Pull s390 fixes from Martin Schwidefsky: - A fix for the pgtable_bytes misaccounting on s390. The patch changes common code part in regard to page table folding and adds extra checks to mm_[inc|dec]_nr_[pmds|puds]. - Add FORCE for all build targets using if_changed - Use non-loadable phdr for the .vmlinux.info section to avoid a segment overlap that confuses kexec - Cleanup the attribute definition for the diagnostic sampling - Increase stack size for CONFIG_KASAN=y builds - Export __node_distance to fix a build error - Correct return code of a PMU event init function - An update for the default configs * tag 's390-4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/perf: Change CPUM_CF return code in event init function s390: update defconfigs s390/mm: Fix ERROR: "__node_distance" undefined! s390/kasan: increase instrumented stack size to 64k s390/cpum_sf: Rework attribute definition for diagnostic sampling s390/mm: fix mis-accounting of pgtable_bytes mm: add mm_pxd_folded checks to pgtable_bytes accounting functions mm: introduce mm_[p4d|pud|pmd]_folded mm: make the __PAGETABLE_PxD_FOLDED defines non-empty s390: avoid vmlinux segments overlap s390/vdso: add missing FORCE to build targets s390/decompressor: add missing FORCE to build targets
