- * This struct defines the way the registers are stored on the

- *
- * this should only contain volatile regs
- * since we can keep non-volatile in the thread_struct
- * should set this up when only volatiles are saved
- * by intr code.
- *
- * Since this is going on the stack, *CARE MUST BE TAKEN* to insure
- * that the overall structure is a multiple of 16 bytes in length.

- * Note that the offsets of the fields in this struct correspond with
- * the PT_* values below. This simplifies arch/powerpc/kernel/ptrace.c.
