This is a reworked version of the same patch, where I can now boot into
a x86_64 Linux kernel.
I rewrote all the access functions for the VMCB, so this time everything
should work just fine on BE-machines. As suggested I moved the injection
detection to translate.c, so the non-virtualized machine should be as
fast as before (w/o svm support), while the virtual one got a speed
boost from that as well.
I removed the EIP hack and set EIP every time an interception occurs, so
unlike the previous version this patch really should have no negative
effect on speed any more.

If any of the people on this list using SVM (kvm developers, maybe xen
developers) could have a deep look into this I'd be really thankful.

Some notes:

- Saving and restoring CC_SRC and CC_DST is not correct as they do not belong to the real processor state. You must save and restore eflags correctly instead.

- Avoid using macros when inline functions suffice.
