rcu: Uninline rcu_lock_acquire() and rcu_lock_release()
Uninline rcu_lock_acquire() and rcu_lock_release() to shrink .text/data.
The difference in "size vmlinux" looks good,
with CONFIG_DEBUG_LOCK_ALLOC
- 5377829 3018320 14757888 23154037
+ 5352229 3010160 14757888 23120277
33760 bytes saved.
with CONFIG_DEBUG_LOCK_ALLOC + CONFIG_PROVE_RCU + CONFIG_TREE_RCU_TRACE
- 5678315 3027032 14757888 23463235
+ 5578795 3026776 14757888 23363459
saves 99776 bytes.
However, this obviously means that the "warn once" logic is moved from
the current callers of rcu_lockdep_assert(rcu_is_watching()) to update.c.
Also, with this patch we do not bother to report which function abused
rcu_is_watching(), this should be clear from dump_stack().
