rcutorture: Refactor TINY_RCU test cases
The TINY_RCU test cases were first put in place many years ago, and have been incrementally modified rather than being reworked. This commit therefore completes a long-overdue reworking of the TINY_RCU test cases. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Greg KH <gregkh@linuxfoundation.org>

+This document gives a brief rationale for the TINY_RCU test cases.
+
+
+Kconfig Parameters:
+
+CONFIG_DEBUG_LOCK_ALLOC -- Do all three and none of the three.
+CONFIG_PREEMPT_COUNT
+CONFIG_RCU_TRACE
+
+The theory here is that randconfig testing will hit the other six possible
+combinations of these parameters.
+
+
+Kconfig Parameters Ignored:
+
+CONFIG_DEBUG_OBJECTS_RCU_HEAD
+CONFIG_PROVE_RCU
+
+ In common code tested by TREE_RCU test cases.
+
+CONFIG_NO_HZ_FULL_SYSIDLE
+CONFIG_RCU_NOCB_CPU
+CONFIG_RCU_USER_QS
+
+ Meaningless for TINY_RCU.
+
+CONFIG_RCU_STALL_COMMON
+CONFIG_RCU_TORTURE_TEST
+
+ Redundant with CONFIG_RCU_TRACE.
