Hi Johannes,

It's probably a bug fix that unveils the link errors.

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   2178cbc68f3602dc0b5949b9be2c8383ad3d93ef
commit: 489c2a20a414351fe0813a727c34600c0f7292ae mm: memcontrol: introduce CONFIG_MEMCG_LEGACY_KMEM
date:   3 weeks ago
config: x86_64-randconfig-s3-02101458 (attached as .config)
reproduce:
        git checkout 489c2a20a414351fe0813a727c34600c0f7292ae
        # save the attached .config to linux build tree
        make ARCH=x86_64 

All errors (new ones prefixed by >>):

   arch/x86/built-in.o: In function `uv_bios_call':

I'd be surprised if the above patch caused this.

CONFIG_EFI=n

CONFIG_X86_UV does not depend on EFI.

X86_UV ought to depend on EFI.
