rcutorture: Refactor TREE_RCU test cases
The TREE_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 TREE_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 TREE_RCU-related test
+cases, a group that includes TREE_PREEMPT_RCU.
+
+
+Kconfig Parameters:
+
+CONFIG_DEBUG_LOCK_ALLOC -- Do three, covering CONFIG_PROVE_LOCKING & not.
+CONFIG_DEBUG_OBJECTS_RCU_HEAD -- Do one.
+CONFIG_HOTPLUG_CPU -- Do half. (Every second.)
+CONFIG_HZ_PERIODIC -- Do one.
+CONFIG_NO_HZ_IDLE -- Do those not otherwise specified. (Groups of two.)
+CONFIG_NO_HZ_FULL -- Do two, one with CONFIG_NO_HZ_FULL_SYSIDLE.
+CONFIG_NO_HZ_FULL_SYSIDLE -- Do one.
+CONFIG_PREEMPT -- Do half. (First three and #8.)
+CONFIG_PROVE_LOCKING -- Do all but two, covering CONFIG_PROVE_RCU and not.
+CONFIG_PROVE_RCU -- Do all but one under CONFIG_PROVE_LOCKING.
+CONFIG_PROVE_RCU_DELAY -- Do one.
+CONFIG_RCU_BOOST -- one of TREE_PREEMPT_RCU.
+CONFIG_RCU_BOOST_PRIO -- set to 2 for _BOOST testing.
+CONFIG_RCU_CPU_STALL_INFO -- do one with and without _VERBOSE.
+CONFIG_RCU_CPU_STALL_VERBOSE -- do one with and without _INFO.
+CONFIG_RCU_FANOUT -- Cover hierarchy as currently, but overlap with others.
+CONFIG_RCU_FANOUT_EXACT -- Do one.
+CONFIG_RCU_FANOUT_LEAF -- Do one non-default.
+CONFIG_RCU_FAST_NO_HZ -- Do one, but not with CONFIG_RCU_NOCB_CPU_ALL.
+CONFIG_RCU_NOCB_CPU -- Do three, see below.
+CONFIG_RCU_NOCB_CPU_ALL -- Do one.
+CONFIG_RCU_NOCB_CPU_NONE -- Do one.
+CONFIG_RCU_NOCB_CPU_ZERO -- Do one.
+CONFIG_RCU_TRACE -- Do half.
+CONFIG_SMP -- Need one !SMP for TREE_PREEMPT_RCU.
+RCU-bh: Do one with PREEMPT and one with !PREEMPT.
+RCU-sched: Do one with PREEMPT but not BOOST.
+
+
+Hierarchy:
+
+TREE01. CONFIG_NR_CPUS=8, CONFIG_RCU_FANOUT=8, CONFIG_RCU_FANOUT_EXACT=n.
+TREE02. CONFIG_NR_CPUS=8, CONFIG_RCU_FANOUT=3, CONFIG_RCU_FANOUT_EXACT=n,
+ CONFIG_RCU_FANOUT_LEAF=3.
+TREE03. CONFIG_NR_CPUS=8, CONFIG_RCU_FANOUT=4, CONFIG_RCU_FANOUT_EXACT=n,

+TREE09. CONFIG_NR_CPUS=1.
+
+
+Kconfig Parameters Ignored:
+
+CONFIG_64BIT
+
+ Used only to check CONFIG_RCU_FANOUT value, inspection suffices.
+
+CONFIG_NO_HZ_FULL_SYSIDLE_SMALL
+
+ Defer until Frederic uses this.
+
+CONFIG_PREEMPT_COUNT
+CONFIG_PREEMPT_RCU
+
+ Redundant with CONFIG_PREEMPT, ignore.
+
+CONFIG_RCU_BOOST_DELAY
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_CPU_STALL_TIMEOUT
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_STALL_COMMON
+
+ Implied by TREE_RCU and TREE_PREEMPT_RCU.
+
+CONFIG_RCU_TORTURE_TEST
+CONFIG_RCU_TORTURE_TEST_RUNNABLE
+
+ Always used in KVM testing.
+
+CONFIG_RCU_USER_QS
+
+ Redundant with CONFIG_NO_HZ_FULL.
+
+CONFIG_TREE_PREEMPT_RCU
+CONFIG_TREE_RCU
+
+ These are controlled by CONFIG_PREEMPT.
