a9637ab93c zloop: fix zone append check in zloop_rw()
While commit cf28f6f923 ("zloop: fail zone append operations that are
targeting full zones") added a check in zloop_rw() that a zone append is
not issued to a full zone, commit e3a96ca904 ("zloop: simplify checks
for writes to sequential zones") inadvertently removed the check to
verify that there is enough unwritten space in a zone for an incoming
zone append opration.

Re-add this check in zloop_rw() to make sure we do not write beyond the
end of a zone. Of note is that this same check is already present in the
function zloop_set_zone_append_sector() when ordered zone append is in
use.

c200892b46 ima: Access decompressed kernel module to verify appended signature
Currently, when in-kernel module decompression (CONFIG_MODULE_DECOMPRESS)
is enabled, IMA has no way to verify the appended module signature as it
can't decompress the module.

Define a new kernel_read_file_id enumerate READING_MODULE_COMPRESSED so
IMA can calculate the compressed kernel module data hash on
READING_MODULE_COMPRESSED and defer appraising/measuring it until on
READING_MODULE when the module has been decompressed.

Before enabling in-kernel module decompression, a kernel module in
initramfs can still be loaded with ima_policy=secure_boot. So adjust the
kernel module rule in secure_boot policy to allow either an IMA
signature OR an appended signature i.e. to use
"appraise func=MODULE_CHECK appraise_type=imasig|modsig".

While this does require some "clocks" to be specified in devicetree to
work correctly, thanks to ".qos_requires_clocks = true," this is
backwards compatible with old DT as QoS programming will be skipped for
aggre1_noc and aggre2_noc when clocks are not provided.

fs: move mntput_no_expire() slowpath into a dedicated routine
In the stock variant the compiler spills several registers on the stack
and employs stack smashing protection, adding even more code + a branch
on exit..

The actual fast path is small enough that the compiler inlines it for
all callers -- the symbol is no longer emitted.

Forcing noinline on it just for code-measurement purposes shows the fast
path dropping from 111 to 39 bytes.

7649412af3 KVM: x86: Load guest/host PKRU outside of the fastpath run loop
Move KVM's swapping of PKRU outside of the fastpath loop, as there is no
KVM code anywhere in the fastpath that accesses guest/userspace memory,
i.e. that can consume protection keys.

As documented by commit 1be0e61c1f ("KVM, pkeys: save/restore PKRU when
guest/host switches"), KVM just needs to ensure the host's PKRU is loaded
when KVM (or the kernel at-large) may access userspace memory.  And at the
time of commit 1be0e61c1f, KVM didn't have a fastpath, and PKU was
strictly contained to VMX, i.e. there was no reason to swap PKRU outside
of vmx_vcpu_run().

Over time, the "need" to swap PKRU close to VM-Enter was likely falsely
solidified by the association with XFEATUREs in commit 37486135d3
("KVM: x86: Fix pkru save/restore when guest CR4.PKE=0, move it to x86.c"),
and XFEATURE swapping was in turn moved close to VM-Enter/VM-Exit as a
KVM hack-a-fix ution for an #MC handler bug by commit 1811d979c7
("x86/kvm: move kvm_load/put_guest_xcr0 into atomic context").

Deferring the PKRU loads shaves ~40 cycles off the fastpath for Intel,
and ~60 cycles for AMD.  E.g. using INVD in KVM-Unit-Test's vmexit.c,
with extra hacks to enable CR4.PKE and PKRU=(-1u & ~0x3), latency numbers
for AMD Turin go from ~1560 => ~1500, and for Intel Emerald Rapids, go
from ~810 => ~770.

75c69c82f2 KVM: x86: Load guest/host XCR0 and XSS outside of the fastpath run loop
Move KVM's swapping of XFEATURE masks, i.e. XCR0 and XSS, out of the
fastpath loop now that the guts of the #MC handler runs in task context,
i.e. won't invoke schedule() with preemption disabled and clobber state
(or crash the kernel) due to trying to context switch XSTATE with a mix
of host and guest state.

