Subject: [PATCH] target/alpha: Remove fallback to ev67 cpu class
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
'ev67' CPU class will be returned to match everything, which makes
no sense as mentioned in the comments. Remove the logic to fall
back to 'ev67' CPU class to match everything.
