and commit 7d95680d64ac8e836c ("scripts/misc-check:
check unnecessary #include <linux/export.h> when W=1"),
we get some build warnings with W=1,such as:
arch/x86/coco/sev/core.c: warning: EXPORT_SYMBOL() is used, but #include
<linux/export.h> is missing

arch/x86/kvm/hyperv.c: warning: EXPORT_SYMBOL() is used, but #include

arch/x86/kernel/crash.c: warning: EXPORT_SYMBOL() is not used, but #include
<linux/export.h> is present
arch/x86/kernel/devicetree.c: warning: EXPORT_SYMBOL() is not used, but #include
<linux/export.h> is present
so fix these build warnings for x86.

Your patch is looking a little bit strange, as the list of modified files
is located between the patch hunks, followed by another "Signed-off-by:".
