The rsvp classifier has served us well for about a quarter of a century but has
has not been getting much maintenance attention due to lack of known users.

8c710f7525 net/sched: Retire tcindex classifier
The tcindex classifier has served us well for about a quarter of a century
but has not been getting much TLC due to lack of known users. Most recently
it has become easy prey to syzkaller. For this reason, we are retiring it.

40cab44b90 net/sched: fix retpoline wrapper compilation on configs without tc filters
Rudi reports a compilation failure on x86_64 when CONFIG_NET_CLS or
CONFIG_NET_CLS_ACT is not set but CONFIG_RETPOLINE is set.
A misplaced '#endif' was causing the issue.

7f0e810220 net/sched: add retpoline wrapper for tc
On kernels using retpoline as a spectrev2 mitigation,
optimize actions and filters that are compiled as built-ins into a direct call.

On subsequent patches we expose the classifiers and actions functions
and wire up the wrapper into tc.
