Subject: [PATCH 12/21] MIPS memblock: Add memblock print outs in debug
Date: Mon, 19 Dec 2016 05:07:37 +0300 [thread overview]
Message-ID: <1482113266-13207-13-git-send-email-fancer.lancer@gmail.com> (raw)
In-Reply-To: <1482113266-13207-1-git-send-email-fancer.lancer@gmail.com>
When debugging it is useful to have a list of all memory regions
added and reserved in the system. Ones are printed right from
memblock if memblock_debug is enabled.
