    Subject[PATCH 0/2] x86/FPU: FPU sanitization for in-kernel use
    Date
    From: Borislav Petkov <bp@suse.de>

    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.
