From 471d7ff8b51b63521c8ea35c51966ab4caa434ee Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Wed, 21 Feb 2018 05:08:29 +1000 Subject: powerpc/64s: Remove POWER4 support POWER4 has been broken since at least the change 49d09bf2a6 ("powerpc/64s: Optimise MSR handling in exception handling"), which requires mtmsrd L=1 support. This was introduced in ISA v2.01, and POWER4 supports ISA v2.00.
