[PATCH tip/core/rcu 4/5] rcu: don't use modular infrastructure in non-modular code

From: Paul E. McKenney
Date: Mon Aug 22 2016 - 11:33:47 EST


From: Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx>

The Kconfig currently controlling compilation of tree.c is:

init/Kconfig:config TREE_RCU
init/Kconfig: bool

...and update.c and sync.c are "obj-y" meaning that none are ever
built as a module by anyone.

Since MODULE_ALIAS is a no-op for non-modular code, we can remove
them from these files.

We leave moduleparam.h behind since the files instantiate some boot
time configuration parameters with module_param() still.
