As PP00 is used for # non _PAGE_USER pages, user can't access kernel pages not flagged # _PAGE_USER while kernel can. # # For userspace segments, both kernel and user accesses are performed # with key 0, therefore pages not flagged _PAGE_USER are still # accessible to the user. # # This shouldn't be an issue, because userspace is expected to be # accessible to the user. But unlike most other architectures, powerpc # implements PROT_NONE protection by removing _PAGE_USER flag instead of # flagging the page as not valid. This means that pages in userspace # that are not flagged _PAGE_USER shall remain inaccessible. # # To get the expected behaviour, just mimic other architectures in the # TLB miss handler by checking _PAGE_USER permission on userspace # accesses as if it was the _PAGE_PRESENT bit. # # Note that this problem only is only for 603 cores. The 604+ have # an hash table, and hash_page() function already implement the # verification of _PAGE_USER permission on userspace pages. # # Fixes: f342adca3afc ("powerpc/32s: Prepare Kernel
