PATCH 1/1 Change default from CLASSIC_RCU to TREE_RCU (testing only)
This patchset changes the default RCU implementation from CONFIG_CLASSIC_RCU to CONFIG_TREE_RCU. This affects kernel/Kconfig.preempt as well as a large number of the arch-specific defconfig files.
PATCH 1/1 Set the default RCU to be rcutree

ouch!
There's a much more shrewd method to achieve the same, via 2 lines total patch:
Change the name of CONFIG_CLASSIC_RCU to something else such as CONFIG_FLAT_RCU. That does all the magic and more: all configs will default to tree-rcu - not just defconfigs! Agreed?

Lazy or not, your approach is much better than what I was doing. ;-)
Two patches in subsequent emails: the first gets rid of a duplicate RCU_CPU_STALL_DETECTOR config declaration (noticed in this exercise -- one each from the CLASSIC_RCU and TREE_RCU stall detectors), and the second changes the default to TREE_RCU as you suggest.
Thanx, Paul
PATCH 1/1 Remove redundant RCU_CPU_STALL_DETECTOR declaration
This patch removes the redundant RCU_CPU_STALL_DETECTOR Kconfig parameter. We got one from the classic RCU detector and the other from the hierarchical RCU detector, this patch merges them.
This patch is suitable for inclusion.

OK. But don't I also need "select FLAT_RCU" so that all of the defconfig files containing "CLASSIC_RCU" do the right thing? If I try that, "make defconfig" complains as follows:
init/Kconfig:941:error: found recursive dependency: FLAT_RCU -> CLASSIC_RCU -> FLAT_RCU -> <choice>
So unless I am missing a laziness opportunity in here somewhere, it seems to me that I need to either (1) change all the arch files so that what is now "CLASSIC_RCU" instead becomes "FLAT_RCU" or (2) change all in-code references to "CLASSIC_RCU" to instead reference "FLAT_RCU".
Unless there is some other way out, option #2 seems to me to be the lazier of the two, which is represented by the earlier patch. This patch, updated to handle the RCU choice moving to init/Kconfig, appears below. One consequence of this change is that RCU moves from the "Processor type and features" menu to the top level is xconfig and friends.
Which might be why Sam is suggesting HAVE_PREEMPT, which could allow it to stay where it is?
If so, another alternative would be to add kernel/Kconfig.rcu, and add it to all the arch/*/Kconfig files. Then it would still appear in the "Processor type and features" menu, but would also be available to all arches.
Thoughts?

PATCH 1/1 v2 Make hierarchical RCU be the default
This patch makes the new TREE_RCU be the default, pointing the old CLASSIC_RCU Kconfig symbol at it and introducing a new FLAT_RCU symbol to allow the old version to be selected. It also introduces the kernel config parameter RCU_READ_PREEMPT_DISABLE, which allows debug code in pagemap.h to operate in TREE_RCU as it did in FLAT_RCU.
The approach is to place the RCU-specific configs in a new file named kernel/Kconfig.rcu, which is sourced from kernel/Kconfig.preempt, making this change transparent to all architectures that source kernel/Kconfig.preempt. The remaining five architectures (alpha, frv, h8300, m68k, and sparc) have been modified to select CLASSIC_RCU in their arch Kconfigs and to source kernel/Kconfig.rcu. The only difference that these five arches will see is the RCU configs at the very end of the config list. These five architectures were tested by directly invoking qconf on the corresponding Kconfig file, and the results looked correct. I do not have the corresponding hardware for any sort of real testing.
The resulting patch is relatively small, and directly touches a minimum number of architectures.
This patch is -not- yet suitable for inclusion, only for testing in -tip, -next, and the like. If all goes well, it might be appropriate for 2.6.29.

below is the fix for another small buglet that hits architectures that do not include
kernel/Kconfig.preempt.
What is needed to let all architectures include Kconfig.preempt? We should not advertise preemption if not supported, but we could do this by a simple Kconfig symbol:
config HAVE_PREEMPT
bool
And let all architectures that supports preemption do:
config "ARCH"
select HAVE_PREEMPT
But maybe there is a simpler solution

below is the fix for another small buglet that hits architectures that do not include
kernel/Kconfig.preempt.What is needed to let all architectures include
Kconfig.preempt? We should not advertise preemption if not supported, but we could do this by a simpleKconfigsymbol:config
HAVE_PREEMPT
bool
Quoted 6 lines
And let all architectures that supports preemption do:
config "ARCH"
selectHAVE_PREEMPTBut maybe there is a simpler solution
The idea being to make things like PREEMPT then depend on HAVE_PREEMPT?
Seems reasonable to me, but I cannot claim to understand the relationship of Kconfig and the various arches very well.
Thanx, Paul

Yes - exactly.
So an arch can say that is includes support for preemption using the following Kconfig snippet:
config X86
select HAVE_PREEMPT
And then in the spot where we have a prompt we do:
config PREEMPT
bool "Do you want preemption?"
depends on HAVE_PREEMPT
Thne we will only present this option to the user for the architectures where it has indicated preemption support by selecting HAVE_PREEMPT.
It is on purpose that HAVE_PREEMPT is a single boolean with no prompt or anything so we do not hit any of the pitfalls of using select.
We use a similar pattern in many places today.

Since a preemptive kernel is not supported by all architectures, there has to be per arch ways to express this - i.e. i think your solution is the cleanest.

Hmmm... Now that you mention it, I made a similar error some time back. You would think that I would learn. :-/
Thank you, and Merry Christmas!!!
