I must admit I am not familiar with backport/stable process enough. But personally I think the your suggestion seems more sensible than backporting 4 patches.

Or you can maybe ignore patch 25 and say in patch 24 that among the changes made for the 4.4 codebase, the call arm64_apply_bp_hardening() was moved from post_ttbr_update_workaround as it doesn't exist and placed in check_and_switch_context() as it is its final destination.

Done that and dropped the other two patches.

However, I really don't know what's the best way to proceed according to existing practices. So input from someone else would be welcome.

Lets see if someone comes up and ask me to do something else :)
