From 64d70277114b069579c96e6daf83922b9eacc383 Mon Sep 17 00:00:00 2001 From: David Edmondson Date: Tue, 2 Mar 2021 09:03:14 +0000 Subject: [PATCH] elf_ops: correct loading of 32 bit PVH kernel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Because sizeof(struct elf64_note) == sizeof(struct elf32_note), attempting to use the size of the currently defined struct elf_note as a discriminator for whether the object being loaded is 64 bit in load_elf() fails. Instead, take advantage of the existing glue parameter SZ, which is defined as 32 or 64 in the respective variants of load_elf().
