Does it work at all ?

Linux on arm makes use of a page mapped at the top of the 32-bit address
space containing some "helper" functions to do things like get thread
local storage.

I had a go at adding a pmap_helper() for Linux processes but didn't get
it to work.

Is this still arm or is there a requirement to be able to run an aarch64
application ?

Think we would want newer DRI kernel code to be able to use the Linux
drivers for ARM GPUs, the Mali code makes use of the dri scheduler which
isn't in our tree.
