Due to missing headers, when including "tb-jmp-cache.h" we might get:
accel/tcg/tb-jmp-cache.h:21:21: error: field ‘rcu’ has incomplete type
21 | struct rcu_head rcu;
| ^~~
accel/tcg/tb-jmp-cache.h:24:9: error: unknown type name ‘vaddr’
24 | vaddr pc;
| ^~~~~
Add the missing "qemu/rcu.h" and "exec/cpu-common.h" headers.
