Generate include/generated/generic-asm-offsets.h and include/generated/asm-offsets.h in ./Kbuild. This commit also changes the include guard. Before this commit, __ASM_OFFSETS_H__ was used for both of them. So we could not include generic-asm-offsets.h and asm-offsets.h at the same time. This commit renames the include guard of the former to __GENERIC_ASM_OFFSETS_H__. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
