From: Borislav Petkov <b...@suse.de> Ok,
here's v2 with build fixes and other review comments addressed. Thx. Changelog: ---------- v1: == Hi all, here's a proper submission of the work started by Petteri. I think I've addressed all the feedback so far. I've added the preparation work for the test to run, to a script run_test_fpu.sh which does some basic checks, loads the module and runs the test for 1000 times on all CPUs, by default. Thought this is a sane default, feel free to prove me wrong and I'll change it. Thx.
