Don't know - I've always taken ioremap_nocache() as a mis-understanding of what ioremap() itself is supposed to do. Indeed, if you look at IO-mapping.txt, ioremap_nocache() is not mentioned, and it's pretty clear that ioremap() is what is intended to be used to map MMIO. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
