Subject: fix x86 swiotlb regression
Date: Mon, 9 Apr 2018 11:15:16 +0200 [thread overview]
Message-ID: <20180409091517.6619-1-hch@lst.de> (raw)
Hi all,
this patch fixes a regression in the x86 swiotlb conversion. This mostly
happend because swiotlb_dma_support does the wrong thing (and did so for
a long time) and we switched x86 to use it.
There are a few others users of swiotlb_dma_supported that also look
rather broken, but I'll take care of those for the next merge window.
