From 997fc12ec91eccf6b7485565864f3eb8ce74def2 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 16 Feb 2019 15:36:33 +0100 Subject: [PATCH] efi_loader: do not miss last relocation block If the last block in the relocation table contains only a single relocation, the current coding ignores it. Fix the determination of the end of the relocation table.
