The reason for the ENTRY is to get it aligned, not because it's
globally visible. It doesn't have any fallthroughs, and some cpu's
care more than others.
See commit b06babac45e1 ("Add proper alignment to ENTRY").
Not that I'm sure the alignment matters all that much, but I thought
I'd point it out. Removing the ENTRY() does a lot more than just
remote the .globl.
