[PATCH 0/9] dma_debug: add debug_dma_mapping_error support to architectures that support DMA_DEBUG_API

[Shuah Khan <shuah.khan@hp.com>]

An earlier patch added dma mapping error debug feature to dma_debug
infrastructure. References:

https://lkml.org/lkml/2012/10/8/296
https://lkml.org/lkml/2012/11/3/219

The following series of patches adds the call to debug_dma_mapping_error() to
architecture specific dma_mapping_error() interfaces on the following
architectures that support CONFIG_DMA_API_DEBUG.

arm64
c6x
ia64
microblaze
mips
powerpc
sh
sparc
tile

arm - Change is already in Marek's dma-mapping tree[1] 
https://patchwork.kernel.org/patch/1625601/

microblaze - Change is already in linux-next. Including it for completeness
linux-next commit f229605441030bcd315c21d97b25889d63ed0130

x86 - done in the first patch that added the feature.

ARM64: dma_debug: add debug_dma_mapping_error support
c6x: dma_debug: add debug_dma_mapping_error support
ia64: dma_debug: add debug_dma_mapping_error support
microblaze: dma-mapping: support debug_dma_mapping_error
mips: dma_debug: add debug_dma_mapping_error support
powerpc: dma_debug: add debug_dma_mapping_error support
sh: dma_debug: add debug_dma_mapping_error support
sparc: dma_debug: add debug_dma_mapping_error support
tile: dma_debug: add debug_dma_mapping_error support
