With hindsight since writing, I think I can solve the conceptual problem I was having with extra commenting in the linker script. Originally I attempting to coalesce all sections which would have identical superpage permissions, but this isn't exclusive with having these sections separately. Any thoughts about the .reloc section, at least moving it into it to between __init_begin and __init_end so it gets reclaimed on boot? ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
