Add a kprobes on ftrace testcase. The testcase verifies that
- enabling and disabling function tracing works on a function which
already contains a dynamic kprobe
- adding and removing a dynamic kprobe works on a function which is
already enabled for function tracing

Running ftracetests on a box that mounted debugfs in two locations
made the ftracetests fail. This is because the tests uses a grep
of debugfs from the /proc/mounts file to find the debugfs mount
point, and then appends "/tracing" to that string to get the tracing
directory.
If the debugfs directory is mounted twice, then that grep will return
two answers and appending "/tracing" to a string with two lines will
not work.
Use "head -1" to only take the first mount point found.

Add two selftest scripts which tests kprobe-tracer as the startup
selftest does.
These test cases are testing that the kprobe_event can accept a
kprobe event with $stack related arguments and a kretprobe event
with $retval argument.

Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/
UNTESTED/UNSUPPORTED) as result codes. These are used for the
results that test case is expected to fail or unsupported
feature (by config).
To return these result code, this introduces exit_unresolved,
exit_untested, exit_unsupported and exit_xfail functions,
which use real-time signals to notify the result code to
ftracetest.
This also set "errexit" option for the testcases, so that
the tests don't need to exit explicitly.
Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL,
its test log including executed commands is shown on console
and main logfile as below.

ftracetest is a collection of testcase shell-scripts for ftrace.
To avoid regressions of ftrace, these testcases check correct
ftrace behaviors. If someone would like to add any features on
ftrace, the patch series should have at least one testcase for
checking the new behavior.

Pull namespace updates from Eric Biederman:
"This is a bunch of small changes built against 3.16-rc6. The most
significant change for users is the first patch which makes setns
drmatically faster by removing unneded rcu handling.
The next chunk of changes are so that "mount -o remount,.." will not
allow the user namespace root to drop flags on a mount set by the
system wide root. Aks this forces read-only mounts to stay read-only,
no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec
mounts to stay no exec and it prevents unprivileged users from messing
with a mounts atime settings. I have included my test case as the
last patch in this series so people performing backports can verify
this change works correctly.
The next change fixes a bug in NFS that was discovered while auditing
nsproxy users for the first optimization. Today you can oops the
kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever
with pid namespaces. I rebased and fixed the build of the
!CONFIG_NFS_FS case yesterday when a build bot caught my typo. Given
that no one to my knowledge bases anything on my tree fixing the typo
in place seems more responsible that requiring a typo-fix to be
backported as well.
The last change is a small semantic cleanup introducing
/proc/thread-self and pointing /proc/mounts and /proc/net at it. This
prevents several kinds of problemantic corner cases. It is a
user-visible change so it has a minute chance of causing regressions
so the change to /proc/mounts and /proc/net are individual one line
commits that can be trivially reverted. Unfortunately I lost and
could not find the email of the original reporter so he is not
credited. From at least one perspective this change to /proc/net is a
refgression fix to allow pthread /proc/net uses that were broken by
the introduction of the network namespace"

Setting SEAL_WRITE is not possible if there're pending GUP users. This
commit adds selftests for memfd+sealing that use FUSE to create pending
page-references. FUSE is very helpful here in that it allows us to delay
direct-IO operations for an arbitrary amount of time. This way, we can
force the kernel to pin pages and then run our normal selftests.

On IBM powerpc where multiple page size value are supported, current
ppc64 and ppc64el distro don't define the PAGE_SIZE variable in
/usr/include as this is a dynamic value retrieved by the getpagesize()
or sysconf() defined in unistd.h. The PAGE_SIZE variable sounds defined
when only one value is supported by the kernel.
As such, when the PAGE_SIZE definition doesn't exist system should
retrieve the dynamic value.

