Subject: [PATCH 07/14] x86/unwind/orc: Convert global variables to static
Date: Thu, 12 Mar 2020 12:30:26 -0500	[thread overview]
Message-ID: <63b5cab2e28b9c08854fc57f5b512a9ccf76ad95.1584033751.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1584033751.git.jpoimboe@redhat.com>

These variables aren't used outside of unwind_orc.c, make them static.

Also annotate some of them with '__ro_after_init', as applicable.
