Merge git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async
* git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async: async: don't do the initcall stuff post boot bootchart: improve output based on Dave Jones' feedback async: make the final inode deletion an asynchronous event fastboot: Make libata initialization even more async fastboot: make the libata port scan asynchronous fastboot: make scsi probes asynchronous async: Asynchronous function calls to speed up kernel boot
