Hi Andrey,

I tried this patchset, with the latest gcc, and I'm seeing the following:

arch/x86/kernel/head.o: In function `_GLOBAL__sub_I_00099_0_reserve_ebda_region':
/home/sasha/linux-next/arch/x86/kernel/head.c:71: undefined reference to `__asan_init_v4'
init/built-in.o: In function `_GLOBAL__sub_I_00099_0___ksymtab_system_state':
/home/sasha/linux-next/init/main.c:1034: undefined reference to `__asan_init_v4'
init/built-in.o: In function `_GLOBAL__sub_I_00099_0_init_uts_ns':
/home/sasha/linux-next/init/version.c:50: undefined reference to `__asan_init_v4'
init/built-in.o: In function `_GLOBAL__sub_I_00099_0_root_mountflags':
/home/sasha/linux-next/init/do_mounts.c:638: undefined reference to `__asan_init_v4'
init/built-in.o: In function `_GLOBAL__sub_I_00099_0_rd_prompt':
/home/sasha/linux-next/init/do_mounts_rd.c:361: undefined reference to `__asan_init_v4'
init/built-in.o:/home/sasha/linux-next/init/do_mounts_md.c:312: more undefined references to `__asan_init_v4' follow


What am I missing?


Thanks,
Sasha
