Use acpi_os_map_memory() instead of ioremap() in einj driver
ioremap() has become more picky and is now spitting out console messages like: ioremap error for 0xbddbd000-0xbddbe000, requested 0x10, got 0x0 when loading the einj driver. What we are trying to so here is map a couple of data structures that the EINJ table points to. Perhaps acpi_os_map_memory() is a better tool for this? Most importantly it works, but as a side benefit it maps the structures into kernel virtual space so we can access them with normal C memory dereferences, so instead of using: writel(param1, &v5param->apicid); we can use the more natural: v5param->apicid = param1; Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
