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.
Fixing the arm64 problem will require patch f5e0a12ca2d9 ("arm64: psci: move psci firmware
calls out of line"). The patch doesn't apply cleanly; there is a minor conflict in the
arm64 Makefile. Let me know if you need me to send a backport.
Thanks,
Guenter
