swiotlb: print physical addresses consistently with other parts of kernel
Bjorn Helgaas [Tue, 29 May 2012 22:06:29 +0000 (15:06 -0700)]
Print swiotlb info in a style consistent with the %pR style used elsewhere
in the kernel.  For example:

    -Placing 64MB software IO TLB between ffff88007a662000 - ffff88007e662000
    -software IO TLB at phys 0x7a662000 - 0x7e662000
    +software IO TLB [mem 0x7a662000-0x7e661fff] (64MB) mapped at [ffff88007a662000-ffff88007e661fff]
