Merge a fix for a race condition related to device removal (Bart Van
Assche) for 7.0-rc5.
* pm-runtime:
PM: runtime: Fix a race condition related to device removal
There are two special cases in the idle loop that are handled
inconsistently even though they are analogous.
The first one is when a cpuidle driver is absent and the default CPU
idle time power management implemented by the architecture code is used.
In that case, the scheduler tick is stopped every time before invoking
default_idle_call().
The second one is when a cpuidle driver is present, but there is only
one idle state in its table. In that case, the scheduler tick is never
stopped at all.
Since each of these approaches has its drawbacks, reconcile them with
the help of one simple heuristic. Namely, stop the tick if the CPU has
been woken up by it in the previous iteration of the idle loop, or let
it tick otherwise.

Pull probes fixes from Masami Hiramatsu:
- Avoid crash when rmmod/insmod after ftrace killed
This fixes a kernel crash caused by kprobes on the symbol in a module
which is unloaded after ftrace_kill() is called.
- Remove unneeded warnings from __arm_kprobe_ftrace()
Remove unneeded WARN messages which can be triggered if the kprobe is
using ftrace and it fails to enable the ftrace. Since kprobes
correctly handle such failure, we don't need to warn it.

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.
ARM:
- Correctly handle deactivation of interrupts that were activated
from LRs. Since EOIcount only denotes deactivation of interrupts
that are not present in an LR, start EOIcount deactivation walk
*after* the last irq that made it into an LR
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when pKVM
is already enabled -- not only thhis isn't possible (pKVM will
reject the call), but it is also useless: this can only happen for
a CPU that has already booted once, and the capability will not
change
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was
exposed by the recent conversion to kmalloc_obj(); rip out all the
ugliness that led to the wart
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR
access, float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in
kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked
as available whenever the kernel used scattered feature words for
them
- Validate _all_ GVAs, rather than just the first GVA, when
processing a range of GVAs for Hyper-V's TLB flush hypercalls
- Fix a brown paper bug in add_atomic_switch_msr()
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel
local APIC (and AVIC is enabled at the module level)
- Update CR8 write interception when AVIC is (de)activated, to fix a
bug where the guest can run in perpetuity with the CR8 intercept
enabled
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to
allow L1 hypervisors to set FREEZE_IN_SMM. This reverts (by
default) an unintentional tightening of userspace ABI in 6.17, and
provides some amount of backwards compatibility with hypervisors
who want to freeze PMCs on VM-Entry
- Validate the VMCS/VMCB on return to a nested guest from SMM,
because either userspace or the guest could stash invalid values in
memory and trigger the processor's consistency checks
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from
being unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite
being rather unintuitive
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd
selftest to 64 (from 8)"

Pull Rust fixes from Miguel Ojeda:
"Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint
- Emit dependency information into '$(depfile)' directly to avoid a
temporary '.d' file (it was an old approach)
'kernel' crate:
- 'str' module: fix warning under '!CONFIG_BLOCK' by making
'NullTerminatedFormatter' public
- 'cpufreq' module: suppress false positive Clippy warning
'pin-init' crate:
- Remove '#[disable_initialized_field_access]' attribute which was
unsound. This means removing the support for structs with unaligned
fields (through the 'repr(packed)' attribute), for now
And document the load-bearing fact of field accessors (i.e. that
they are required for soundness)
- Replace shadowed return token by 'unsafe'-to-create token in order
to remain sound in the face of the likely upcoming Type Alias Impl
Trait (TAIT) and the next trait solver in upstream Rust"

snprintf() returns the number of characters that would have been
written excluding the NUL terminator. Output is truncated when the
return value is >= the buffer size, not just > the buffer size.
When ret == size, the current code takes the non-truncated path,
advancing buf by ret and reducing size to 0. This is wrong because
the output was actually truncated (the last character was replaced by
NUL). Fix by using >= so the truncation path is taken correctly.

The bounds check for brace_index happens after the array write.
While the current call pattern prevents an actual out-of-bounds
access (the previous call would have returned an error), the
write-before-check pattern is fragile and would become a real
out-of-bounds write if the error return were ever not propagated.
Move the bounds check before the array write so the function is
self-contained and safe regardless of caller behavior.

__xbc_open_brace() pushes entries with post-increment
(open_brace[brace_index++]), so brace_index always points one past
the last valid entry. xbc_verify_tree() reads open_brace[brace_index]
to report which brace is unclosed, but this is one past the last
pushed entry and contains stale/zero data, causing the error message
to reference the wrong node.
Use open_brace[brace_index - 1] to correctly identify the unclosed
brace. brace_index is known to be > 0 here since we are inside the
if (brace_index) guard.
