Sender: owner-linux-mm@kvack.org Precedence: bulk X-Loop: owner-majordomo@kvack.org List-ID: List-Subscribe: List-Unsubscribe: Generic PTE range and remapping helpers now pass pointers to PTE table storage as hw_pte_t *. Update the Xen callbacks to match those interfaces. Keep software PTE values as pte_t and continue to access them through the existing PTE helpers. This is required when Xen is built for an architecture that selects the distinct hw_pte_t wrapper. Reviewed-by: Juergen Gross Signed-off-by: Muhammad Usama Anjum --- Changes since v1: - Use software PTE value terminology. Changes since RFC v1: - Clarify why the callback conversion is required after architecture opt-in. --- drivers/xen/gntdev.c | 2 +- drivers/xen/privcmd.c | 2 +- drivers/xen/xenbus/xenbus_client.c | 2 +- drivers/xen/xlate_mmu.c | 4 ++-- 4 files changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/xen/gntdev.c b/drivers/xen/gntdev.c index 1dcc4675580ed..b013bcad99b5b 100644 --- a/drivers/xen/gntdev.c +++ b/drivers/xen/gntdev.c @@ -301,7 +301,7 @@ void gntdev_put_map(struct gntdev_priv *priv, struct gntdev_grant_map *map) /* ------------------------------------------------------------------ */ -static int find_grant_ptes(pte_t *pte, unsigned long addr, void *data) +static int find_grant_ptes(hw_pte_t *pte, unsigned long addr, void *data) { struct gntdev_grant_map *map = data; unsigned int pgnr = (addr - map->pages_vm_start) >> PAGE_SHIFT; diff --git a/drivers/xen/privcmd.c b/drivers/xen/privcmd.c index 7cfc28f1bb86f..e724cc053e264 100644 --- a/drivers/xen/privcmd.c +++ b/drivers/xen/privcmd.c @@ -1658,7 +1658,7 @@ static int privcmd_mmap(struct file *file, struct vm_area_struct *vma) * on a per pfn/pte basis.
