Allow for different LMA vs VMA (logical/virtual memory address).
  IA-64 uses the LMA to tell the bootloader the physical location
  of the image, whereas the VMA as always represents the address the
  image gets mapped to.
  
  The default (used for non IA-64) is LMA == VMA, which is what
  the linker previously assumed anyway.
  
Also:
o remove duplicate .rodata1 section
o __vermagic doesn't need its own section in vmlinux, it can
  just go into .rodata
o .kstrtab hasn't been used since the introduction of the new
  module loader, so it should be deleted from the linker scripts
  as well (except for arch/um, which does not seem up to date
  w.r.t the new module loader yet)
o The kallsyms mechanism has changed to not need its own section,
  so again the references in the linker scripts can go away
