Subject: [PATCH 0/7] Prepare 8xx for CONFIG_STRICT_KERNEL_RWX

This serie makes the PINning of ITLBs optional in the 8xx
in order to allow STRICT_KERNEL_RWX to work properly

Christophe Leroy (7):
  powerpc/8xx: Ensures RAM mapped with LTLB is seen as block mapped on
    8xx.
  powerpc/8xx: Remove macro that checks kernel address
  powerpc/32: Avoid risk of unrecoverable TLBmiss inside entry_32.S
  powerpc/8xx: Make pinning of ITLBs optional
  powerpc/8xx: Do not allow Pinned TLBs with STRICT_KERNEL_RWX or
    DEBUG_PAGEALLOC
  powerpc/8xx: mark init functions with __init
  powerpc/8xx: Reduce DTLB miss handler by one insn
