- prefetch hint should be NOP when use in register mode
...
- #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

Fixed required to make MSVC build with fastcall optimization (-Gr) healthy.
...
There is a trick in MSVC is to turn on the -Gr compiler switch which tells MSVC to compile all functions using fastcall calling convention. This way you don't have to edit each function declaration. But certain functions must NOT be fastcall, and those are callbacks from Windows which are defined either as cdecl or stdcall. The entry point main() also has to remain cdecl.
