Subject: [PATCH] bogus symbol used in arch/um/os-Linux/elf_aux.c
X-Git-Tag: accepted/tizen/common/20141203.182822~43527
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=95608261dae863bc43292e6fbd946a3abd3aa49f;p=platform%2Fkernel%2Flinux-arm64.git

[PATCH] bogus symbol used in arch/um/os-Linux/elf_aux.c

elf_aux is userland code; it uses symbol (ELF_CLASS) that doesn't exist in
userland headers; pulled into kernel-offsets.h, switched elf_aux to using it.
