In arch/sparc64/kernel/traps.c, data_access_exception() is defined to receive 3 parameters, (and uses all three of them). In arch/sparc64/kernel/unaligned.c it is only passed a single parameter.
This is causing me difficulty when handling segfault signals. On most Linux platforms I have access to the siginfo_t.si_addr isn't populated at all anyway, and I use the ucontext_t third parameter given to the handler. Under sparc64 though, the third parameter doesn't point to anything that I can discern, and due to the aforementioned three versus one parameter issue, the value of si_addr in siginfo_t is incorrect as well.
This issue appears to be present in both 2.4, and 2.6.
