There seems to be some debugger infrastructure present already for kgdb,
but I assume this cannot be used.
Anyway - trap 0x7d is a debugger trap in sparc32.
If CONFIG_KGDB is not defined then 0x7d is just a regular BAD_TRAP.
For sparc64 trap 0x7d is something different.
I did not conclude what was the right choice for neither.