For all intents and purposes, this reverts commit 1811d979c7 ("x86/kvm:
move kvm_load/put_guest_xcr0 into atomic context"), which papered over an
egregious bug/flaw in the #MC handler where it would do schedule() even
though IRQs are disabled.  E.g. the call stack from the commit:

  kvm_load_guest_xcr0
  ...
  kvm_x86_ops->run(vcpu)
    vmx_vcpu_run
      vmx_complete_atomic_exit
        kvm_machine_check
          do_machine_check
            do_memory_failure
              memory_failure
                lock_page

Commit 1811d979c7 "fixed" the immediate issue of XRSTORS exploding, but
completely ignored that scheduling out a vCPU task while IRQs and
preemption is wildly broken.  Thankfully, commit 5567d11c21 ("x86/mce:
Send #MC singal from task work") (somewhat incidentally?) fixed that flaw
by pushing the meat of the work to the user-return path, i.e. to task
context.

KVM has also hardened itself against #MC goofs by moving #MC forwarding to
kvm_x86_ops.handle_exit_irqoff(), i.e. out of the fastpath.  While that's
by no means a robust fix, restoring as much state as possible before
handling the #MC will hopefully provide some measure of protection in the
event that #MC handling goes off the rails again.

Note, KVM always intercepts XCR0 writes for vCPUs without protected state,
e.g. there's no risk of consuming a stale XCR0 when determining if a PKRU
update is needed; kvm_load_host_xfeatures() only reads, and never writes,
vcpu->arch.xcr0.

Deferring the XCR0 and XSS loads shaves ~300 cycles off the fastpath for
Intel, and ~500 cycles for AMD.  E.g. using INVD in KVM-Unit-Test's
vmexit.c, which an extra hack to enable CR4.OXSAVE, latency numbers for
AMD Turin go from ~2000 => 1500, and for Intel Emerald Rapids, go from
~1300 => ~1000.

63669bd1d5 KVM: VMX: Handle #MCs on VM-Enter/TD-Enter outside of the fastpath
Handle Machine Checks (#MC) that happen on VM-Enter (VMX or TDX) outside
of KVM's fastpath so that as much host state as possible is re-loaded
before invoking the kernel's #MC handler.  The only requirement is that
KVM invokes the #MC handler before enabling IRQs (and even that could
_probably_ be related to handling #MCs before enabling preemption).

Waiting to handle #MCs until "more" host state is loaded hardens KVM
against flaws in the #MC handler, which has historically been quite
brittle. E.g. prior to commit 5567d11c21 ("x86/mce: Send #MC singal from
task work"), the #MC code could trigger a schedule() with IRQs and
preemption disabled.  That led to a KVM hack-a-fix in commit 1811d979c7
("x86/kvm: move kvm_load/put_guest_xcr0 into atomic context").

Note, vmx_handle_exit_irqoff() is common to VMX and TDX guests.

d2932a59c2 ACPI: APEI: EINJ: Fix EINJV2 initialization and injection
ACPI 6.6 specification for EINJV2 appends an extra structure to
the end of the existing struct set_error_type_with_address.

Several issues showed up in testing.

 1) Initialization was broken by an earlier fix [1] since is_v2 is only
    set while performing an injection, not during initialization.

 2) A buggy BIOS provided invalid "revision" and "length" for the
    extension structure. Add several sanity checks.

 3) When injecting legacy error types on an EINJV2 capable system,
    don't copy the component arrays.

1a7fad2aea drm/i915/cx0: Enable dpll framework for MTL+
MTL+ platforms are supported by dpll framework remove a separate
check for hw comparison and rely solely on dpll framework
hw comparison.

Finally, all required hooks are now in place so initialize
PLL manager for MTL+ platforms and remove the redirections
to the legacy code paths from the following interfaces:

* intel_encoder::clock_enable/disable()
* intel_encoder::get_config()
* intel_dpll_funcs::get_hw_state()
* intel_ddi_update_active_dpll()
* pipe_config_pll_mismatch()

v2: Rebase on !HAS_LT_PHY check in intel_ddi_update_active_dpll()
v3: Rebase on !display->dpll.mgr check in intel_ddi_update_active_dpll()
    Add check for NVL as the platform is not part of pll framework (Suraj)

2a6e417907 drm/i915/cx0: Add MTL+ Thunderbolt PLL hooks
Add the PLL hooks for the TBT PLL on MTL+. These are simple stubs
similarly to the TBT PLL on earlier platforms, since this PLL is always
on from the display POV - so no PLL enable/disable programming is
required as opposed to the non-TBT PLLs - and the clocks for different
link rates are enabled/disabled at a different level, via the
intel_encoder::enable_clock()/disable_clock() interface.
