From f563f0d3fc27e841ecc6dde1685811f7709e9adf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fabiano=20Fid=C3=AAncio?= Date: Fri, 1 Nov 2024 14:13:44 +0100 Subject: [PATCH 1/3] versions: Update kernel to v6.12.8 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are lots of configs removed from latest kernel. Update them here for convenience of next kernel upgrade. Remove CONFIG_SECURITY_SELINUX_CHECKREQPROT_VALUE [1] Remove CONFIG_IP_NF_TARGET_CLUSTERIP [2] Remove CONFIG_NET_SCH_CBQ [3] Remove CONFIG_AUTOFS4_FS [4] Remove CONFIG_EMBEDDED [5] Remove CONFIG_ARCH_RANDOM & CONFIG_RANDOM_TRUST_CPU [6] [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6&id=a7e4676e8e2cb158a4d24123de778087955e1b36 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6&id=9db5d918e2c07fa09fab18bc7addf3408da0c76f [3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6&id=051d442098421c28c7951625652f61b1e15c4bd5 [4] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6&id=1f2190d6b7112d22d3f8dfeca16a2f6a2f51444e [5] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6&id=ef815d2cba782e96b9aad9483523d474ed41c62a [6] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.2&id=b9b01a5625b5a9e9d96d14d4a813a54e8a124f4b Apart from the removals, CONFIG_CPU_MITIGATIONS is now a dependency for CONFIG_RETPOLINE (which has been renamed to CONFIG_MITIGATION_RETPOLINE) and CONFIG_PAGE_TABLE_ISOLATION (which has been renamed to CONFIG_MITIGATION_PAGE_TABLE_ISOLATION). I've added that to the whitelist because we still build older versions of the kernel that do not have that dependency.
