From 9c3264ce40130966897fb9c1b91c120f588531d0 Mon Sep 17 00:00:00 2001 From: Bradley Bolen Date: Fri, 26 Jan 2018 22:11:04 -0500 Subject: [PATCH] atomic-long: Fix warnings on arm64 Several inline functions in this file reference undefined functions in U-Boot. For example: atomic-long.h:73:9: warning: implicit declaration of function 'atomic64_sub_and_test' atomic-long.h:80:9: warning: implicit declaration of function 'atomic64_dec_and_test' atomic-long.h:87:9: warning: implicit declaration of function 'atomic64_inc_and_test' Handle this the same as the 32 bit build by wrapping these functions in a __UBOOT__ check.
