Kirill A. Shutemov 235a8f0286 mm: define default PGTABLE_LEVELS to two 
By this time all architectures which support more than two page table
levels should be covered.  This patch add default definiton of
PGTABLE_LEVELS equal 2.

We also add assert to detect inconsistence between CONFIG_PGTABLE_LEVELS
and __PAGETABLE_PMD_FOLDED/__PAGETABLE_PUD_FOLDED.
