Hi,
this is version 2 of the patch-set to make the KVM instruction emulator
aware of intercepted instructions. Noting the differences to v1 does not
make a lot of sense this this is basically a re-implementation so that
almost everything changed :-)
The re-write was done on the basis of Avi's patches he sent after the
last discussion. With these changes the implementation in the SVM code
got a lot smaller and more generic (and easier to extend). The big
switch is now only necessary for handling special cases.
Comments and feedback is appreciated.
Regards,
Joerg
