From dfa2a72cdbfc3b7cda196b3389579cff88201ce6 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 13 Mar 2023 13:50:36 +0100 Subject: s390/ftrace: move hotpatch trampolines to mcount.S Move the ftrace hotpatch trampolines to mcount.S. This allows to make use of the standard SYM_CODE macros which again makes sure that the hotpatch trampolines follow the function alignment rules of the rest of the kernel.
