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.

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.
