* Switch to contigmalloc in the Hyper-V codeAndrew Turner2023-06-061-6/+0
| | | | | | | | | | | | | | | In the Hyper-V drivers we need to allocate buffers shared between the host and guest. This memory has been allocated with bus_dma, however it doesn't use this correctly, e.g. it is missing calls to bus_dmamap_sync. Along with this on arm64 we need this memory to be mapped with the correct memory type that bus_dma may not use. Switch to contigmalloc to allocate this memory as this will correctly allocate cacheable memory.
