From e1288f1db68b30b1efd9a40ef966490631ae6a46 Mon Sep 17 00:00:00 2001 From: Bartosz Szczepanek Date: Wed, 23 Apr 2025 09:05:16 +0000 Subject: [PATCH] efi: Improve logging around memmap init Be more informative if memremap fails, and print out physical address together with size. This change intends to make investigations of such early failures slightly easier.
