- * (1) that the members of all these structures are carefully aligned to permit
- * usage of STD/STDF instructions
- *
- * (2) if you change these structures, you must change the code in
- * arch/frvnommu/kernel/{break.S,entry.S,switch_to.S,gdb-stub.c}
- *
- *
- * the kernel stack space block looks like this:
- *
- * +0x2000 +----------------------
- * | union {
- * | struct frv_frame0 {
- * | struct user_context {
- * | struct user_int_regs
- * | struct user_fpmedia_regs
- * | }
- * | struct frv_debug_regs
- * | }
- * | struct pt_regs [user exception]
- * | }
- * +---------------------- <-- __kernel_frame0_ptr (maybe GR28)
- * |
- * | kernel stack
- * |
- * |......................
- * | struct pt_regs [kernel exception]
- * |...................... <-- __kernel_frame0_ptr (maybe GR28)
- * |
- * | kernel stack
- * |
- * |...................... <-- stack pointer (GR1)
- * |
- * | unused stack space
- * |
- * +----------------------
- * | struct thread_info
- * +0x0000 +---------------------- <-- __current_thread_info (GR15);
- *
- * note that GR28 points to the current exception frame
