Subject: [PATCH 3/5] powerpc: mem_init should call memblock_is_reserved with phys_addr_t
Date: Tue, 28 Jun 2011 14:54:46 -0500 [thread overview]
Message-ID: <13092910702553-git-send-email-beckyb@kernel.crashing.org> (raw)
In-Reply-To: <13092910103675-git-send-email-beckyb@kernel.crashing.org>
From: Becky Bruce <beckyb@kernel.crashing.org>
This has been broken for a while but hasn't been an issue until
now because nobody was reserving regions at high addresses.
