[PATCH] ips fix for large mem 64bit machines 

This patch fixes DMA bugs on x86-64 and ia64 machines.  The driver was
using commands that only support 32bit addresses in places that could
return 64bit addresses.  One place was DMAing off the stack.  The other
place was causing problems on x86-64 machines by calling pci_map()
functions on a region allocated by pci_alloc_consistent().
