892fa99c6f - 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

2aaafa76a2 Reorganize fetchdecode tables with another level of redirection - a leap toward future improvements 
Currently no speedup and no slowdown - about the same results on my Bochs benchmarking
A lot of code reorganization in fetchdecode

08f958f458 Fixed pageWriteStampTable to handle BIOS code as well - increased the table to all 4G instead of allocated memory size
