* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6: (27 commits)
  parisc: use generic atomic64 on 32-bit
  parisc: superio: fix build breakage
  parisc: Fix PCI resource allocation on non-PAT SBA machines
  parisc: perf: wire up sys_perf_counter_open
  parisc: add task_pt_regs macro
  parisc: wire sys_perf_counter_open to sys_ni_syscall
  parisc: inventory.c, fix bloated stack frame
  parisc: processor.c, fix bloated stack frame
  parisc: fix compile warning in mm/init.c
  parisc: remove dead code from sys_parisc32.c
  parisc: wire up rt_tgsigqueueinfo
  parisc: ensure broadcast tlb purge runs single threaded
  parisc: fix "delay!" timer handling
  parisc: fix mismatched parenthesis in memcpy.c
  parisc: Fix gcc 4.4 warning in lba_pci.c
  parisc: add parameter to read_cr16()
  parisc: decode_exc.c should include kernel.h
  parisc: remove obsolete hw_interrupt_type
  parisc: fix irq compile bugs in arch/parisc/kernel/irq.c
  parisc: advertise PCI devs after "assign_resources"
  ...

Manually fixed up trivial conflicts in tools/perf/perf.h due to addition
of SH vs HPPA perf-counter support.
