Descriptor writes need an atomic kvm_set_guest_bit(), no?
It is? atomic against what? Current code just write whole descriptor
using write_std().
These are accessed bit changes, and are done atomically in the same
way as a page table walk sets the accessed and dirty bit.
Presumably the atomic operation is to allow the kernel to scan
segments and swap them out if they are not used.
We can use cmpxchg callback for that, no?
Yes.
