This breaks the x86 clang allmodconfig build as I presume those
involved know by now:

../drivers/hv/vmbus_drv.c:2082:29: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
static u64 vmbus_dma_mask = DMA_BIT_MASK(64);
                            ^~~~~~~~~~~~~~~~
../include/linux/dma-mapping.h:76:54: note: expanded from macro 'DMA_BIT_MASK'
#define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
                                                     ^ ~~~
