With your changes this boots and gets into the test suite, but there is
a fault here:

task::pagefault................. Warning: faulting task 0xffff000040452000 has no fault handler
Page fault @ address 7fff7ffeff70 from ip 80c824; 10010010000000000000000001000111

This is probably related to the new uapi fault handling logic not being
tested in aarch64. Will investigate myself if you don't get to it first.
