We currently check the atomic headers at build-time to ensure they haven't been modified directly, and these checks require regenerating the headers in full. As this takes a few seconds, even when parallelized, this is too slow to run for every kernel build. Instead, we can generate a hash of each header as we generate them, which we can cheaply check at build time (~0.16s for all headers). This patch does so, updating headers with their hashes using the new gen-atomics.sh script. As some users apparently build the kernel wihout coreutils, lacking sha1sum, the checks are skipped in this case. Presumably, most developers have a working coreutils installation.
