Netware writes and reads to the DEBUGCTL and LAST*IP MSRs without

make it happy we should just make them stubs, which is exactly what
SVM already does.
To support VMX too, I put these in the generic code. Maybe the SVM
code could be cleaned up to use generic code too.
I would prefer if you put that into the VMX specific code. We can't move
the SVM parts of it into generic code because Barcelona has hardware
support to virtualize these registers. Therefore SVM don't need that
in generic code.
The code path is svm_set_msr -> kvm_set_msr_common, so even if it is in
the common code path, you can still override it in svm specific code.

I have a truly marvellous patch that fixes the bug which this
