Subject: [PATCH v4 1/2] x86/purgatory: Fix sparse warning, symbol not declared
Date: Mon, 20 Feb 2017 10:12:35 +1100
Message-ID: <1487545956-2547-2-git-send-email-me@tobin.cc> (raw)
In-Reply-To: <1487545956-2547-1-git-send-email-me@tobin.cc>

Sparse emits several 'symbol not declared' warnings for various
functions and variables.

Add static keyword to functions and variables which have file scope
only.
