Subject[PATCH 00/19] expose page table levels on Kconfig leve
Date
I've failed my attempt on split up mm_struct into separate header file to
be able to use defines from <asm/pgtable.h> to define mm_struct: it causes
too much breakage and requires massive de-inlining of some architectures
(notably ARM and S390 with PGSTE).

This is other approach: expose number of page table levels on Kconfig
level and use it to get rid of nr_pmds in mm_struct.

Kirill A. Shutemov (19):
alpha: expose number of page table levels on Kconfig level
arm64: expose number of page table levels on Kconfig level
arm: expose number of page table levels on Kconfig level
frv: mark PUD and PMD folded
ia64: expose number of page table levels on Kconfig level
m32r: mark PMD folded
m68k: mark PMD folded and expose number of page table levels
mips: expose number of page table levels on Kconfig level
mn10300: mark PUD and PMD folded
parisc: expose number of page table levels on Kconfig level
powerpc: expose number of page table levels on Kconfig level
s390: expose number of page table levels
sh: expose number of page table levels
sparc: expose number of page table levels
tile: expose number of page table levels
um: expose number of page table levels
x86: expose number of page table levels on Kconfig level
mm: define default PGTABLE_LEVELS to two
mm: do not add nr_pmds into mm_struct if PMD is folded
