From f3a2ac05894b57e78cd6cc0adba1de642034d940 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 14 Aug 2019 12:36:12 +0000 Subject: [PATCH] powerpc/ptdump: get out of note_prot_wx() when CONFIG_PPC_DEBUG_WX is not selected. When CONFIG_PPC_DEBUG_WX, note_prot_wx() is useless. Get out of it early and inconditionnally in that case, so that GCC can kick all the code out.
