This patch implements STRICT_KERNEL_RWX on PPC32. As for CONFIG_DEBUG_PAGEALLOC, it deactivates BAT and LTLB mappings in order to allow page protection setup at the level of each page. As BAT/LTLB mappings are deactivated, there might be a performance impact. Signed-off-by: NChristophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>
