Please take a look at the following prototype of sharing the PowerPC
VDSO unmap and remap code with other architectures. I've only hooked
up arm64 to begin with. If folks think this is a reasonable approach I
can work on 32 bit ARM as well. Not hearing back from an earlier
request for guidance [1], I simply dove in and started hacking.
Laurent's test case [2][3] is a compelling illustration of whether VDSO
remap works or not on a given architecture.
