Thank you for your time and for working on this, @samitolvanen! Much appreciated.

How about changing the module flag name to "cfi-normalize-integers" to be more consistent with the naming convention used, and as these could've also possibly happened in regular CFI and with user space programs too (and also possibly with generalize pointers, but we can take a look at it later/separately)?
