From f6a826af05cb9de0de0218f3cd05af203170fd12 Mon Sep 17 00:00:00 2001

Subject: [PATCH 42/65] starfire: Fix dma_addr_t size test for MIPS
Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition. However, 64-bit MIPS configurations
are not detected reliably either.
This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.
