From f31076a6b2391896088fa81755a892213f07788e Mon Sep 17 00:00:00 2001 From: Alaa Mohamed Date: Wed, 20 Apr 2022 01:43:28 +0200 Subject: [PATCH] xen: Convert kmap() to kmap_local_page() kmap() is being deprecated and these usages are all local to the thread so there is no reason kmap_local_page() can't be used. Replace kmap() calls with kmap_local_page().
