Subject: elf: use ELF_CORE_EFLAGS for kcore ELF header flags
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=79885b227740b9c7d3057f2de556f4098d37cc8f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

elf: use ELF_CORE_EFLAGS for kcore ELF header flags

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 dumps as well.
At the moment, this affects the CRIS and the H8300 arch.
