Merge tag 'for-linus-20130509' of git://git.infradead.org/~dwmw2/random-2.6

Pull misc fixes from David Woodhouse:
 "This is some miscellaneous cleanups that don't really belong anywhere
  else (or were ignored), that have been sitting in linux-next for some
  time.  Two of them are fixes resulting from my audit of krealloc()
  usage that don't seem to have elicited any response when I posted
  them, and the other three are patches from Artem removing dead code."

* tag 'for-linus-20130509' of git://git.infradead.org/~dwmw2/random-2.6:
  pcmcia: remove RPX board stuff
  m68k: remove rpxlite stuff
  pcmcia: remove Motorola MBX860 support
  params: Fix potential memory leak in add_sysfs_param()
  dell-laptop: Fix krealloc() misuse in parse_da_table()
