[RFC 06/23] ARM: LPAE: use phys_addr_t for initrd location and size

From: Cyril Chemparathy
Date: Mon Jul 23 2012 - 21:16:05 EST


From: Vitaly Andrianov <vitalya@xxxxxx>

This patch fixes the initrd setup code to use phys_addr_t instead of assuming
32-bit addressing. Without this we cannot boot on systems where initrd is
located above the 4G physical address limit.
