From: Helge Deller Date: Wed, 1 May 2019 12:59:58 +0000 (+0200) Subject: parisc: Allow live-patching of __meminit functions X-Git-Tag: v5.0.19~115 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fac8648ec7cec6d693c17f473c5eb2b5f3b67a1c;p=thirdparty%2Fkernel%2Fstable.git parisc: Allow live-patching of __meminit functions commit d19a12906e5e558c0f6b6cfece7b7caf1012ef95 upstream. 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.
