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.

d11114ac19 Patch for emulating target with larger memory than host has available by Gary Cameron. 
The patch was posted in mailing list at Thu 6/16/2011.

Desription for CHANGES:

- Memory
  - Added new configure option which enables RAM file backing for large guest
    memory with a smaller amount host memory, without causing a panic when
    host memory is exhausted (patch by Gary Cameron). To enable configure with
        --enable-large-ramfile option.
