I think this should be handled in qemu, since it isn't really a cpu bit.
But this would require to make an exception for turning this bit on
again after it has been trimmed.
I just made (QEMU) patches for make this trimming really work (and
removing all the hacked bits), so I would like to not spoil this again
by introducing another excecption. After all this is more a list of what
KVM does _not_ support (should we make this a negative one? gets ugly
with the reserved bits), so I would like to leave it here.
I will send out the patches to qemu-devel when I found the last bug.
Regards,
Andre.
