There is no need to copy the whole memslot data after releasing
slots_arch_lock for a moment to install temporary memslots copy in
kvm_set_memslot() since this lock only protects the arch field of each
memslot.
Just resync this particular field after reacquiring slots_arch_lock.
Note, this also eliminates the need to manually clear the INVALID flag
when restoring memslots; the "setting" of the INVALID flag was an
unwanted side effect of copying the entire memslots.
Since kvm_copy_memslots() has just one caller remaining now
open-code it instead.

Heh, I think you can drop my SoB? This is new territory for me, I don't know the
rules for this particular situation.

Will replace your SoB with your R-b on this patch then.
Thanks,
