+/* 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.
