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. 1. https://lkml.org/lkml/2016/3/2/225 2. https://lists.openvz.org/pipermail/criu/2015-March/019161.html 3. http://lists.openvz.org/pipermail/criu/attachments/20150318/f02ed9ea/attachment.bin Thanks, Christopher Covington -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
