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()
