Subject: [PATCH -resend 07/27] x86: boot, annotate local functions
Date: Thu, 10 May 2018 10:06:24 +0200 [thread overview]
Message-ID: <20180510080644.19752-8-jslaby@suse.cz> (raw)
In-Reply-To: <20180510080644.19752-1-jslaby@suse.cz>
relocated, paging_enabled, and no_longmode are self-standing local
functions, annotate them as such. paging_enabled is annotated as
NOALIGN, since the trampoline code has to be compact.
