PM / OPP: Add reference counting helpers for Rust implementation

OPP: add index check to assert to avoid buffer overflow in _read_freq()

To ensure that resources such as OPP tables or OPP nodes are not freed
while in use by the Rust implementation, it is necessary to increment
their reference count from Rust code.
This commit introduces a new helper function,
dev_pm_opp_get_opp_table_ref(), to increment the reference count of an
OPP table and declares the existing helper dev_pm_opp_get() in pm_opp.h.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

Commit 3c55e94c0a ("cpufreq: ACPI: Extend frequency tables to cover
boost frequencies") introduced an assumption in acpi_cpufreq_cpu_init()
that the first entry in the P-state table was the nominal frequency.
This assumption is incorrect. The frequency corresponding to the P0
P-State need not be the same as the nominal frequency advertised via
CPPC.
Since the driver is using the CPPC.highest_perf and CPPC.nominal_perf
to compute the boost-ratio, it makes sense to use CPPC.nominal_freq to
compute the max-frequency. CPPC.nominal_freq is advertised on
platforms supporting CPPC revisions 3 or higher.
Hence, fallback to using the first entry in the P-State table only on
platforms that do not advertise CPPC.nominal_freq.

Here are some small staging driver fixes that resolve some reported

They resolve the following issues:
- lots of gpib build-time fixes as reported by testers and 0-day
- gpib logical fixes
- mailmap fix (already in your tree, but git merge should handle it.)
All of these have been in linux-next for a while, with no reported

- Align set_id_regs selftest with the fact that ASIDBITS field is RO
- Various vPMU fixes for bugs that only affect nested virt
The new __kvm_faultin_pfn() function is upset by the fact that e500
KVM ignores host page permissions - __kvm_faultin requires a "writable"
outgoing argument, but e500 KVM is passing NULL.
While a simple fix would be possible that simply allows writable to
be NULL, it is quite ugly to have e500 KVM ignore completely the host
permissions and map readonly host pages as guest-writable. Merge a more
complete fix and remove the VMA-based attempts at building huge shadow TLB
entries. Using a PTE lookup, similar to what is done for x86, is better
and works with remap_pfn_range() because it does not assume that VM_PFNMAP
areas are contiguous. Note that the same incorrect logic is there in
ARM's get_vma_page_shift() and RISC-V's kvm_riscv_gstage_ioremap().
Fortunately, for e500 most of the code is already there; it just has to
be changed to compute the range from find_linux_pte()'s output rather
than find_vma(). The new code works for both VM_PFNMAP and hugetlb
mappings, so the latter is removed.
Patches 2-5 were tested by the reporter, Christian Zigotzky. Since
the difference with v1 is minimal, I am going to send it to Linus
today.
e500 KVM tries to bypass __kvm_faultin_pfn() in order to map VM_PFNMAP
VMAs as huge pages. This is a Bad Idea because VM_PFNMAP VMAs could
become noncontiguous as a result of callsto remap_pfn_range().
Instead, use the already existing host PTE lookup to retrieve a
valid host-side mapping level after __kvm_faultin_pfn() has
returned. Then find the largest size that will satisfy the
guest's request while staying within a single host PTE.

The new __kvm_faultin_pfn() function is upset by the fact that e500 KVM
ignores host page permissions - __kvm_faultin requires a "writable"
outgoing argument, but e500 KVM is nonchalantly passing NULL.
If the host page permissions do not include writability, the shadow
TLB entry is forcibly mapped read-only.

Add the possibility of marking a page so that the UW and SW bits are
force-cleared. This is stored in the private info so that it persists
across multiple calls to kvmppc_e500_setup_stlbe.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
kvmppc_e500_ref_setup is returning whether the guest TLB entry is writable,
which is than passed to kvm_release_faultin_page. This makes little sense
for two reasons: first, because the function sets up the private data for
the page and the return value feels like it has been bolted on the side;
second, because what really matters is whether the _shadow_ TLB entry is
writable. If it is not writable, the page can be released as non-dirty.
Shift from using tlbe_is_writable(gtlbe) to doing the same check on
the shadow TLB entry.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
If find_linux_pte fails, IRQs will not be restored. This is unlikely
to happen in practice since it would have been reported as hanging
hosts, but it should of course be fixed anyway.

Pull io_uring fixes from Jens Axboe:
- Fix for multishot timeout updates only using the updated value for
the first invocation, not subsequent ones
- Silence a false positive lockdep warning
- Fix the eventfd signaling and putting RCU logic
- Fix fault injected SQPOLL setup not clearing the task pointer in the
error path
- Fix local task_work looking at the SQPOLL thread rather than just
signaling the safe variant. Again one of those theoretical issues,
which should be closed up none the less.

Over the Christmas break, a couple of devicetree fixes came in
for Rockchips, Qualcomm and NXP/i.MX. These add some missing
board specific properties, address build time warnings,
The USB/TOG supoprt on X1 Elite regressed, so two earlier DT
changes get reverted for now.
Aside from the devicetree fixes, there is One build fix for the
stm32 firewall driver, and a defconfig change to enable SPDIF
support for i.MX.

Maddy is taking over the day-to-day maintenance of powerpc. I will still
be around to help, and as a backup.
Re-order the main POWERPC list to put Maddy first to reflect that.
KVM/powerpc patches will be handled by Maddy via the powerpc tree with
review from Nick, so replace myself with Maddy there.
Remove myself from BPF, leaving Hari & Christophe as maintainers.

In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

- Fix corner case bug where ops.dispatch() couldn't extend the execution of
the current task if SCX_OPS_ENQ_LAST is set.
- Fix ops.cpu_release() not being called when a SCX task is preempted by a
higher priority sched class task.
- Fix buitin idle mask being incorrectly left as busy after an idle CPU is
picked and kicked.
- scx_ops_bypass() was unnecessarily using rq_lock() which comes with rq
pinning related sanity checks which could trigger spuriously. Switch to
raw_spin_rq_lock().
