Fix "$(AS) -traditional" compile breakage caused by asmlinkage_protect
git commit 54a015104136974262afa4b8ddd943ea70dec8a2 ("asmlinkage_protect
replaces prevent_tail_call") causes this build failure on s390:
AS arch/s390/kernel/entry64.o
In file included from arch/s390/kernel/entry64.S:14:
include/linux/linkage.h:34: error: syntax error in macro parameter list
make[1]: *** [arch/s390/kernel/entry64.o] Error 1
make: *** [arch/s390/kernel] Error 2
and some other architectures. The reason is that some architectures add
the "-traditional" flag to the invocation of $(AS), which disables
variadic macro argument support.
So just surround the new define with an #ifndef __ASSEMBLY__ to prevent
any side effects on asm code.
