Merge branch 'linus' into x86/boot, to resolve conflict
There's a new conflict with Linus's upstream tree, because in the following merge conflict resolution in <asm/coco.h>: 38b334fc767e Merge tag 'x86_sev_for_v6.9_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Linus has resolved the conflicting placement of 'cc_mask' better than the original commit: 1c811d403afd x86/sev: Fix position dependent variable references in startup code ... which was also done by an internal merge resolution: 2e5fc4786b7a Merge branch 'x86/sev' into x86/boot, to resolve conflicts and to pick up dependent tree But Linus is right in 38b334fc767e, the 'cc_mask' declaration is sufficient within the #ifdef CONFIG_ARCH_HAS_CC_PLATFORM block. So instead of forcing Linus to do the same resolution again, merge in Linus's tree and follow his conflict resolution. Conflicts: arch/x86/include/asm/coco.h Signed-off-by: Ingo Molnar <mingo@kernel.org>
