tools/virtio/ringtest: Remove bogus definition of BUG_ON()

2019-05-12T17:11:35+00:00

BUG_ON(x) should raise an error if x is true, but assert(x) raises an
error if x is false. Remove this bogus definition of BUG_ON(), which
isn't used anyway.

sg: remove ->sg_magic member

2018-06-29T14:48:06+00:00

This was introduced more than a decade ago when sg chaining was
added, but we never really caught anything with it. The scatterlist
entry size can be critical, since drivers allocate it, so remove
the magic member. Recently it's been triggering allocation stalls
and failures in NVMe.

PCI: remove PCI_DMA_BUS_IS_PHYS

2018-05-07T05:15:41+00:00

This was used by the ide, scsi and networking code in the past to
determine if they should bounce payloads.  Now that the dma mapping
always have to support dma to all physical memory (thanks to swiotlb
for non-iommu systems) there is no need to this crude hack any more.
