From 7c8cb4b50f3cc6f4a8f7bfddad6fb5a845df3261 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Tue, 11 Oct 2016 18:47:56 +1100 Subject: powerpc/64s: Fix power4_fixup_nap placement power4_fixup_nap is called from the "common" handlers, not the virt/real handlers, therefore it should itself be a common handler. Placing it down in the trampoline space caused it to go out of reach of its callers, requiring a trampoline inserted at the start of the text section, which breaks the fixed section address calculations.
