The code should check for the size of the phys_initrd_size rather than phys_devtree_size before calling memblock_reserve().If initrd is not passed from the Device Tree the parameters phys_initrd_start, and phys_initrd_size are zeros.The kernel complaints with a BUG if the arguments passed to memblock_reserve are zeroes.
