powerpc/8xx: Force VIRT_IMMR_BASE to be a positive number
The asm-offsets mechanism generates signed numbers, even if the input value is explicitly unsigned. This causes a problem with older binutils (e.g. 2.23), which sign-extend a negative number when @h is applied. Thus, this instruction: cmpli cr0, r11, VIRT_IMMR_BASE@h resulted in this: Error: operand out of range (0xfffffff0 is not between 0x00000000 and 0x0000ffff) By casting to a larger type, we can force the output to be expressed as a positive number.
