Merge tag 'kvm-x86-vmx-6.15' of https://github.com/kvm-x86/linux into HEAD

KVM VMX changes for 6.15

 - Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus
   modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1.

 - Pass XFD_ERR as a psueo-payload when injecting #NM as a preparatory step
   for upcoming FRED virtualization support.

 - Decouple the EPT entry RWX protection bit macros from the EPT Violation bits
   as a general cleanup, and in anticipation of adding support for emulating
   Mode-Based Execution (MBEC).

 - Reject KVM_RUN if userspace manages to gain control and stuff invalid guest
   state while KVM is in the middle of emulating nested VM-Enter.

 - Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs
   in anticipation of adding sanity checks for secondary exit controls (the
   primary field is out of bits).
