Intercepting MOV to/from CR3 when using EPT

[Jim Mattson <jmattson@xxxxxxxxxx>]

When using EPT, why does kvm intercept MOV to/from CR3 when paging is
disabled in the guest? It doesn't seem necessary to me, but perhaps I
am missing something.

I'm referring to this code in ept_update_paging_mode_cr0():

exec_controls_setbit(vmx, CPU_BASED_CR3_LOAD_EXITING |
CPU_BASED_CR3_STORE_EXITING);

Thanks!
