From 94ef7ecbdf6f7d7f13bdf44b9eab4001e71208d6 Mon Sep 17 00:00:00 2001 From: Dave Martin Date: Tue, 31 Oct 2017 15:50:54 +0000 Subject: arm64: fpsimd: Correctly annotate exception helpers called from asm A couple of FPSIMD exception handling functions that are called from entry.S are currently not annotated as such. This is not a big deal since asmlinkage does nothing on arm/arm64, but fixing the annotations is more consistent and may help avoid future surprises. This patch adds appropriate asmlinkage annotations for do_fpsimd_acc() and do_fpsimd_exc().
