x86_64 allyesconfig has screwed up voffset and blows up KVM

[Andy Lutomirski]

I'm testing 39bfe90706ab0f588db7cb4d1c0e6d1181e1d2f9.  I'm not sure
what's going on here.

voffset.h contains:

#define VO__end 0xffffffff8111c7a0
#define VO__end 0xffffffff8db9a000
#define VO__text 0xffffffff81000000

because

$ nm vmlinux|grep ' _end'
ffffffff8111c7a0 t _end
ffffffff8db9a000 B _end


Booting the resulting image says:
