From 0bca3ec846d7a9ea5bddc3b5ab55f6968e690a84 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 20 Apr 2021 18:22:45 +0100 Subject: [PATCH] arm64: Show three registers per line Displaying two registers per line takes 15 lines. That improves to just 10 lines if we display three registers per line, which reduces the amount of information lost when oopses are cut off. It stays within 80 columns and matches x86-64.
