liang.huang a04d67e7dc arch/risc-v: fix fault handler misattributing kernel faults to user tasks 
riscv_fault_handler() only checked the task type and SYSCALL flag, so a
fault taken inside an interrupt handler (running in kernel mode) was
blamed on the user task that happened to be interrupted and killed with
SIGSEGV, hiding the real kernel bug.  Use the STATUS_PPP bit of the trap
frame to tell whether the fault originated from user mode: only then is
it safe to kill the task.
