powerpc/bpf: Emit stf barrier instruction sequences for BPF_NOSPEC
[ Upstream commit b7540d62509453263604a155bf2d5f0ed450cba2 ]
Emit similar instruction sequences to commit a048a07d7f4535
("powerpc/64s: Add support for a store forwarding barrier at kernel
entry/exit") when encountering BPF_NOSPEC.
Mitigations are enabled depending on what the firmware advertises. In
particular, we do not gate these mitigations based on current settings,
just like in x86. Due to this, we don't need to take any action if
mitigations are enabled or disabled at runtime.
