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
