#     Merge branch 'stable/for-linus-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
#     
#     Pull swiotlb fix from Konrad Rzeszutek Wilk:
#      "One single fix in here: under Xen the DMA32 heap (in the hypervisor)
#       would end up looking like swiss cheese.
#     
#       The reason being that for every coherent DMA allocation we didn't do
#       the proper hypercall to tell Xen to return the page back to the DMA32
#       heap. End result was (eventually) no DMA32 space if you (for example)
#       continously unloaded and loaded modules"
#     
#     * 'stable/for-linus-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb:
#       xen-swiotlb: fix the check condition for xen_swiotlb_free_coherent
