Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/kyle/parisc-2.6: parisc: Fixup last users of irq_chip->typename parisc: convert /proc/pdc/{lcd,led} to seq_file parisc: Convert BUG() to use unreachable() parisc: Replace old style lock init in smp.c parisc: use sort() instead of home-made implementation (v2) parisc: add CALLER_ADDR{0-6} macros parisc: remove unused IRQSTAT_SIRQ_PEND and IRQSTAT_SZ defines parisc: remove duplicated #include
