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;
