Boot-tested under QEMU for Rust x86_64, arm64 and riscv64; built-tested
for loongarch64:

Tested-by: Miguel Ojeda <ojeda@kernel.org>

arm32 also builds fine.

On arm64, I am seeing:

    net/sched/act_mirred.c:451:43: warning: variable 'm_eaction' is uninitialized when used here [-Wuninitialized]
      451 |         is_redirect = tcf_mirred_is_act_redirect(m_eaction);
          |                                                  ^~~~~~~~~
    net/sched/act_mirred.c:429:18: note: initialize the variable 'm_eaction' to silence this warning
      429 |         int i, m_eaction;
          |                         ^
          |                          = 0

due to commit a01fbdecc3a2 ("net/sched: act_mirred: Fix return code in
early mirred redirect error paths") here.

And that one seems to be missing at least the assignment to the variable
that happened in commit a005fa5d7502 ("net/sched: act_mirred: Fix
blockcast recursion bypass leading to stack overflow").

I hope this helps!
