powerpc/mm: Move nohash specifics in subdirectory mm/nohash Many files in arch/powerpc/mm are only for nohash. This patch creates a subdirectory for them. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> [mpe: Shorten new filenames] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

powerpc/nohash: Move setup_kuap out of 8xx.c In order to reuse it on booke/4xx, move KUAP setup routine out of 8xx.c Make them usable on SMP by removing the __init tag as it is called for each CPU. And use __prevent_user_access() instead of hard coding initial lock.

powerpc/fsl_booke/32: implement KASLR infrastructure This patch add support to boot kernel from places other than KERNELBASE. Since CONFIG_RELOCATABLE has already supported, what we need to do is map or copy kernel to a proper place and relocate. Freescale Book-E parts expect lowmem to be mapped by fixed TLB entries(TLB1). The TLB1 entries are not suitable to map the kernel directly in a randomized region, so we chose to copy the kernel to a proper place and restart to relocate. The offset of the kernel was not randomized yet(a fixed 64M is set). We will randomize it in the next patch.
