-Subject: [PATCH] mips: bpf: Enable eBPF JITs
-
-This patch enables the new eBPF JITs for 32-bit and 64-bit MIPS. It also
-disables the old cBPF JIT to so cBPF programs are converted to use the
-new JIT.
-
-Workarounds for R4000 CPU errata are not implemented by the JIT, so the
-JIT is disabled if any of those workarounds are configured.
-
