Subject: [PATCH] xen: arm: prevent building with CONFIG_EARLY_PRINTK if not a debug build
Date: Wed, 5 Mar 2014 01:02:29 +0000 [thread overview]
Message-ID: <1393981349-6811-1-git-send-email-ian.campbell@citrix.com> (raw)
early printk on ARM is tied to debug being enabled, so error out instead of silently and unexpectedly building without early printk when asked.
