hw_pte_t *. Update the i915 remap and selftest callbacks to match the new type. Continue to use ptep_get() for software PTE values and set_pte_at() for updates. The type remains an alias of pte_t on x86 until that architecture opts in. Signed-off-by: Muhammad Usama Anjum --- Changes since v1: - Use software PTE value terminology.
