Add TLB bypass for instruction emulation copyinsn() fetches a userland instruction through the direct map. This lets emulation work with execute-only virtual memory mappings. OK deraadt@ |

Use 64-bit page table entries on octeon This (over-)compensates for the frame bit reduction related to the TLB read inhibit support. However, the memory overhead of page tables is increased. OK miod@ |

Make sure we also remove read access in pmap_page_ro() when the new permissions only allow execution. Make sure we completely invalidate the PTE if the intersection between the old and new permissions is the empty set. ok drahn@, deraadt@, mpi@ |

Implement X-only mappings on sun4u by not letting the dtlb miss handler allow ttes with the "exec only" bit; joint work with deraadt@, unfortunately no effect on sun4v due to the lack of software bits in ttes to fit an "exec only" bit. ok deraadt@ kettenis@ |
