[PATCH 0/2] block: Generalize physical entry definition

The block layer code is declared "struct phys_vec" entry which describes
contiguous chunk of physical memory. That definition is useful for all
possible users of DMA physical address-based API.

This series changes NVMe code to support larger chunks of memory by changing
length field from u32 to be size_t, which will be u64 on 64-bits platforms,
and promotes "struct phys_vec" to general place.

nvme-pci: Use size_t for length fields to handle larger sizes
types: move phys_vec definition to common header
