Subject: [PATCH -tip v4 1/4] x86/asm: Allow to pass macros to __ASM_FORM()
Date: Fri,  6 Sep 2019 22:13:48 +0900	[thread overview]
Message-ID: <156777562873.25081.2288083344657460959.stgit@devnote2> (raw)
In-Reply-To: <156777561745.25081.1205321122446165328.stgit@devnote2>

Use __stringify() at __ASM_FORM() so that user can pass
code including macros to __ASM_FORM().
