This patch includes some generic stuff including elf and ksyms. Because all one-line asm-generic headers are auto-generated by ASM_GENERIC_HEADERS in arch/unicore32/Makefile, so the rest seems very little. ELF handling functions and module handling functions are also here. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Reviewed-by: Arnd Bergmann <arnd@arndb.de>
