Shutemov" I've failed my attempt on split up mm_struct into separate header file to be able to use defines from 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.
