  KVM: x86: avoid underflow when scaling TSC frequency (2025-07-09 13:52:50 -0400)

Many patches, pretty much all of them small, that accumulated while I
was on vacation.
----------------------------------------------------------------
ARM:

- Remove the last leftovers of the ill-fated FPSIMD host state
  mapping at EL2 stage-1

- Fix unexpected advertisement to the guest of unimplemented S2 base
  granule sizes

- Gracefully fail initialising pKVM if the interrupt controller isn't
  GICv3

- Also gracefully fail initialising pKVM if the carveout allocation
  fails

- Fix the computing of the minimum MMIO range required for the host on
  stage-2 fault

- Fix the generation of the GICv3 Maintenance Interrupt in nested mode

x86:

- Reject SEV{-ES} intra-host migration if one or more vCPUs are actively
  being created, so as not to create a non-SEV{-ES} vCPU in an SEV{-ES} VM.

- Use a pre-allocated, per-vCPU buffer for handling de-sparsification of
  vCPU masks in Hyper-V hypercalls; fixes a "stack frame too large" issue.

- Allow out-of-range/invalid Xen event channel ports when configuring IRQ
  routing, to avoid dictating a specific ioctl() ordering to userspace.

- Conditionally reschedule when setting memory attributes to avoid soft
  lockups when userspace converts huge swaths of memory to/from private.

- Add back MWAIT as a required feature for the MONITOR/MWAIT selftest.

- Add a missing field in struct sev_data_snp_launch_start that resulted in
  the guest-visible workarounds field being filled at the wrong offset.

- Skip non-canonical address when processing Hyper-V PV TLB flushes to avoid
  VM-Fail on INVVPID.

- Advertise supported TDX TDVMCALLs to userspace.

- Pass SetupEventNotifyInterrupt arguments to userspace.

- Fix TSC frequency underflow.
