 *
 * This is to decouple pt_regs from user-space ABI, to be able to change it
 * w/o affecting the ABI.
 * Although the layout (initial padding) is similar to pt_regs to have some
 * optimizations when copying pt_regs to/from user_regs_struct.
 *
 * Also, sigcontext only care about the scratch regs as that is what we really
 * save/restore for signal handling.
