For the 32-bit syscall interface, 64-bit arguments (loff_t) are passed via a pair of 32-bit registers. These register pairs end up in consecutive stack slots, which matches the C ABI for 64-bit arguments. But when accessing the registers directly from pt_regs, the wrapper needs to manually reassemble the 64-bit value. These wrappers already exist for 32-bit compat, so make them available to 32-bit native in preparation for enabling pt_regs-based syscalls.
