Subject: [PATCH] init: fix build with older gcc
Date: Fri, 24 Jun 2016 03:29:03 -0600	[thread overview]
Message-ID: <576D197F02000078000F8687@prv-mh.provo.novell.com> (raw)

__setup_str is used on arrays of char, so there aren't any relocatable
items. Hence __initconst has to be used here, not __initconstrel.

Whatever led to the revert of commit 59b151d2c0 (the original version
of a6066af5b1 "xen/init: Annotate all command line parameter
infrastructure as const" must have got addressed meanwhile - with the
patch here I can't see that old gcc (4.3ish) report a section type
conflict anymore.
