162 set_memory_[uc|wc|wt] and set_memory_wb should be used in pairs, where driver
163 will first make a region uc, wc or wt and switch it back to wb after use.
168 Drivers should use ioremap_[uc|wc] to access PCI BARs with [uc|wc] access
171 Drivers should use set_memory_[uc|wc|wt] to set access type for RAM ranges.
