Subject: cleanup vmap usage in the dma-mapping layer
Date: Fri, 30 Aug 2019 08:29:20 +0200	[thread overview]
Message-ID: <20190830062924.21714-1-hch@lst.de> (raw)

Hi all,

the common DMA remapping code uses the vmalloc/vmap code to create
page table entries for DMA mappings.  This series lifts the currently
arm specific VM_* flag for that into common code, and also exposes
it to userspace in procfs to better understand the mappings.
