[PATCH 0/7] Kernel Userspace protection for PPC32

[Christophe Leroy]

This series intend to implement Kernel Userspace protection for PPC32.
It comes on top of the v4 series for Radix.

Christophe Leroy (6):
  powerpc/8xx: Only define APG0 and APG1
  powerpc/8xx: Add Kernel Userspace Execution Prevention
  powerpc/32: Prepare for Kernel Userspace Access Protection
  powerpc/8xx: Add Kernel Userspace Access Protection
  powerpc/book3s32: Prepare Kernel Userspace Access Protection
  powerpc/book3s32: Implement Kernel Userspace Access Protection

Russell Currey (1):
  powerpc/64s: Implement KUAP for Radix MMU (SQUASH)
