Both glibc and the kernel have in6_* macros definitions. Build fails

The default values for nreader and nwriter are apparently not all that
user-friendly, resulting in people doing scalability tests that ran all
runs at large scale. This commit therefore makes both the nreaders and
nwriters module default to the number of CPUs, and adds a comment to
rcuperf.c stating that the number of CPUs should be specified using the
nr_cpus kernel boot parameter. This commit also eliminates the redundant
rcuperf scripting specification of default values for these parameters.

The rcuperf trace-event processing counted every "done" trace event
as a piggyback, which is incorrect because the task that started the
grace period didn't piggyback at all. This commit fixes this problem
by recording the task that started a given grace period and ignoring
that task's "done" record for that grace period.

The rcuperf event-trace processing assumes that expedited grace periods

this now-fallacious assumption from rcuperf's event-trace processing.

The purpose of jitter is to expose concurrency bugs due to invalid
assumptions about forward progress. There is usually little point
in jitter when measuring performance. This commit therefore defaults
jitter off when running rcuperf. You can override this by specifying
the kvm.sh "--jitter" argument -after- the "--torture rcuperf"
argument. No idea why you would want this, but if you do, that is
how you do it.
One example of a conccurrency bug that this jitter might expose is one
in which the developer assumed that a given short region of code would be
guaranteed to execute within some short time limit. Such assumptions are
invalid in virtualized environments because the hupervisor can preempt
the guest OS at any point, even when the guest OS thinks that it has
disabled interrupts.

The 512 megabyte memory size has served quite well, but more memory

Commit 6f1982fedd ("sched/isolation: Handle the nohz_full= parameter")
broke CONFIG_NO_HZ_FULL_ALL=y kernels. This breakage is due to the code
under CONFIG_NO_HZ_FULL_ALL failing to invoke the shiny new housekeeping
functions. This means that rcutorture scenario TREE04 now emits RCU CPU
stall warnings due to the RCU grace-period kthreads not being awakened
at a time of their choosing, or perhaps even not at all:
[ 27.731422] rcu_bh kthread starved for 21001 jiffies! g18446744073709551369 c18446744073709551368 f0x0 RCU_GP_WAIT_FQS(3) ->state=0x402 ->cpu=3

Because no one has complained about CONFIG_NO_HZ_FULL_ALL=y being broken,
I hypothesize that no one is in fact using it, other than rcutorture.
This commit therefore eliminates CONFIG_NO_HZ_FULL_ALL and updates
rcutorture's config files to instead use the nohz_full= kernel parameter
to put the desired CPUs into nohz_full mode.

This should be a general test architecture, and yet allow specific
tests to be done. Introduce a plugin architecture.
An individual test has 4 stages, setup/execute/verify/teardown. Each
plugin gets a chance to run a function at each stage, plus one call
before all the tests are called ("pre" suite) and one after all the
tests are called ("post" suite). In addition, just before each
command is executed, the plugin gets a chance to modify the command
using the "adjust_command" hook. This makes the test suite quite
flexible.
Future patches will take some functionality out of the tdc.py script and
place it in plugins.
To use the plugins, place the implementation in the plugins directory
and run tdc.py. It will notice the plugins and use them.

Four fixes for Power9. The most bizarre being a bug where futexes

early boot (it aliased the kernel mapping). A fix for memory hotplug
when using the Radix MMU, and a fix for live migration of guests using
the Radix MMU.
Two fixes for hotplug on pseries machines. One where we weren't

The current selftests Makefile construct result in cgroup_helpers.c
gets compiled together with all the TEST_GEN_PROGS. And it also result
in invoking the libbpf Makefile two times (tools/lib/bpf).
These issues were introduced in commit 9d1f159419 ("bpf: move
cgroup_helpers from samples/bpf/ to tools/testing/selftesting/bpf/").
The only test program that requires the cgroup helpers is 'test_dev_cgroup'.
Thus, create a make target $(OUTPUT)/test_dev_cgroup that extend[1]
the 'prerequisite' for the 'stem' %-style pattern in ../lib.mk,
for this particular test program.
Reviewers notice the make-rules in tools/testing/selftests/lib.mk
differ from the normal kernel kbuild rules, and it is practical
to use 'make -p' to follow how these 'Implicit/static pattern stem'
gets expanded.
