bfcbb81602 SVM: 
- IO intercept is not implemented yet
 - MSR intercept is not implemented yet

VMX:
 Fixed Bochs PANIC crash when doing I/O access crossing VMX I/O permission bitmaps.
 This can happen because access_physical_read and access_physical_write cannot access memory cross 4K boundary.

75bda1d5cd implemented SVM emulation support for Bochs (incomplete yet) 
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.

Also looking for anybody with existing SVM kernels - as simple as possible - for testing.

Status:
 - exceptions intercept is not implemented yet
 - IO intercept is not implemented yet
 - MSR intercept is not implemented yet
 - virtual interrupts are not implemented yet
 - CPUID is not implemented yet

No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.

92bb77ef1d Merge patch from SF tracker: 
[3298173] Breakpoint on VMEXIT event by Jianan Hao

Patch description:

The patch provides a new command "vmexitbp" to set breakpoint when VM guest exit. The simulation will be stopped before first HOST mode instruction is executed.

Usage:
Type "vmexitbp" in debugger command window to switch it on/off (similar to modebp).


Currently, the patch has no corresponding interface on GUI debugger. Someone may add it if interested.
