoders, although we can do better.
This fixes driver probing for nouveau on the ThinkPad P71.
