We used bpf_prog_pack to aggregate bpf programs into huge page to relieve the iTLB pressure on the system. We can apply it to bpf trampoline, as Song had been implemented it in core and x86 [0]. This patch is going to use bpf_prog_pack to RV64 bpf trampoline. Since Song and Puranjay have done a lot of work for bpf_prog_pack on RV64, implementing this function will be easy.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
