Subject: [PATCH 08/14] MIPS: memblock: Simplify DMA contiguous reservation
Date: Thu, 18 Jan 2018 01:23:06 +0300	[thread overview]
Message-ID: <20180117222312.14763-9-fancer.lancer@gmail.com> (raw)
In-Reply-To: <20180117222312.14763-1-fancer.lancer@gmail.com>

CMA reserves it areas in the memblock allocator. Since we aren't
using bootmem anymore, the reservations copying should be discarded.
