Currently we use pv-ops to tell linux not to do anything on

While the basic idea is good IMHO, I don't see why we would need
pv-ops
for that. The io delay function already has a switch that can do
nothing
if you're so inclined.
So here's a patch (stacked on top of the previous pv-ops series)
that
removes the io delay pv-ops hook and just sets the native io delay
variable instead.
Can you just get rid of the io_delay op altogether? If KVM
doesn't need
it, then nobody does.
Sure, can do. That'd be a separate patch though.
Yep. A patch each for VMI and Xen to remove the dependency, and a
final
patch to remove the op. Hm, looks like VMI has a specific ROM call
for
io_delay; I wonder what it does.
Oh so it's actually using it? Feel like doing the removal then? I
don't really want to mess with VMI code :-)
