From 3bca103a1e658d23737d20e1989139d9ca8973bf Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Tue, 7 Oct 2008 20:14:55 +0100 Subject: [ARM] 5295/1: make ZONE_DMA optional Most ARM machines don't need a special "DMA" memory zone, and when configured out, the kernel becomes a bit smaller: | text data bss dec hex filename |3826182 102384 111700 4040266 3da64a vmlinux |3823593 101616 111700 4036909 3d992d vmlinux.nodmazone This is because the system now has only one zone total which effect is to optimize away many conditionals in page allocation paths. So let's configure this zone only on machines that need split zones.
