Subject[PATCH] srcu: Remove unused vmlinux srcu linker entries
Date
The SRCU for modules optimization introduced vmlinux linker entries
which is unused since it applies only to the built-in vmlinux. So remove
it to prevent any space usage due to the 8 byte alignment it added.

Tested with SRCU torture_type and rcutorture. Put prints in module
loader to confirm it is able to find and initialize the srcu structures.
