From mboxrd@z Thu Jan 1 00:00:00 1970 From: r.sricharan@ti.com (R Sricharan) Date: Wed, 12 Sep 2012 11:21:57 +0530 Subject: [PATCH] ARM: OMAP2+: TEMP: Round of the carve out memory requested to section_size Message-ID: <1347429117-10919-1-git-send-email-r.sricharan@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org memblock_steal tries to reserve physical memory during boot. When the requested size is not aligned on the section size then, the remaining memory available for lowmem becomes unaligned on the section boundary. There is a issue with this, which is discussed in the thread below. https://lkml.org/lkml/2012/6/28/112 The final conclusion from the thread seems to be align the memblock_steal calls on the SECTION boundary.
