From 4b74a35fc7e9b8efd9067b8a365bab0fefe889ff Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 22 Oct 2020 06:29:31 +0000 Subject: [PATCH] powerpc/32s: Make Hash var static Hash var is used only locally in mmu.c now. No need to set it in head_32.S anymore. Make it static and initialises it to the early hash table.
