Subject: cleanup the dma_pgprot handling
Date: Fri, 16 Aug 2019 09:07:48 +0200 [thread overview]
Message-ID: <20190816070754.15653-1-hch@lst.de> (raw)
Hi all,
this series replaced the arch_dma_mmap_pgprot hooks with the
simpler pgprot_dmacoherent as used by the arm code already and
cleans up various bits around that area.
I'd still like to hear a confirmation from the mips folks how
the write combibe attribute can or can't work with the KSEG1
uncached segment.
