ARM: 5988/1: pgprot_dmacoherent() for non-mmu builds
Commit 26a26d329688ab018e068b412b03d43d7c299f0a ("dma-mapping: switch
ARMv7 DMA mappings to retain 'memory' attribute") added a new macro,
pgprot_dmacoherent(), to correctly map DMA memory. The non-mmu pgtable
support code also needs to implement this macro, otherwise when
compiling you get:
CC arch/arm/mm/dma-mapping.o
arch/arm/mm/dma-mapping.c: In function 'dma_alloc_coherent':
arch/arm/mm/dma-mapping.c:320: error: implicit declaration of function 'pgprot_dmacoherent'
arch/arm/mm/dma-mapping.c:320: error: 'pgprot_kernel' undeclared (first use in this function)
arch/arm/mm/dma-mapping.c:320: error: (Each undeclared identifier is reported only once
arch/arm/mm/dma-mapping.c:320: error: for each function it appears in.)
