Subject: [PATCH 0/7] Prepare 8xx for CONFIG_STRICT_KERNEL_RWX
Date: Wed, 12 Jul 2017 12:08:43 +0200 (CEST) [thread overview]
Message-ID: <cover.1499633349.git.christophe.leroy@c-s.fr> (raw)
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
