  the fault is a EXE fault or R/W fault.

- mask/or the SR_NOEXEC bit into the segment register value
  when the number of executable pages becomes 0/non-zero.

- create segments with SR_NOEXEC set, will be cleared when first
  exec mapping in the segment is created.

- allow pte_spill_X() to deal with a new type of fault, page mapped
  but non executable, when execute was requested.

Adds up to - non-exec stack support for powerpc.
