-/* Most of the fields are self-explanatory.  'sr0' is the next
-   instruction to execute, from SRR0, which may have some relationship
-   with the instruction that caused the exception.  'r3*' is the value
-   that will be returned in register 3 when the current system call
-   returns.  'sr1' is SRR1, bits 16-31 of which are copied from the MSR:
-
-   16 - External interrupt enable
-   17 - Privilege level (1=user, 0=supervisor)
-   18 - FP available
-   19 - Machine check enable (if clear, processor locks up on machine check)
-   20 - FP exception mode bit 0 (FP exceptions recoverable)
-   21 - Single-step trace enable
-   22 - Branch trace enable
-   23 - FP exception mode bit 1
-   25 - exception prefix (if set, exceptions are taken from 0xFFFnnnnn,
-        otherwise from 0x000nnnnn).
-   26 - Instruction address translation enabled.
-   27 - Data address translation enabled.
-   30 - Exception is recoverable (otherwise, don't try to return).
-   31 - Little-endian mode enable.
-
-   'Trap' is the address of the exception:
-
-   00200 - Machine check exception (memory parity error, for instance)
-   00300 - Data access exception (memory not mapped, see dsisr for why)
-   00400 - Instruction access exception (memory not mapped)
-   00500 - External interrupt
-   00600 - Alignment exception (see dsisr for more information)
-   00700 - Program exception (illegal/trap instruction, FP exception)
-   00800 - FP unavailable (should not be seen by user code)
-   00900 - Decrementer exception (for instance, SIGALRM)
-   00A00 - I/O controller interface exception
-   00C00 - System call exception (for instance, kill(3)).
-   00E00 - FP assist exception (optional FP instructions, etc.)
-
-   'dar' is the memory location, for traps 00300, 00400, 00600, 00A00.
-   'dsisr' has the following bits under trap 00300:
-   0 - direct-store error exception
-   1 - no page table entry for page
-   4 - memory access not permitted
-   5 - trying to access I/O controller space or using lwarx/stwcx on
-       non-write-cached memory
-   6 - access was store
-   9 - data access breakpoint hit
-   10 - segment table search failed to find translation (64-bit ppcs only)
-   11 - I/O controller instruction not permitted
-   For trap 00400, the same bits are set in SRR1 instead.
-   For trap 00600, bits 12-31 of the DSISR set to allow emulation of
-   the instruction without actually having to read it from memory.
