	All symbols are reexported reusing the `EXPORT_SYMBOL_GPL` macro
from C. The lists of symbols are generated on the fly.
There are three main sets of symbols to distinguish:
  - The ones from the `core` and `alloc` crates (from the Rust
    standard library). The code is licensed as Apache/MIT.
  - The ones from our abstractions in the `kernel` crate.
  - The helpers (already exported since they are not generated).
We export everything as GPL. This ensures we do not mistakenly
expose GPL kernel symbols/features as non-GPL, even indirectly.
