From 19fc577579c86fec6e2523baeb457b02e939796f Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Wed, 4 Mar 2015 13:27:34 +0000 Subject: [PATCH] arm64: fixmap: make FIX_TEXT_POKE0 permanent The FIX_TEXT_POKE0 is currently at the end of the temporary fixmap slots, despite the fact that it can be used at any point during runtime (e.g. for poking the text of loaded modules), and thus should be a permanent fixmap slot (as is the case on arm and x86). This patch moves FIX_TEXT_POKE0 into the set of permanent fixmap slots.
