[PATCH RFC 11/11] xen: use hw_pte_t for PTE range callbacks
From: Muhammad Usama Anjum <hidden>
Date: 2026-07-27 16:49:17

Subsystem:
the rest, xen hypervisor interface · Maintainers:
Linus Torvalds, Juergen Gross, Stefano Stabellini
Generic PTE range and remapping helpers now pass pointers to PTE table storage as hw_pte_t *. Update the callbacks to match those interfaces. Keep logical PTE values as pte_t and continue to access them through the existing PTE helpers.
