62d0c8abf7 - Now you could disable x86-64 from .bochsrc so now it is possible to emulate 
32-bit CPU using Bochs binary compiled with x86-64 support.

The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.

1b9f286945 - New way of CPUs scheduling in SMP mode brings up to 50% speedup to the 
SMP emulation. New implementation uses dynamic CPU quantum value and takes
   full advantage of the trace cache. Each emulated processor will execute
   the whole trace before switching to the next processor.
 * It is also safe to use large (up to 16 instructions) quantum values for
   the SMP emulation now and improve performance even further.

The same merge also completely fixes SF bug :
  [3312237] stepN command might be not working properly

Handlers chaining speedups are also supported with SMP emulation now.

371dc200fc Remove the 'trace' debug feature fro the main stream (which now runs with handlers chaining) and this way reduce each handler size. 
Another 3% speedup on WinXP boot on top of handlers chaining + reduction of Bochs binary size by 45K.

4a3209ae31 Increase cpu param length (exceeded with new icount variable) 
CHECK_MAX_INSTRUCTIONS is not needed for debugger anymore.
Next step: eliminate it for SMP as well and remove cpu_loop parameter.

b69f728246 Fixed internal debugger part of the bug: 
#3312237 stepN command might be not working properly
The problem still can be exists for SMP.

f15bc6cf75 support for NX outside of x86-64. 
required for Intel Yonah processor which is another interesting CPUID to be added
also found Via C7 CPUID, looking for the way to add it too

1d89709e62 Added another CPU to CPUDB: p4_willamette (one more without x86-64 support). 
Reimplemented CPUDB using pure C macros magic.
Fixed compilation errors when compiling with SMP on.

1a051f9f00 Added several predefined CPUs that can be selected from .bochsrc using new CPU::MODEL option. 
Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
	core2_extreme_x9770
	corei7_sandy_bridge_2600K
	p4_prescott_celeron_336

78327d3e5e First step toward completely configurable CPU. 
Change CPUID to generic interface which could be chosen from .bochsrc.
Bochs CPU emulation will enable/disable features (like instruction sets) according to CPUID that is selected.
TODO: Add database of CPUID from real hardware CPUs
