Recent times kvmalloc() begun widely be used in kernel.
Some of such memory allocations have to be freed after
rcu grace period, and this patchset introduces a generic
primitive for doing this.
Actually, everything is made in [1/2]. Patch [2/2] is just
added to make new kvfree_rcu() have the first user.
The patch [1/2] transforms kfree_rcu(), its sub definitions
and its sub functions into kvfree_rcu() form. The most
significant change is in __rcu_reclaim(), where kvfree()
is used instead of kfree(). Since kvfree() is able to
have a deal with memory allocated via kmalloc(), vmalloc()
and kvmalloc(); kfree_rcu() and vfree_rcu() may simply
be defined through this new kvfree_rcu().
