| 19 | * -sigcontext (SA_SIGNINFO signal frame) | |
| 20 | * | |
| 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. | |
| 25 | * | |
| 26 | * Also, sigcontext only care about the scratch regs as that is what we really | |
| 27 | * save/restore for signal handling. | |