Pull powerpc updates from Ben Herrenschmidt:
"This is the powerpc new goodies for 3.17. The short story:
The biggest bit is Michael removing all of pre-POWER4 processor
support from the 64-bit kernel. POWER3 and rs64. This gets rid of a
ton of old cruft that has been bitrotting in a long while. It was
broken for quite a few versions already and nobody noticed. Nobody
uses those machines anymore. While at it, he cleaned up a bunch of
old dusty cabinets, getting rid of a skeletton or two.
Then, we have some base VFIO support for KVM, which allows assigning
of PCI devices to KVM guests, support for large 64-bit BARs on
"powernv" platforms, support for HMI (Hardware Management Interrupts)
on those same platforms, some sparse-vmemmap improvements (for memory
hotplug),
There is the usual batch of Freescale embedded updates (summary in the
merge commit) and fixes here or there, I think that's it for the
highlights"

Kenton Varda <kenton@sandstorm.io> discovered that by remounting a
read-only bind mount read-only in a user namespace the
MNT_LOCK_READONLY bit would be cleared, allowing an unprivileged user
to the remount a read-only mount read-write.
Upon review of the code in remount it was discovered that the code allowed
nosuid, noexec, and nodev to be cleared. It was also discovered that
the code was allowing the per mount atime flags to be changed.
The first naive patch to fix these issues contained the flaw that using
default atime settings when remounting a filesystem could be disallowed.
To avoid this problems in the future add tests to ensure unprivileged
remounts are succeeding and failing at the appropriate times.

There is at least one bug in core_busy_loop(), we use r0, but it's
not in the clobber list. We were getting away with this it seems but
that was luck.
It's also fishy to be touching the stack, even if we do it below the
stack pointer. It seems we get away with it, but looking at the
generated code that may just be luck.
So move it into assembler, do all the stack handling by hand. We create
a stack frame to save the non-volatiles in, so we can muck around with
them.

Currently we ignore errors from our sub Makefiles. We inherited that
from the top-level selftests Makefile which aims to build and run as
many tests as possible and damn the torpedoes.
For the powerpc tests we'd instead like any errors to fail the build, so
we can automatically catch build failures.
We can achieve the best of both worlds by using -k, which tells make to
keep building when it hits an error, but still reports the error.

On some systems, hot-plug tests could hang forever waiting for cpu and
memory to be ready to be offlined. A special hot-plug target is created
to run full range of hot-plug tests. In default mode, hot-plug tests run
in safe mode with a limited scope. In limited mode, cpu-hotplug test is
run on a single cpu as opposed to all hotplug capable cpus, and memory
hotplug test is run on 2% of hotplug capable memory instead of 10%. In
addition to the above change, cpu-hotplug is chnged to change processor
affinity to cpu 0 so it doesn't impact itself while the test runs.

on-off-test is a bash script and invoked from /bin/sh
This results in the following error:
./on-off-test.sh: 9: [: !=: unexpected operator
Changed Makefile to use bash instead.

The CONFIG_PROVE_RCU_DELAY Kconfig parameter doesn't appear to be very
effective at finding race conditions, so this commit removes it.

The test fails in the middle when it is not run as root while accessing
/proc/sys/kernel/msg_next_id. Changed it to check for root at the
beginning of the test and exit if not root.

on-off-test uses "$UID != 0" to test for root, but $UID is a construct
specific to bash. Using /bin/sh that isn't bash results in the
following error (due to the "$UID" part expanding to nothing):
./on-off-test.sh: 9: [: !=: unexpected operator
Change Makefile to use bash instead.

Currently the post-processing complains about the lack of rcutorture
output when --buildonly is set and also emits misleading messages about
kernels being started and finishing. This commit suppresses these
complaints and messages.

The CFcommon file must now be present, which makes using the current
scripts against old kernel versions cumbersome. This commit therefore
makes the CFcommon file be optional, so that old kernel versions can be
used with current torture scripts.

Pull more powerpc updates from Ben Herrenschmidt:
"Here are the remaining bits I was mentioning earlier. Mostly bug
fixes and new selftests from Michael (yay !). He also removed the WSP
platform and A2 core support which were dead before release, so less
clutter.
One little "feature" I snuck in is the doorbell IPI support for
non-virtualized P8 which speeds up IPIs significantly between threads
of a core"
