From c0ccf6f99e3a43b87980c9df7da48427885206d0 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Thu, 9 Apr 2015 13:51:31 +1000 Subject: jump_label: Allow jump labels to be used in assembly To use jump labels in assembly we need the HAVE_JUMP_LABEL define, so we select a fallback version if the toolchain does not support them. Modify linux/jump_label.h so it can be included by assembly files. We also need to add -DCC_HAVE_ASM_GOTO to KBUILD_AFLAGS.
