Hi Sasha, s390 builds in v3.18.y-stable-queue fail as follows. ./arch/s390/include/asm/mmu_context.h: In function 'init_new_context': ./arch/s390/include/asm/mmu_context.h:33:3: error: implicit declaration of function 'mm_inc_nr_pmds' Culprit appears to be 's390/mm: four page table levels vs. fork'. It uses mm_inc_nr_pmds(), which does not exist in v3.18. I noticed that arm64:allmodconfig builds fail as well, but that is not a new problem and only seen with gcc 5.2 (or at least not with gcc 4.9.1). I'll see if I can track this down.
