The highlight is a largish series to fix nested posted interrupt detection.
The series hasn't gotten any reviews, so if you have time to take a closer look,
it would be appreciated.

The following changes since commit 02b0d3b9d4dd1ef76b3e8c63175f1ae9ff392313:

  KVM: x86: WARN if a vCPU gets a valid wakeup that KVM can't yet inject (2024-06-28 08:59:07 -0700)

----------------------------------------------------------------
KVM VMX changes for 6.11

 - Remove an unnecessary EPT TLB flush when enabling hardware.

 - Fix a series of bugs that cause KVM to fail to detect nested pending posted
   interrupts as valid wake eents for a vCPU executing HLT in L2 (with
   HLT-exiting disable by L1).

 - Misc cleanups
