The sysctl documentation states that the JIT is only available on
x86_64, which is no longer correct.
Update the list to include all architectures that enable HAVE_CBPF_JIT
or HAVE_EBPF_JIT under some configuration.

Thanks for the patch!

Good point, could we actually make that as a bullet list and
differentiate between cBPF and eBPF JITs, so that a user doesn't
need to run git grep HAVE_{E,C}BPF_JIT to figure it out what the
switch enables on the arch used? That would be great.
So for eBPF JITs, we have covered:
* x86_64
* arm64
* ppc64
* sparc64
* mips64
For old cBPF, there is:
* arm
* mips
* ppc
* sparc
Thanks,
Daniel
Values :
0 - disable the JIT (default value)
