Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6
* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
[IA64] Avoid array overflow if there are too many cpus in SRAT table
[IA64] Remove unlikely from cpu_is_offline
[IA64] irq_ia64, use set_irq_chip
[IA64] perfmon: Change vmalloc to vzalloc and drop memset.
[IA64] eliminate race condition in smp_flush_tlb_mm
