Steve Sistare 7dc4b2fdb2 vfio/type1: fix unmap all on ILP32 ... Some ILP32 architectures support mapping a 32-bit vaddr within a 64-bit iova space. The unmap-all code uses 32-bit SIZE_MAX as an upper bound on the extent of the mappings within iova space, so mappings above 4G cannot be found and unmapped. Use U64_MAX instead, and use u64 for size variables. This also fixes a static analysis bug found by the kernel test robot running smatch for ILP32.
