From ce21726525da53053432b19e27e9fd2a49086d78 Mon Sep 17 00:00:00 2001 From: Claudio Fontana Date: Mon, 22 Mar 2021 14:27:43 +0100 Subject: [PATCH] target/i386: fix host_cpu_adjust_phys_bits error handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit move the check for phys_bits outside of host_cpu_adjust_phys_bits, because otherwise it is impossible to return an error condition explicitly.
