  Merge tag 'kvm-riscv-fixes-7.2-1' of https://github.com/kvm-riscv/linux into HEAD (2026-07-21 12:25:45 +0200)

----------------------------------------------------------------
RISC-V:

- Avoid redundant allocations when allocating IMSIC page tables

- Apply SBI FWFT LOCK flag only on successful set

- Bound SBI PMU counter mask scan to BITS_PER_LONG, since on RV32
  the PMU SBI start/stop helper can only access 32 PMU counters.

- Skip TLB flush when G-stage PTE becomes valid if the Svvptc
  extension is available.

- Always show Zicbo[m|z|p] block sizes in ONE_REG

- Inject instruction access fault on unmapped guest fetch

- Use raw spinlock for irqs_pending and irqs_pending_mask

- Fix Spectre-v1 in vector register access via ONE_REG

x86:

- Fixes to SEV selftests.

- Once free_nested() did a VMCLEAR of shadow VMCS, there's no need to VMCLEAR it
  again if the kernel is preempted and thread migration happens

- Preserve nested TDP shadow page tables if they are used as roots, instead of
  clearing them unnecessarily

- Fix use of stale data if out-of-memory happens after vendor module reload

- Check for invalid/obsolete root *after* making MMU pages available, because
  the latter can make a page invalid

- Only reset TSC Deadline Timer in apic_timer_expired on KVM_RUN
