From d19a12906e5e558c0f6b6cfece7b7caf1012ef95 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Wed, 1 May 2019 14:59:58 +0200 Subject: [PATCH] parisc: Allow live-patching of __meminit functions When making the text sections writeable with set_kernel_text_rw(1), include all text sections including those in the __init section. Otherwise functions marked with __meminit will stay read-only.
