[PATCH v3 09/17] ARM: LPAE: use phys_addr_t for initrd location and size

From: Vitaly Andrianov <redacted> 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.
