Christophe Leroy daba790242 powerpc/mm: add pte helpers to query and change pte flags ... In order to avoid using generic _PAGE_XXX flags in powerpc core functions, define helpers for all needed flags: - pte_mkuser() and pte_mkprivileged() to set/unset and/or unset/set _PAGE_USER and/or _PAGE_PRIVILEGED - pte_hashpte() to check if _PAGE_HASHPTE is set. - pte_ci() check if cache is inhibited (already existing on book3s/64) - pte_exprotect() to protect against execution - pte_exec() and pte_mkexec() to query and set page execution - pte_mkpte() to set _PAGE_PTE flag. - pte_hw_valid() to check _PAGE_PRESENT since pte_present does something different on book3s/64. On book3s/32 there is no exec protection, so pte_mkexec() and pte_exprotect() are nops and pte_exec() returns always true.
