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:
Cross-compilation between e.g. i386 -> 64bit could break -> work around it
[IA64] Enable early console for Ski simulator
[IA64] forbid ptrace changes psr.ri to 3
[IA64] Failure to grow RBS
[IA64] Fix processor_get_freq
[IA64] SGI Altix : fix a force_interrupt bug on altix
[IA64] Update arch/ia64/configs/* s/SLAB/SLUB/
[IA64] get back PT_IA_64_UNWIND program header
[IA64] need NOTES in vmlinux.lds.S
[IA64] make unwinder stop at last frame of the bootloader
[IA64] Clean up CPE handler registration
[IA64] Include Kconfig.preempt
[IA64] SN2 needs platform specific irq_to_vector() function.
[IA64] Use atomic64_read to read an atomic64_t.
[IA64] disable irq's and check need_resched before safe_halt
