KVM VMX changes for 6.14:

Browse source 
- Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit
    while L2 is active, while ultimately results in a hardware-accelerated L1
    EOI effectively being lost.
 
  - Honor event priority when emulating Posted Interrupt delivery during nested
    VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the
    interrupt.
 
  - Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache
    prior to every VM-Enter.
 
  - Rework KVM's processing of the Page-Modification Logging buffer to reap
    entries in the same order they were created, i.e. to mark gfns dirty in the
    same order that hardware marked the page/PTE dirty.
 
  - Misc cleanups.
