...
- #GP when trying to set reserved bits of CR4_HI in 64-bit mode
- #GP when trying to set reserved bits of EFER MSR
- clear upper part of RSI/RDI when executing rep instructions with 32-bit asize
even if no repeat iterations were executed (because of RCX=0 for example)
- write SYSENTER_EIP_MSR and SYSENTER_ESP_MSR as 64-bit when x86_64 supported
- set MSR_FMASK reset value
- MSR_FMASK should be 32-bit only
- check for fetch permissions when doing ITLB lookup
- #GP when trying to write non-canonical address to MSR_CSTAR or MSR_LSTAR
- correct repeat instructions timing
- mark TSS busy in TR after it is loaded
