Subject: [PATCH] x86,boot: standardize strcmp()
Date: Mon, 16 Mar 2015 21:07:47 +0530	[thread overview]
Message-ID: <1426520267-1803-1-git-send-email-arjun024@gmail.com> (raw)

strcmp() is always expected to return 0 when args are
same, <0 when arg1 is lesser and >0 otherwise.
Previously strcmp("a","b") returned 1. Now it gives -1.
