From fdc6edbb31fba76fd25d7bd016b675a92908d81e Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Mon, 17 Aug 2020 06:03:26 +0000 Subject: [PATCH] powerpc/fixmap: Fix the size of the early debug area Commit ("03fd42d458fb powerpc/fixmap: Fix FIX_EARLY_DEBUG_BASE when page size is 256k") reworked the setup of the early debug area and mistakenly replaced 128 * 1024 by SZ_128. Change to SZ_128K to restore the original 128 kbytes size of the area.
