Daniel Kiper abc93f8eb6 efi: Use early_mem*() instead of early_io*() ... Use early_mem*() instead of early_io*() because all mapped EFI regions are memory (usually RAM but they could also be ROM, EPROM, EEPROM, flash, etc.) not I/O regions. Additionally, I/O family calls do not work correctly under Xen in our case. early_ioremap() skips the PFN to MFN conversion when building the PTE. Using it for memory will attempt to map the wrong machine frame. However, all artificial EFI structures created under Xen live in dom0 memory and should be mapped/unmapped using early_mem*() family calls which map domain memory.
