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
