Subject: [PATCH 14/15] arm64: move early_brk64 prototype to header

From: Arnd Bergmann <arnd@...db.de>

The prototype used for calling early_brk64() is in the file that calls
it, which is the wrong place, as it is not included for the definition:

arch/arm64/kernel/traps.c:1100:12: error: no previous prototype for 'early_brk64' [-Werror=missing-prototypes]

Move it to an appropriate header instead.
