Subject: [PATCH] arch/arm64/include/asm/jump_label.h: use asm_volatile_goto
Date: Sun, 9 Sep 2018 17:47:31 +0200 [thread overview]
Message-ID: <20180909154731.GA20381@gmail.com> (raw)
All other uses of "asm goto" go through asm_volatile_goto
(including the arm version of the same file). For consistency,
use it here as well.
