[PATCH v10 00/10] powerpc: Further Strict RWX support

[Jordan Niethe]

Another revision to this series adding more Strict RWX support on powerpc, in
particular Strict Module RWX.  This revision adds consideration for bpf.

The changes in v10 for each patch:

Christophe Leroy (2):
  powerpc/mm: implement set_memory_attr()
  powerpc/32: use set_memory_attr()

Jordan Niethe (3):
  powerpc/lib/code-patching: Set up Strict RWX patching earlier
  powerpc: Always define MODULES_{VADDR,END}
    v10: - New to series

  powerpc/bpf: Write protect JIT code
    v10: - New to series

Russell Currey (5):
  powerpc/mm: Implement set_memory() routines
    v10: - WARN if trying to change the hash linear map

  powerpc/kprobes: Mark newly allocated probes as ROX
    v10: - Use __vmalloc_node_range()

  powerpc/mm/ptdump: debugfs handler for W+X checks at runtime
    v10: check_wx_pages now affects kernel_page_tables rather
         then triggers its own action.

  powerpc: Set ARCH_HAS_STRICT_MODULE_RWX
    v10: - Predicate on !PPC_BOOK3S_604
         - Make module_alloc() use PAGE_KERNEL protection

  powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
