sparc64: Handle PIO & MEM non-resumable errors.
[ Upstream commit 047487241ff59374fded8c477f21453681f5995c ]
User processes trying to access an invalid memory address via PIO will
receive a SIGBUS signal instead of causing a panic. Memory errors will
receive a SIGKILL since a SIGBUS may result in a coredump which may
attempt to repeat the faulting access.
