From 99ad503287daf78e19e64e0e51f1d60a2a592217 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 9 Feb 2017 23:55:43 +1100 Subject: [PATCH] powerpc: Add a prototype for mcount() so it can be versioned Currently we get a warning that _mcount() can't be versioned: WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. Add a prototype to asm-prototypes.h to fix it. The prototype is not really correct, mcount() is not a normal function, it has a special ABI. But for the purpose of versioning it doesn't matter.
