Hey Linus,

Please pull a tiny fix for v5.0-rc2:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-5.0

This fixes an issue with GPU cards not working anymore with the DMA
mapping work Christopher did - as the SWIOTLB is initialized first
and then free-ed (as IOMMU is available) but we forgot to clear our
start and end entries which are used and BOOM.

Thank you!
