Steve Capper c2c93e5b7f arm64: mm: Introduce PTE_WRITE ... We have the following means for encoding writable or dirty ptes: PTE_DIRTY PTE_RDONLY !pte_dirty && !pte_write 0 1 !pte_dirty && pte_write 0 1 pte_dirty && !pte_write 1 1 pte_dirty && pte_write 1 0 So we can't distinguish between writable clean ptes and read only ptes. This can cause problems with ptes being incorrectly flagged as read only when they are writable but not dirty. This patch introduces a new software bit PTE_WRITE which allows us to correctly identify writable ptes. PTE_RDONLY is now only clear for valid ptes where a page is both writable and dirty.
