[PATCH v2 00/37] Implement execute-only protection on powerpc

2023-09-25 Thread Christophe Leroy
This series reworks _PAGE_FLAGS on all platforms in order to implement execute-only protection on all powerpc. For all targets except 40x and 604 it will be a real execute-only protection as the hardware and/or software allows a distinct protection. For 40x and 604 that's a poor's man
