Subject: [PATCH 2/2] arch/x86: Fix sparse warning symbol not declared

This patch adds function declaration in order to quiet sparse symbol
not declared warning.

Signed-off-by: Tobin C. Harding <me@...in.cc>
---

Unsure why adding declaration quiets sparse. This may not be the
correct solution. Only testing done is building and booting kernel.
Since 'purgatory' is called from assembler and does not need forward
declaration the only advantage to this patch seems to be to save the
next newbie from investigating the sparse warning.
