[PATCH] reduce alignment constraint on ia64 elf core header

[Neil Horman]

Hey all-
	Patch to reduce the alignment constraints on ia64 elf core headers.
>From what I can see there is no need to align the elf core header structure to
the EFI_PAGE_SIZE (given that the EFI will never read this data, only the kernel
will when booting a kdump kernel).  And since this is going into our reserved
memory, it saves us 3K (4K vs 1K alignment).  Tested successfully by myself on
several ia64 boxes.

Thanks & Regards
Neil
