kernel: powerpc/kprobes: Fix null pointer reference in arch_prepare_kprobe()

A flaw was found in the Linux kernel in archpreparekprobe: where certain error conditions are not properly validated before dereferencing a pointer. Under specific circumstances, this can result in a NULL pointer dereference in kernel space. If triggered, the kernel may generate an oops or panic,...
