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.
