sparc64: Handle PIO & MEM non-resumable errors.

Browse source

[ Upstream commit 047487241f ]

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.
