This series adds RISC-V JIT support for the timed may_goto loop bound. Patch 1 implements arch_bpf_timed_may_goto() and enables bpf_jit_supports_timed_may_goto() so the verifier uses the timed expansion path.
Patch 2 enables the verifier_may_goto_1, stream_cond_break, and may_goto_interaction fastcall tests on riscv64. Tested on riscv64 QEMU (rva23s64): may_goto programs load and JIT correctly, and the 250ms timeout path works as expected.
