32 bit userland on G5

[Johannes Berg]

Hi,

Since apparently the G5 honours no-execute permissions, shouldn't the 64
bit kernel set the READ_IMPLIES_EXEC personality flag for 32-bit
userland?

The memory being execute-protected is causing a mono bug
(http://bugzilla.ximian.com/show_bug.cgi?id=77028) but I'm not sure
where the correct fix would be, currently the kernel doesn't seem to be
behaving exactly the same on G4 and G5.
