Subject: [PATCH 02/15] arm64: add scs_patch_vmlinux prototype

From: Arnd Bergmann <arnd@...db.de>

scs_patch_vmlinux() is only called from assembler code, so there
is no prototype, but adding one avoids this warning:

arch/arm64/kernel/patch-scs.c:254:24: error: no previous prototype for function 'scs_patch_vmlinux' [-Werror,-Wmissing-prototypes]
