Disable it to keep this patch series bisectable.

To disable the use of the Nested Paging feature even if it is available in
hardware this patch adds a module parameter. Nested Paging can be disabled by
passing npt=0 to the kvm_amd module.

These are the first forty of about a hundred patches I have queued for 2.6.26.
Note that a few will go through git-s390, maybe a couple through x86.git, and
a few to 2.6.25-rc.
The ia64 patches are not included as they are being reviewed, but I hope to have
them merged in time for the 2.6.26

Certain x86 instructions use bits 3:5 of the byte following the opcode as an
opcode extension, with the decode sometimes depending on bits 6:7 as well.
Add support for this in the main decoding table rather than an ad-hock
adaptation per opcode.

Unfortunately, this is still broken:

I converted everything to use offsetof but left the accessors. You need
a fair number of macros to handle the various data sizes and even then,
I think it ends up looking nicer with the macros. See my patch series
on qemu-devel and let me know if you agree/disagree.
