[PATCH] pci_alloc_consistent memory conservation

[Brian King]

Currently pci_alloc_consistent calls __get_free_pages to allocate
memory. This results in a lot of wasted memory if people call
pci_alloc_consistent a lot for odd sized allocations (which is what I
wanted to do). The attached patch changes pci_alloc_consistent to use
kmalloc and pci_map_single to accomplish the same function, with the
added benefit of kmalloc to reduce the amount of wasted memory.

Comments?
