Struct pt_regs is not ABI, and can (and has) changed on x86. It's not suitable for a checkpoint structure because it only contains the registers that the kernel trashes, not all usermode registers (on i386, it leaves out %gs, for example). asm-x86/ptrace-abi.h does define stuff that's fixed in stone; it expresses it in terms of a register array, with constants defining what element is which register.
