Ideally I'd like to see > your patches applied *and* lazy mode removed. The latest version of my code (which I should forward-port again to the latest tip bits) simplifies things a lot. It moves all new task handling to switch_fpu_finished(), which is called from do_notify_resume(). At that point we either load the FPU context, or we set CR0.TS. - -- All rights reversed -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJU6yI3AAoJEM553pKExN6DyQEH/13E0T6wsII5L+0W1D0WU4v5 F2SmU74zvCv+RhRl/0npvKRQC3IkZ/peM9h/1PU/r61Y39VhexUxiUZ86afzz4KJ ogPNEs6HZ8UYSji6RPlVsuJJ4vCsZ9GA+27JwKGzLUG1NfniL0qlc93rl+f3ZfFm 5H4bjtcO361Am15yKkFPRl/0PKqRhMDa4tzJGkvvCaJ+k195Ik0a7WXjOlGdIeJA 5Q1D0qaAccXtwfNjqhxIfTBi1LV2a1/jCKF8ktxGJ2+Ywvau9blJnPfD8vUf9JL2 9/le1kyNU3h8B2lU0jIi4a2Y/CcU47heEUy5htmoo6wChQWAy/pR8JaE6++qWqI= =ee/J -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
