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/crypto/aria_aesni_avx2_glue.c: warning: EXPORT_SYMBOL() is used, but

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

arch/x86/events/intel/core.c: warning: EXPORT_SYMBOL() is not 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.

Thanks for sharing.
FYI, I sent a patch to fix these warnings in Hyper-V related drivers

Some of the files are common to the ones in your patch.
