From 33f00dcedb0e22cdb156a23632814fc580fcfcf8 Mon Sep 17 00:00:00 2001 From: Ilya Yanok Date: Thu, 12 Feb 2009 13:20:53 +0000 Subject: powerpc: Rework dma-noncoherent to use generic vmalloc layer This patch rewrites consistent dma allocations support to use vmalloc layer to allocate virtual memory space from vmalloc pool and get rid of CONFIG_CONSISTENT_{START,SIZE}. This greatly simplifies the code by effectively removing a custom allocator we had for virtual space.
