Subject: [PATCH] ARCH OMAP : enable ARCH_HAS_HOLES_MEMORYMODEL for OMAP
Date: Thu,  7 Jan 2010 18:00:08 +0530	[thread overview]
Message-ID: <1262867408-9895-1-git-send-email-srk@ti.com> (raw)

From: Sriram <srk@ti.com>

OMAP platforms(like OMAP3530) include DSP or other co-processors
for media acceleration. when carving out memory for the
accelerators we can end up creating a hole in the memory map
of sort:
<kernel memory><hole(memory for accelerator)><kernel memory>

To handle such a memory configuration ARCH_HAS_HOLES_MEMORYMODEL
has to be enabled. For further information refer discussion at:
http://www.mail-archive.com/linux-omap@vger.kernl.org/msg15262.html.
