Sorry, whatever I did with git send-email appears to have eaten my cover letter on this series - the text was: This series adds support for E0PD. We enable E0PD unconditionally where present on systems where all the CPUs in the system support E0PD and change to not enabling KPTI by default on systems where we have enabled E0PD. v3: Make E0PD a system wide feature. --cYtjc4pxslFTELvY Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl2nNO0ACgkQJNaLcl1U h9CkqAf9EjmLyMyUsCtM9lCaEbYp6BGaygMbS28yWbz0PCLeHTIUXac3SexvAU9o m8e11FS4sATVsnv9WUxMY594YlTB2H5HiKMXlpoIsZdTwDPaVrgVePjO7BYt+/R5 R3ivVUUIPz6yPtkUqxUU5MLVOJnCuLKn4TNVjq1kHI5YaB8TJJjvuBK2gSAgRYVF jtwk7c6DgWRUN3XSqPt1xyPNJaYk2VIDDP3y621Bp5bk9l05+hcc1eEQn0c1ZRyL CnLaFs7SSMnhPBatGFlspWDUVAtiSMoX7yThq54JQZo0byiTq52KaEMjt51n5nHv Idu4XIaqKfvT3KH9T/0NmS5bMZguVw== =Kbxj -----END PGP SIGNATURE----- --cYtjc4pxslFTELvY-- --===============5565312346921337506== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============5565312346921337506==--
