    xen: suppress abs symbol warnings for unused reloc pointers
    arch/i386/xen/xen-asm.S defines some small pieces of code which are
    used to implement a few paravirt_ops.  They're designed so they can be
    used either in-place, or be inline patched into their callsites if
    there's enough space.
    Some of those operations need to make calls out (specifically, if you
    re-enable events [interrupts], and there's a pending event at that
    time).  These calls need the call instruction to be relocated if the
    code is patched inline.  In this case xen_foo_reloc is a
    section-relative symbol which points to xen_foo's required relocation.
    Other operations have no need of a relocation, and so their
    corresponding xen_bar_reloc is absolute 0.  These are the cases which
    are triggering the warning.
    This patch adds those symbols to the list of safe abs symbols.
