The patch titled
     Subject: dma-mapping.h: preserve unmap info for CONFIG_DMA_API_DEBUG
has been removed from the -mm tree.  Its filename was
     dma-mappingh-preserve-unmap-info-for-config_dma_api_debug.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: dma-mapping.h: preserve unmap info for CONFIG_DMA_API_DEBUG

When CONFIG_DMA_API_DEBUG is enabled we need to preserve unmapping address
even if "unmap" is a no-op for our architecutre because we need
debug_dma_unmap_page() to correctly cleanup all of the debug bookkeeping. 
Failing to do so results in a false positive warnings about previously
mapped areas never being unmapped.
