From a5bdc451c7d10056acd9b49f6028895451b37df5 Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Fri, 3 May 2024 03:44:46 +0200 Subject: physmem: Replace check for RAMBlock offset 0 with xen_mr_is_memory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For xen, when checking for the first RAM (xen_memory), use xen_mr_is_memory() rather than checking for a RAMBlock with offset 0. All Xen machines create xen_memory first so this has no functional change for existing machines. Signed-off-by: Edgar E.
