I guess I can try. The commit message states:

Merge: c77f54a9bcec a1cf1fd62ae7 562163595a91 018d6711c26e 6cc401be1648

Is there a way extract out each of those?

Manually looking at the diff with
git diff e996c7e01892ac18ec0db447294d4f591c325efe~  e996c7e01892ac18ec0db447294d4f591c325efe 
I guess that means the following:

--- a/drivers/acpi/x86/utils.c
+++ b/drivers/acpi/x86/utils.c

 }
 

Thanks,
