From 42f5b4cacd783faf05e3ff8bf85e8be31f3dfa9d Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Wed, 18 May 2016 11:16:50 +1000 Subject: [PATCH] powerpc: Introduce asm-prototypes.h Sparse picked up a number of functions that are implemented in C and then only referred to in asm code. This introduces asm-prototypes.h, which provides a place for prototypes of these functions. This silences some sparse warnings.
