Subject: tip/x86/dma fix for arc and s390 (at least)
Date: Wed, 28 Mar 2018 15:35:34 +0200	[thread overview]
Message-ID: <20180328133535.17302-1-hch@lst.de> (raw)

Hi all,

this restores previous __GFP_ZERO passthrough behavior for now as arc and
s390 rely on it.  Needs more work to sort out the API mess in the long run.
