Are you actually using XIP in something other than QEMU? The fact that some of the blamed fixes are over 18 months old suggests that you are not actively using XIP builds of the mainline kernel. There is a desire to remove XIP support (among other things), so if you do actually have a use case for it, speak up. --xSuSDjmgmyqSuJoL Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZXhepgAKCRB4tDGHoIJi 0jcqAQCByPwOCiYOjlVouNbs/zKoh371UnfHZ1BeZJiI/QsL0QD/SOI4PuK+QXAU +SeC5o/vGm6VXMQZICUQ9Qdax13aTA4= =UatY -----END PGP SIGNATURE----- --xSuSDjmgmyqSuJoL--
