Subject: elf: use ELF_CORE_EFLAGS for kcore ELF header flags.
From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxxx>
ELF_CORE_EFLAGS is already used by the binfmt_elf coredumper to set correct
arch specific ELF header flags on coredumps. Use it for kcore as well.
This corrects kcore files for the CRIS arch and I believe it corrects
ordinary coredumps for the H8/300.
