  kvm: retry nx_huge_page_recovery_thread creation (2025-03-01 02:54:18 -0500)

----------------------------------------------------------------
ARM:

* Fix TCR_EL2 configuration to not use the ASID in TTBR1_EL2
  and not mess-up T1SZ/PS by using the HCR_EL2.E2H==0 layout.

* Bring back the VMID allocation to the vcpu_load phase, ensuring
  that we only setup VTTBR_EL2 once on VHE. This cures an ugly
  race that would lead to running with an unallocated VMID.

RISC-V:

* Fix hart status check in SBI HSM extension

* Fix hart suspend_type usage in SBI HSM extension

* Fix error returned by SBI IPI and TIME extensions for
  unsupported function IDs

* Fix suspend_type usage in SBI SUSP extension

* Remove unnecessary vcpu kick after injecting interrupt
  via IMSIC guest file

x86:

* Fix an nVMX bug where KVM fails to detect that, after nested
  VM-Exit, L1 has a pending IRQ (or NMI).

* To avoid freeing the PIC while vCPUs are still around, which
  would cause a NULL pointer access with the previous patch,
  destroy vCPUs before any VM-level destruction.

* Handle failures to create vhost_tasks
