drm drivers, intel drm i915 driver (meteor lake, dg2 and older excluding poulsbo, moorestown and derivative), the rest · Maintainers:

apply_to_page_range() now passes PTE table storage to its callback as hw_pte_t *. Update the i915 remap and selftest callbacks to match the new type. Continue to use ptep_get() for logical values and set_pte_at() for updates. The type remains an alias of pte_t on x86 until that architecture opts in.
