The fixed version works for the following cases with gcc-12:
1. no BTF, no IBT;
2. with BTF and CONFIG_MODULE_ALLOW_BTF_MISMATCH, no IBT;
3. with BTF and CONFIG_MODULE_ALLOW_BTF_MISMATCH, with IBT;
There is still some issue with BTF, so we need
CONFIG_MODULE_ALLOW_BTF_MISMATCH here.
But it appears to be mostly working.
OTOH, there are still some issues with LLVM ("symbol 'xxx' already
defined", etc.).
Thanks,
