[PATCH] large-dma_addr_t-PAE-only.patch

From: William Lee Irwin III <wli@holomorphy.com>

I was just looking over this and noticed 2.4.x makes u64 dma_addr_t
conditional on CONFIG_HIGHMEM64G where 2.5.x uses CONFIG_HIGHMEM.  It's
clearly not necessary on CONFIG_HIGHMEM4G, hence this obvious patch.
