void __iomem *
ioremap_nocache(resource_size_t offset,
unsigned long size);

DESCRIPTION¶
ioremap performs a platform specific sequence of operations to make bus memory CPU accessible via the readb/readw/readl/writeb/ writew/writel functions and the other mmio helpers. The returned address is not guaranteed to be usable directly as a virtual address. If the area you are trying to map is a PCI BAR you should have a look at pci_iomap.AUTHORS¶
