Or I can build it into the fs/pstore layer. If the record size looks too
small[*], loop writing multiple records (starting with the tail of the buffer,
so that if the persistent store fills up, we are sure to have the stack
back trace and register dump).

with a large number of registers (like ia64) might need more space
than those with fewer registers.
