[PATCH v13 01/14] ARM: mm: add missing pud_page define to 2-level page tables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ARM uses its own PMD folding scheme which is missing pud_page which
should just pass through to pmd_page. Move this from the 3-level
page table to common header.
