Ideas, comments? I'll send the attachment as a PATCH later (if there are no better suggestions).This will work. An alternative way would be to explicitly name the input file in the section commands, without renaming the section: @@ -126,6 +126,7 @@ SECTIONS _text = .; _stext = .; /* bootstrapping code */ + KEEP(vmlinux.a:head64.o(.head.text)) HEAD_TEXT TEXT_TEXT But I guess not all arch's name their must-be-first file head64.o (or even have such requirement), so that's probably still arch-dependend and hence not inherently better than your way.
The downside of this is that it doesn't make sure the function (startup_64()) is the first one. When someone sticks something before it, it breaks again. But leaving the decision up to the x86 maintainers ;).
Re. other archs, I have absolutely no idea (haven't looked into that at all).
thanks, -- js
