| * Userspace ABI: Register state needed by | |
| * -ptrace (gdbserver) | |
| * -sigcontext (SA_SIGNINFO signal frame) | |
| * | |
| * This is to decouple pt_regs from user-space ABI, to be able to change it | |
| * w/o affecting the ABI. | |
| * | |
| * The intermediate pad,pad2 are relics of initial layout based on pt_regs | |
| * for optimizations when copying pt_regs to/from user_regs_struct. | |
| * We no longer need them, but can't be changed as they are part of ABI now. | |
| * | |
| * Also, sigcontext only care about the scratch regs as that is what we really | |
| * save/restore for signal handling. However gdb also uses the same struct | |
| * hence callee regs need to be in there too. | |
