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

08f958f458 Fixed pageWriteStampTable to handle BIOS code as well - increased the table to all 4G instead of allocated memory size 
Avoid checking of pageWriteStamp in the heart of cpu loop with trace cache - now decWriteStamp will post stopTraceExecution event if it hits code page

56dd9fe3d9 - fixed several MSVC compilation warnings 
* MSVC doesn't support localized variables (e.g. valid inside of a 'for' loop
    only). So we cannot use the variable 'i' with different types (unsigned / int)
    in the reset() method.
  * added some conversions from Bit64s to bx_bool

082eb05b6b First step to fully configurable CPUID 
- put CPUID functions data into array, in future we could load this array from configure file
 - cpuid initialize function is more flexible now but still reuire some work

071c5c1a26 A lot of changes but everything is really trivial. 
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
