Subject: [PATCH 10/38] powerpc: Add comment explaining the purpose of setup_kdump_trampoline()

From: Benjamin Herrenschmidt <[email-masked]>
Date: Mon, 27 Jun 2016 21:29:08 +1000

Anything in early_setup() needs to be justified to be there, in
this case, we need the trampolines before we can take exceptions
and thus before we turn on the MMU.

Also remove a pretty meaningless and misplaced debug message
