        src/sys/dev/nvmm/x86: nvmm_x86_svm.c

Log Message:
When there's no DecodeAssist in hardware, decode manually in software. This
is needed on certain AMD CPUs (like mine): the segment base of OUTS can be
overridden, and it is wrong to just assume DS.

We fetch the instruction and look at the prefixes if any to determine the
correct segment.
