Thanks!

 I just ran into another build error with KAISER:

arch/x86/mm/kaiser.c:173:28: error: '__GFP_NOTRACK' undeclared (first
use in this function); did you mean '__GFP_NOFAIL'?

When you do the update, can you check that it doesn't reference __GFP_NOTRACK?
Apparently the flag got removed in 4.15-rc1.
