From 08b6d290f977d8145804fd2b9bc2c331f2484f8e Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Wed, 30 Jan 2008 13:33:25 +0100 Subject: xen: fix section usage in xen-head.S and setup.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit additional section for .init.text appending a number. A side effect of this was a section mismatch warning because modpost did not recognize a .init.text section named .init.text.1: WARNING: vmlinux.o(.text.head+0x247): Section mismatch: reference to .init.text.1:start_kernel (between 'is386' and 'check_x87') Fix this by hardcoding the "ax" in the pushsection. Thanks to Torlaf for reporting this. Alan Modra provided the hint that made me able to locate the root cause of this warning. And Mike Frysinger told me how to properly fix it using __INIT/__FINIT. Fix following Section mismatch warning in addition: WARNING: vmlinux.o(.text+0x14c8): Section mismatch: reference to .init.data:vsyscall_int80_start (between 'fiddle_vdso' and 'xen_setup_features') fiddle_vdso was only used from a __init function - so declare it __init.
