Paul Chaignon e240f26a7f bpf, mips: Limit to 33 tail calls ... [ Upstream commit e49e6f6db04e915dccb494ae10fa14888fea6f89 ] All BPF JIT compilers except RISC-V's and MIPS' enforce a 33-tail calls limit at runtime. In addition, a test was recently added, in tailcalls2, to check this limit. This patch updates the tail call limit in MIPS' JIT compiler to allow 33 tail calls. Fixes: b6bd53f9c4 ("MIPS: Add missing file for eBPF JIT.")
