Actually I see no good reason to enforce no-exec at all if we can't do it consistently. And if we're not going to enforce it then there is no point whinging about it. When I applied Segher's original patch I thought that we had the read-implies-exec stuff enabled for the affected CPUs, but it turns out we don't. (We only have that stuff turned on for 32-bit processes on 64-bit cpus - see elf_read_implies_exec in include/asm-powerpc/elf.h.)
