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
