virtio: virtio_has_iommu_quirk -> virtio_has_dma_quirk

2020-08-03T20:11:42Z

Now that the corresponding feature bit has been renamed, rename the quirk too - it's about special ways to do DMA, not necessarily about the IOMMU. Signed-off-by: Michael S. Tsirkin

virtio: VIRTIO_F_IOMMU_PLATFORM -> VIRTIO_F_ACCESS_PLATFORM

2020-08-03T20:11:42Z

Rename the bit to match latest virtio spec. Add a compat macro to avoid breaking existing userspace. Signed-off-by: Michael S. Tsirkin Reviewed-by: David Hildenbrand

compiler: Remove uninitialized_var() macro

2020-07-16T19:35:31Z

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. As recommended[2] by[3] Linus[4], remove the macro. With the recent change to disable -Wmaybe-uninitialized in v5.7 in commit 78a5255ffb6a ("Stop the ad-hoc games with -Wno-maybe-initialized"), this is likely the best time to make this treewide change.
