  KVM: VMX: Add array_index_nospec() to evmcs_field_offset() (2026-11-02 13:15:45 -0500)

----------------------------------------------------------------
x86:

- Check validity of vmcb01 save area copied from SMRAM on RSM

- Conditionally resched when retrying gPTE walk on A/D update failure

- Conditionally resched when restarting REP string emulation

- Process each host MSR entry at most once when unwinding failed VM-Entry

- Cap number of parents of page table pages, to avoid quadratic teardown

- Unconditionally reset MMU context when emulating INIT

- Flush guest TLB when emulating a RESET to strictly honor the spec

- Add array_index_nospec() to evmcs_field_offset()
