This adds a selftest subtarget that can be used to verify the accuracy of the usercopy fixup routines.
The patch contains a test module that integrates with the selftest framework and can be specified as a subtarget for the arm64 selftest target. It can be invoked through the same method as the other subtargets, provided that test_usercopy_fixup is installed prior to the run. This enables debugging of modifications made to the usercopy fixup routines, and/or provides a method of verification across system configurations.
Comments are welcome regarding the suitability of this location for these tests, and any other suggestions would also be greatly appreciated.
This was used in conjunction with lib/test_user_copy.c to help verify the following usercopy fixup patches: https://lore.kernel.org/lkml/20200914150958.2200-1-oli.swede@arm.com/
Thanks in advance, Oli
