BPF trampoline is the critical infrastructure of the bpf

trampoline on RV64. The implementation of bpf trampoline
was closely to x86 and arm64 for future development.
Thank you for working on this! BPF trampoline is the "missing piece"
from getting proper kfunc support.
Unfortunately, I wont be able to do a proper review until next week.
Take your time, it might take several rounds of optimization. Yep, riscv
bpf will look more complete when bpf trampoline and kfunc are supported.
Anyway, have a nice christmas holidays.😄

Happy holidays,
