From eab1cecc1223378fee700ab6acebf0f39fa6da81 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 31 Jul 2018 12:02:18 +0100 Subject: arm64: sdei: Mark sdei stack helper functions as static The SDEI stack helper functions are only used by _on_sdei_stack() and refer to symbols (e.g. sdei_stack_normal_ptr) that are only defined if CONFIG_VMAP_STACK=y. Mark these functions as static, so we don't run into errors at link-time due to references to undefined symbols. Stick all the parameters onto the same line whilst we're passing through.
