Hyper-V Isolation VM may fail to allocate swiotlb bounce buffer due
to there is no enough contiguous memory from 0 to 4G in some cases.
Current swiotlb code allocate bounce buffer in the low end memory.
This patchset adds a switch "swiotlb_alloc_from_low_pages" and it's
set to tr
I think this interface is a little too hacky. In the end all the
non-trusted hypervisor schemes (including the per-device swiotlb one)
can allocate the memory from everywhere and want for force use of
swiotlb. I think we need some kind of proper interface for that instead
of setting all kinds of
