17 * Userspace ABI: Register state needed by
19 * -sigcontext (SA_SIGNINFO signal frame)
21 * This is to decouple pt_regs from user-space ABI, to be able to change it
22 * w/o affecting the ABI.
23 * Although the layout (initial padding) is similar to pt_regs to have some
24 * optimizations when copying pt_regs to/from user_regs_struct.
26 * Also, sigcontext only care about the scratch regs as that is what we really
27 * save/restore for signal handling.
