how set_pte_at()'s vaddr and ptep args relate
Hi Zach,
I'm wondering what the interface requirements of set_pte_at()'s "addr"
and "ptep" args are. I presume that in general the ptep points to the
pte entry which corresponds to the vaddr, but is this necessarily the case?
For example, it is valid to pass a non-highmem page kmap_atomic(), which
will simply return a direct pointer to the page.
