On Cavium's thunder processor the cache line size is going to be
bigger than 64 bytes, what is your solution to improve performance on
target's like Thunder?

Also I think the default page size for most Linux distros is going to
be 64k on aarch64 including Redhat Linux so it makes sense not to
define FIXED_PAGE_SIZE.

I will implement the ILP32 version of this patch once it goes in,
there needs a few changes in gtm_jmpbuf due to long and pointers being
32bit but the assembly storing 64bits always.

Thanks,
Andrew
