The Kconfig for PAX_PAGEEXEC doesn't have a dependency on ARM, but there are changes in the arch/arm tree.
Is it supported or is something else missing?

it's an implicit dependency, PAX_PAGEEXEC depends on PAX_NOEXEC which in turn depends on all the archs where it's supported.

yes, PAGEEXEC works on ppc too, i think paxtest will at least trigger the non-exec violations (you can check it in dmesg). pax_handle_fetch_fault is a stub function that would handle various insn emulations (gcc trampolines, etc) but i never had the time or interest to do it myself.
