arm64: probes: Disable kprobes/uprobes on MOPS instructions
[ Upstream commit c56c599d9002d44f559be3852b371db46adac87c ]
FEAT_MOPS instructions require that all three instructions (prologue,
main and epilogue) appear consecutively in memory. Placing a
kprobe/uprobe on one of them doesn't work as only a single instruction
gets executed out-of-line or simulated. So don't allow placing a probe
on a MOPS instruction.
