Introduce a helper to store 64-bit immediate on the trampoline stack with a help of a register. Signed-off-by: Menglong Dong <[email protected]>

Implement BPF_TRACE_FSESSION support in the RISC-V trampoline JIT. The logic here is similar to what we did in x86_64. In order to simply the logic, we factor out the function invoke_bpf() for fentry and fexit. Signed-off-by: Menglong Dong <[email protected]>
Now that the RISC-V trampoline JIT supports BPF_TRACE_FSESSION, run the fsession selftest on riscv64 as well as x86_64. Signed-off-by: Menglong Dong <[email protected]>
