c41cbe6d56 Link traces over taken branch optimization which makes handlers chaining even more efficient. 
I observed 5% speedup in all disk images over 2.6pre1.
The change is safe (passed all regressions) and I will be glad to make it into Bochs 2.6!

cc694377b9 Standartization of Bochs instruction handlers. 
Bochs instruction emulation handlers won't refer to direct fields of instructions like MODRM.NNN or MODRM.RM anymore.
Use generic source/destination indications like SRC1, SRC2 and DST.
All handlers are modified to support new notation. In addition fetchDecode module was modified to assign sources to instructions properly.

Immediate benefits:
- Removal of several duplicated handlers (FMA3 duplicated with FMA4 is a trivial example)
- Simpler to understand fetch-decode code

Future benefits:
- Integration of disassembler into Bochs CPU module, ability to disasm bx_instruction_c instance (planned)

Huge patch. Almost all source files wre modified.

c7c431f88e bx_instr_mem_data_access became completely obsolete with new stack optimization merged into SVN. 
It already had limited usability before. With stack direct access optimization the callback won't be called for stack accesses as well.
See note by Brian Slechta:

=== Cut Hete ===
While using Bochs as a reference model for simulations, the simulator needs
information about what loads/stores are taking place with each instruction.
Presumably,  that  is  what  the BX_INSTR_MEM_DATA() instrumentation macros
cover (which is the place where our simulator hooks up).

The RETnear_xxx() functions call access_linear() directly, rather than call
read_virtual_xxx()  functions. This is a problem for code making use of the
BX_INSTR_MEM_DATA()   hook  because  it  does  not  get  called  for  these
instructions.  Should  this  be  changed along with some other instructions
that exhibit this?
=== Cut Hete ===

For Bryan's usage bx_instr_lin_access and bx_instr_phy_read/bx_instr_phy_write callbacks should be used.

d4688e8b95 - Do not compile support for alignment check (#AC exception) by default 
for CPU emulation performance reasons, the alignment check compilation
    still can be enabled using configure option --enable-alignment-check.

There is no software in the world which enable #AC exception checking, this
x86 feature is completely legacy but its emulation support costs up to 3-5%
emulation speed.

The checking for #AC exception enable still will be done, if

 CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1

but the alignment check is not compiled in, the Bochs will PANIC with corresponding message.
You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.

bd4aa017fe Lazy flags improvement patch by Darek Mihocka - measured 5% speedup everywhere accross the board 
The problem with Parity is it is generally referenced very rarely so the current lazy flags code is not efficient to updated Parify flag only (because it updates low 8 bits of .result value the existing Zero Flag has to be shadowed in .auxbits.
So I flipped it around, to make Parity be shadowed in auxbits.  .result now is only needed to derive Zero Flag, and both Sign and Parify are derived from .result + .auxbits (as Zero Flag is now).  For the 90% of the conditional jumps that are JZ or JNZ, this is a speedup.
Parity is now derived from 8 bits in .result and 8 bits in .auxbits, and Sign is derived from one flag in .result and 1 bit in .auxbits by XOR-ing them all together.  It makes the code sequences for SAHF and POPF simpler too.

------------

Implemented SVN nested paging support - the Virtual Box boots perfectly with Nested Paging guest !
A lot of code duplication was added for now - major cleanup will follow later.

! Added AMD Phenom X3 8650 (Toliman) configuration to the CPUDB - this configuration has Nested Paging enabled.

Some CPUID modules rework done to enable Toliman configuration.

Ckean up 'executable' attribute from all CPU source files.

4d0a5c1b07 - VMX: EPT misconfiguration should always take priority above EPT permissions violation (translate_guest_physical corner case bug) 
- VMX: EPT reserved bits set should cause EPT misconfiguration and not EPT violation
- VMX: EPT walk for guest CR3 address should be considered as 'page walk'

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.

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.
