* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k: parport_mfc3 - Not makes it a bool before the comparison.
  m68k: don't export static inline functions
  fbdev: atafb - add palette register check
  m68k: Remove the BKL from sys_execve
  m68k: Cleanup linker scripts using new linker script macros.
  m68k: Make thread_info.h usable from assembly.
  m68knommu: define arch_has_single_step() and friends
  m68k: ptrace fixes
  m68k: use generic code for ptrace requests
  rtc: Add an RTC driver for the Ricoh RP5C01
  rtc: Add an RTC driver for the Oki MSM6242
