This patch became commit 5f58c97099f2 ("ARM: at91: move debug-macro.S
into the common space") in today's linux-next (ie, next-20150120). I
noticed because a script I use to check linux-next spotted a problem in
it.

There's no Kconfig symbol DEBUG_AT91_UART in linux-next. So this select
is currently a nop. Why was it added?

Ditto.
