[PATCH v1 0/3] Implement set_memory_xx for ppc64 book3s

[Balbir Singh]

After implementing STRICT_KERNEL_RWX, it turns out that implementing
set_memory_ro/rw/x/nx is quite easy. The first patch is applied on
top (http://patchwork.ozlabs.org/patch/795745/).

The first patch implements the various routines, the second patch
enables ARCH_HAS_SET_MEMORY for PPC_BOOK3S_64 and the third patch
enables the BPF infrastructure to use the set_memory_ro and
set_memory_rw routines.

Balbir Singh (3):
  arch/powerpc/set_memory: Implement set_memory_xx routines
  Enable ARCH_HAS_SET_MEMORY
  arch/powerpc/net/bpf: Basic EBPF support
