arm64: define BUG() instruction without CONFIG_BUG
commit
f13d52cb3fad03c237572be2ee691e1fe2d1d7bb upstream.
This mirrors commit
e9c38ceba8d9 ("ARM: 8455/1: define __BUG as
asm(BUG_INSTR) without CONFIG_BUG") to make the behavior of
arm64 consistent with arm and x86, and avoids lots of warnings in
randconfig builds, such as:
kernel/seccomp.c: In function '__seccomp_filter':
kernel/seccomp.c:666:1: error: no return statement in function returning non-void [-Werror=return-type]
