Well, to be honest I expected dependencies like this to be there,
and hence I didn't expect it would be a straightforward change.
Just like we do e.g. for the IOMMU enabling, I guess the boolean
wants to become a tristate then (off -> enabling -> enabled),
which interested sites then can use to distinguish what they
want/need to do.
Another relatively obvious solution would be to add a boolean
parameter to altp2m_vcpu_update_p2m() such that
altp2m_vcpu_initialise() can guide it properly. But this of course
depends to a certain degree on how wide spread the problem is.
Fair enough, I'll attempt V2 with the second suggestion (adding a bool
to altp2m_vcpu_update_p2m()).
