From: "Naveen N. Rao" <naveen.n.rao@xxxxxxxxxxxxxxxxxx>
commit 844e3be47693f92a108cb1fb3b0606bf25e9c7a6 upstream.
Backport required due to rename of HAVE_BPF_JIT to HAVE_CBPF_JIT
upstream - mpe.
Classic BPF JIT was never ported completely to work on little endian
powerpc. However, it can be enabled and will crash the system when used.
As such, disable use of BPF JIT on ppc64le.
Fixes: 7c105b63bd98 ("powerpc: Add CONFIG_CPU_LITTLE_ENDIAN kernel config option.")
