[PATCHv2 0/3] powerpc: kprobes insn page fixes

["Ritesh Harjani (IBM)" <ritesh.list@gmail.com>]

Hi All,

A few fixes that came out of looking at a W+X warning at boot with
KPROBES=y and MODULES=n.

- Patch-1 fixes that warning.
- Patch-2 (reported by Sashiko) fixes an oops on book3s/32 when a kprobe has to
  single step an instruction out of line, the insn page was in an NX segment.
- Patch-3 makes ptdump show "X" for kernel mappings on e500, which was noticed
  while testing the other two.

Ritesh Harjani (IBM) (3):
  powerpc/execmem: Don't leave kprobes insn pages W+X when CONFIG_MODULES=n
  powerpc/execmem: Allocate kprobes insn pages from the modules area on book3s/32
  powerpc/ptdump: Show the exec flag of kernel mappings on e500
