This is a step in the right direction for another reason: clearly the

This symlinks bpf_testmod into the main source, so it can be built-in

To be clear, no changes to the existing selftests are required: this

Both BPF_JIT and KPROBES depend on CONFIG_MODULES, but only require
module_alloc() itself, which can be easily separated into a standalone
allocator for executable kernel memory.
Thomas Gleixner sent a patch to do that for x86 as part of a larger
series a couple years ago:

No BPF code has to change, except in struct_ops (for module refs).
This conflicts with bpf-next because of this (relevant) series:

Hello all,
This patchset makes it possible to use bpftrace with kprobes on kernels
built without loadable module support.
On a Raspberry Pi 4b, this saves about 700KB of memory where BPF is
needed but loadable module support is not. These two kernels had
identical configurations, except CONFIG_MO
This patch enables support for DYNAMIC_FTRACE_WITH_CALL_OPS on RISC-V.
This allows each ftrace callsite to provide an ftrace_ops to the common
ftrace trampoline, allowing each callsite to invoke distinct tracer
functions without the need to fall back to list processing or to
allocate custom trampol

Instead of manually extracting certain bits from registers with binary
ANDs and shifts, the FIELD_GET macro can be used. With this in mind, the
*_SHIFT macros can be dropped.
