Merge cpufreq updates for 6.15-rc1:
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code from drivers (Viresh Kumar).
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, and zuoqian).
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai).
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski).
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng).
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar).
- Make it possible to avoid enabling capacity-aware scheduling (CAS) in
the intel_pstate driver and relocate a check for out-of-band (OOB)
platform handling in it to make it detect OOB before checking HWP
availability (Rafael Wysocki).
- Fix dbs_update() to avoid inadvertent conversions of negative integer
values to unsigned int which causes CPU frequency selection to be
inaccurate in some cases when the "conservative" cpufreq governor is
in use (Jie Zhan).

and SM8650
Add SDX75 and SA8775p compatibles to respective if:then: blocks to
narrow their properties and add a new section for SM8650 with four 'reg'
and 'interrupts' (top-level already allows four).
SA8755p DTS comes without interrupts, but only because they might not
be available for OS under given firmware.

interrupt-names
When narrowing properties per variant, the 'interrupt-names' should have
the same constraints as 'interrupts'. Add missing upper bound on the
property.

for_each_possible_cpu() is currently used to initialize cpufreq.
However, in cpu_dev_register_generic(), for_each_present_cpu()
is used to register CPU devices which means the CPU devices are
only registered for present CPUs and not all possible CPUs.
With nosmp or maxcpus=0, only the boot CPU is present, lead
to the cpufreq probe failure or defer probe due to no cpu device
available for not present CPUs.
Change for_each_possible_cpu() to for_each_present_cpu() in the
above cpufreq drivers to ensure it only registers cpufreq for
CPUs that are actually present.

Physical address space is 48 bit on Loongson-3A5000 physical machine,
however it is 47 bit for VM on Loongson-3A5000 system. Size of physical
address space of VM is the same with the size of virtual user space (a
half) of physical machine.
Variable cpu_vabits represents user address space, kernel address space
is not included (user space and kernel space are both a half of total).
Here cpu_vabits, rather than cpu_vabits - 1, is to represent the size of
guest physical address space.
Also there is strict checking about page fault GPA address, inject error
if it is larger than maximum GPA address of VM.

On host, the HW guest CSR registers are lost after suspend and resume
operation. Since last_vcpu of boot CPU still records latest vCPU pointer
so that the guest CSR register skips to reload when boot CPU resumes and
vCPU is scheduled.
Here last_vcpu is cleared so that guest CSR registers will reload from
scheduled vCPU context after suspend and resume.

The problem is that base address allocated from hugetlbfs is not aligned
with pmd size. Here add a checking for hugetlbfs and align base address
with pmd size. After this patch the test case "testcases/bin/hugefork02"
passes to run.
This is similar to the commit 7f24cbc9c4d42db8a3c8484d1 ("mm/mmap: teach
generic_get_unmapped_area{_topdown} to handle hugetlb mappings").

When CONFIG_RANDOM_KMALLOC_CACHES or other randomization infrastructrue
enabled, the idle_task's stack may different between the booting kernel
and target kernel. So when resuming from hibernation, an ACTION_BOOT_CPU
IPI wakeup the idle instruction in arch_cpu_idle_dead() and jump to the
interrupt handler. But since the stack pointer is changed, the interrupt
handler cannot restore correct context.
So rename the current arch_cpu_idle_dead() to idle_play_dead(), make it
as the default version of play_dead(), and the new arch_cpu_idle_dead()
call play_dead() directly. For hibernation, implement an arch-specific
hibernate_resume_nonboot_cpu_disable() to use the polling version (idle
instruction is replace by nop, and irq is disabled) of play_dead(), i.e.
poll_play_dead(), to avoid IPI handler corrupting the idle_task's stack
when resuming from hibernation.
This solution is a little similar to commit 406f992e4a372dafbe3c ("x86 /
hibernate: Use hlt_play_dead() when resuming from hibernation").

Compared to the SNP Guest Request, the "Extended" version adds data pages for
receiving certificates. If not enough pages provided, the HV can report to the
VM how much is needed so the VM can reallocate and repeat.
Commit
ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex")
moved handling of the allocated/desired pages number out of scope of said
mutex and create a possibility for a race (multiple instances trying to
trigger Extended request in a VM) as there is just one instance of
snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex.
Fix the issue by moving the data blob/size and the GHCB input struct
(snp_req_data) into snp_guest_req which is allocated on stack now and accessed
by the GHCB caller under that mutex.
Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four
callers needs it. Free the received blob in get_ext_report() right after it is
copied to the userspace. Possible future users of snp_send_guest_request() are
likely to have different ideas about the buffer size anyways.

ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex")
narrowed the command mutex scope to snp_send_guest_request(). However,
GET_REPORT, GET_DERIVED_KEY, and GET_EXT_REPORT share the req structure in
snp_guest_dev. Without the mutex protection, concurrent requests can overwrite
each other's data. Fix it by dynamically allocating the request structure.

The fix to atomically read the pipe head and tail state when not holding
the pipe mutex has caused a number of headaches due to the size change
of the involved types.
It turns out that we don't have _that_ many places that access these
fields directly and were affected, but we have more than we strictly
should have, because our low-level helper functions have been designed
to have intimate knowledge of how the pipes work.
And as a result, that random noise of direct 'pipe->head' and
'pipe->tail' accesses makes it harder to pinpoint any actual potential
problem spots remaining.
For example, we didn't have a "is the pipe full" helper function, but
instead had a "given these pipe buffer indexes and this pipe size, is
the pipe full". That's because some low-level pipe code does actually
want that much more complicated interface.
But most other places literally just want a "is the pipe full" helper,
and not having it meant that those places ended up being unnecessarily
much too aware of this all.
It would have been much better if only the very core pipe code that
cared had been the one aware of this all.
So let's fix it - better late than never. This just introduces the
trivial wrappers for "is this pipe full or empty" and to get how many
pipe buffers are used, so that instead of writing
if (pipe_full(pipe->head, pipe->tail, pipe->max_usage))
the places that literally just want to know if a pipe is full can just
say
if (pipe_is_full(pipe))
instead. The existing trivial cases were converted with a 'sed' script.
This cuts down on the places that access pipe->head and pipe->tail
directly outside of the pipe code (and core splice code) quite a lot.
The splice code in particular still revels in doing the direct low-level
accesses, and the fuse fuse_dev_splice_write() code also seems a bit
unnecessarily eager to go very low-level, but it's at least a bit better
than it used to be.
