KVM/riscv changes for 6.12

- Fix sbiret init before forwarding to userspace
- Don't zero-out PMU snapshot area before freeing data
- Allow legacy PMU access from guest
- Fix to allow hpmcounter31 from the guest

LoongArch KVM changes for v6.12

1. Revert qspinlock to test-and-set simple lock on VM.
2. Add Loongson Binary Translation extension support.
3. Add PMU support for guest.
4. Enable paravirt feature control from VMM.
5. Implement function kvm_para_has_feature().

KVM/arm64 updates for 6.12

* New features:

  - Add a Stage-2 page table dumper, reusing the main ptdump
    infrastructure, and allowing easier debugging of the our
    page-table infrastructure

  - Add FP8 support to the KVM/arm64 floating point handling.

  - Add NV support for the AT family of instructions, which mostly
    results in adding a page table walker that deals with most of the
    complexity of the architecture.

* Improvements, fixes and cleanups:

  - Add selftest checks for a bunch of timer emulation corner cases

  - Fix the multiple of cases where KVM/arm64 doesn't correctly handle
    the guest trying to use a GICv3 that isn't advertised

  - Remove REG_HIDDEN_USER from the sysreg infrastructure, making
    things little more simple

  - Prevent MTE tags being restored by userspace if we are actively
    logging writes, as that's a recipe for disaster

  - Correct the refcount on a page that is not considered for MTE tag
    copying (such as a device)

  - Relax the synchronisation when walking a page table to split block
    mappings, moving it at the end the walk, as there is no need to
    perform it on every store.

  - Fix boundary check when transfering memory using FFA

  - Fix pKVM TLB invalidation, only affecting currently out of tree
    code but worth addressing for peace of mind

Implement function kvm_para_has_feature() to detect supported paravirt
features. It can be used by device driver to detect and enable paravirt
features, such as the EIOINTC irqchip driver is able to detect feature
KVM_FEATURE_VIRT_EXTIOI and do some optimization.

Export kernel paravirt features to user space, so that VMM can control
each single paravirt feature. By default paravirt features will be the
same with kvm supported features if VMM does not set it.

Also a new feature KVM_FEATURE_VIRT_EXTIOI is added which can be set
from user space. This feature indicates that the virt EIOINTC can route
interrupts to 256 vCPUs, rather than 4 vCPUs like with real HW.

On LoongArch, the host and guest have their own PMU CSRs registers and
they share PMU hardware resources. A set of PMU CSRs consists of a CTRL
register and a CNTR register. We can set which PMU CSRs are used by the
guest by writing to the GCFG register [24:26] bits.

On KVM side:
- Save the host PMU CSRs into structure kvm_context.
- If the host supports the PMU feature.
  - When entering guest mode, save the host PMU CSRs and restore the guest PMU CSRs.
  - When exiting guest mode, save the guest PMU CSRs and restore the host PMU CSRs.

Since SPSR_* are not associated with any register in the sysreg array,

Therefore hidden_user_visibility() serves no purpose here, and can be

We go trough a great deal of effort to map CNTKCTL_EL12 to CNTKCTL_EL1
while hidding this mapping from userspace via a special visibility helper.

However, it would be far simpler to just provide an accessor doing the
mapping job, removing the need for a visibility helper.

With that done, we can also remove the EL12_REG() macro which serves
no purpose.

While arch/*/mem/ptdump handles the kernel pagetable dumping code,
introduce KVM/ptdump to show the guest stage-2 pagetables. The
separation is necessary because most of the definitions from the
stage-2 pagetable reside in the KVM path and we will be invoking
functionality specific to KVM. Introduce the PTDUMP_STAGE2_DEBUGFS config.

When a guest is created, register a new file entry under the guest
debugfs dir which allows userspace to show the contents of the guest
stage-2 pagetables when accessed.

When we share memory through FF-A and the description of the buffers
exceeds the size of the mapped buffer, the fragmentation API is used.
The fragmentation API allows specifying chunks of descriptors in subsequent
FF-A fragment calls and no upper limit has been established for this.
The entire memory region transferred is identified by a handle which can be
used to reclaim the transferred memory.
To be able to reclaim the memory, the description of the buffers has to fit
in the ffa_desc_buf.
Add a bounds check on the FF-A sharing path to prevent the memory reclaim
from failing.

Also do_ffa_mem_xfer() does not need __always_inline, except for the
BUILD_BUG_ON() aspect, which gets moved to a macro.

Pull clk fixes from Stephen Boyd:
 "A pile of Qualcomm clk driver fixes with two main themes: the alpha
  PLL driver and shared RCGs, and one fix for the Starfive JH7110 SoC.

   - The Alpha PLL clk_ops had multiple problems around setting rates.

     There are a handful of patches here that fix masks and skip
     enabling the clk from set_rate() when the PLL is disabled. The PLLs
     are crucial to operation of the system as almost all frequencies in
     the system are derived from them.

   - Parking shared RCGs at a slow always on clk at registration time
     breaks stuff.

     USB host mode can't handle such a slow frequency and the serial
     console gets all garbled when the UART clk is handed over to the
     kernel. There's a few patches that don't use the shared clk_ops for
     the UART clks and another one to skip parking the USB clk at
     registration time.

   - The Starfive PLL driver used for the CPU was busted causing cpufreq
     to fail because the clk didn't change to a safe parent during
     set_rate().

     The fix is to register a notifier and switch to a safe parent so
     the PLL can change rate in a glitch free manner"
