There are already issues with using the xxx_kernel variants of the page table functions for IO mappings on later architectures (caused by speculative loads hitting IO regions.) This code needs to change slightly so that we have xxx_io versions of pte_alloc and friends. (It also means that we need an ioremap region and a separate vmalloc region on ARM...) -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
