Some explicit memory barriers in the page table code are not necessary,
either because:

(a) The barrier follows a non-relaxed MMIO access that already performs
a read or write memory barrier.

(b) The barrier follows DMA API calls for which the device-visible
effects of IOMMU programming are guaranteed to be flushed to the IOMMU
prior to the call returning, and doesn't need to sync with normal memory
access.

Use of readl() is deprecated; readl_relaxed() with appropriate memory
barriers is preferred.  Switch to relaxed reads and writes for better
performance as well.  Memory barriers required for I/O vs. normal
memory access on Apex devices have already been explicitly coded in the
page table routines.

gasket_alloc_dev can retrieve the device name from the parent parameter,
