Subject: xtensa/cpu: Mark cpu_die() __noreturn
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=69dee6f0338a20c76a7bc61c0a6b59f25e1b25c8;p=linux.git

xtensa/cpu: Mark cpu_die() __noreturn

cpu_die() doesn't return.  Annotate it as such.  By extension this also
makes arch_cpu_idle_dead() noreturn.
