Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6
* '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.
