The memconsole driver is not using proper accessors for __iomem.  Switch
to memremap to fix this issue, and this also prepares the driver for the
removal of ioremap_cache.

Could you maintain the existing style of the broken line alignment in this file?

  	if (!memconsole) {
-		pr_err("memconsole: ioremap_cache failed\n");
+		pr_err("memconsole: memremap failed\n");
  		return -ENOMEM;
  	}
  	ret = memory_read_from_buffer(buf, count, &pos, memconsole,
  				      memconsole_length);

   Here's an example...

-	iounmap(memconsole);
+	memunmap(memconsole);
  	return ret;
  }

MBR, Sergei
