Subject: [PATCH 0/3] powerpc/8xx: Implementation of execute protection
Date: Wed, 22 Apr 2015 12:06:39 +0200 (CEST) [thread overview]
Message-ID: <cover.1429694647.git.christophe.leroy@c-s.fr> (raw)
This patchset implements execute protection on the 8xx.
It also simplifies the handling of PAGE_USER and PAGE_RO,
and adds a small fix to the kernel pages definition.
This patchset goes on to of my previous patchset named
"[v5] powerpc8xx: Further optimisation of TLB handling"
Christophe Leroy (3):
powerpc/8xx: mark _PAGE_SHARED all types of kernel pages
powerpc/8xx: Handle PAGE_USER via APG bits
powerpc/8xx: Implementation of PAGE_EXEC
