From 2e82ca3c3978d441ab272a7a964d03c6d2ee2bf3 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 23 Aug 2017 23:56:21 +1000 Subject: [PATCH] powerpc/oops: Print the kernel's endian in the oops Although the MSR tells you what endian you're in it's possible that isn't the same endian the kernel was built for, and if that happens you're usually having a very bad day. So print a marker to make it 100% clear which endian the kernel was built for.
