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] Clean up linker script using standard macros. [IA64] Use standard macros for page-aligned data. [IA64] Use .ref.text, not .text.init for start_ap. [IA64] sgi-xp: fix printk format warnings [IA64] ioc4_serial: fix printk format warnings [IA64] mbcs: fix printk format warnings [IA64] pci_br, fix infinite loop in find_free_ate() [IA64] kdump: Short path to freeze CPUs [IA64] kdump: Try INIT regardless of [IA64] kdump: Mask INIT first in panic-kdump path [IA64] kdump: Don't return APs to SAL from kdump [IA64] kexec: Unregister MCA handler before kexec [IA64] kexec: Make INIT safe while transition to [IA64] kdump: Mask MCA/INIT on frozen cpus Fix up conflict in arch/ia64/kernel/vmlinux.lds.S as per Tony's suggestion.
