VMI and kmap_atomic_pte paravirt_op

[Ian Campbell]

Hi Alok,

How critical is the vmi_kmap_atomic_pte pv_mmu_op hook to VMI? Is it
required for correct functionality or is it simply an optimisation?

We think we may be able to do away with the Xen version of the hook and
if VMI (which is deprecated) can live without it and you agree then I'll
cook up a patch to remove it altogether.

Thanks,
Ian.
