Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
Pull m68knommu from Greg Ungerer: "This contains five fixes. Four fix build problems introduced by recent clean up and merging of the m68k timer and ptrace code. The other fixes the 528x ColdFire CPU QSPI base address definition, missed in the ColdFire QSPI cleanup." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: m68k: make syscall_trace_enter/leave exist for non-MMU classic m68k types m68knommu: fix 68360 local setting of timer interrupt handler m68knommu: fix 68328 local setting of timer interrupt handler m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU types m68knommu: m528x qspi definition fix
