Subject: [PATCH] arm64: pi: add early_map_kernel prototype

From: Arnd Bergmann <[email protected]>

The newly added function only has a caller from assembler code, so it
works without an extern prototype, but we get a warning if it's missing:

arch/arm64/kernel/pi/map_kernel.c:224:24: error: no previous prototype for 'early_map_kernel' [-Werror=missing-prototypes]

Fixes: 478ea5689054 ("arm64: head: Move early kernel mapping routines into C code")

Applied to arm64 (for-next/lpa2-stage1), thanks!

[1/1] arm64: pi: add early_map_kernel prototype
https://git.kernel.org/arm64/c/8d05e7b6eec9

We are still checking whether the recent CKI reports are caused by this
branch, so I may drop it before the merging window (fully or partially).
