v4l2-dev/ioctl: require non-zero device_caps, verify sane querycap results
Now that all V4L2 drivers set device_caps in struct video_device, we can add
a check for this to ensure all future drivers fill this in.
Also verify that when the querycap ioctl is called the driver didn't mess
with the device_caps value and that capabilities is a superset of device_caps.

lib: introduce test_meminit module
Add tests for heap and pagealloc initialization. These can be used to
check init_on_alloc and init_on_free implementations as well as other
approaches to initialization.
Expected test output in the case the kernel provides heap initialization
(e.g. when running with either init_on_alloc=1 or init_on_free=1):
test_meminit: all 10 tests in test_pages passed
test_meminit: all 40 tests in test_kvmalloc passed
test_meminit: all 60 tests in test_kmemcache passed
test_meminit: all 10 tests in test_rcu_persistent passed
test_meminit: all 120 tests passed!

a0335bd901 ("mm: assert that mmap_sem is held over .."): WARNING: CPU: 0 PID: 152 at include/linux/mmu_notifier.h:296 unmap_vmas
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.infradead.org/users/hch/misc.git mmu-notifier-cleanup
commit a0335bd9017dd91a934284f569c028e4a10bce45
Author: Christoph Hellwig <hch(a)lst.de>
AuthorDate: Tue Jul 23 10:23:09 2019 +0200
Commit: Christoph Hellwig <hch(a)lst.de>
CommitDate: Tue Jul 23 10:26:52 2019 +0200
mm: assert that mmap_sem is held over invalidate_range_{start,end}
The notifiers rely on the fact that mmap_sem is held, so add lockdep
annotations to assert that this is actually true.

by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
commit a0d14b8909de55139b8702fe0c7e80b69763dcfb
Author: Peter Zijlstra <peterz(a)infradead.org>
AuthorDate: Thu Jul 11 13:40:59 2019 +0200
Commit: Thomas Gleixner <tglx(a)linutronix.de>
CommitDate: Wed Jul 17 23:17:38 2019 +0200
x86/mm, tracing: Fix CR2 corruption
Despite the current efforts to read CR2 before tracing happens there still
exist a number of possible holes:
idtentry page_fault do_page_fault has_error_code=1
call error_entry
TRACE_IRQS_OFF
call trace_hardirqs_off*
#PF // modifies CR2
CALL_enter_from_user_mode
__context_tracking_exit()
trace_user_exit(0)
#PF // modifies CR2
call do_page_fault
address = read_cr2(); /* whoopsie */
And similar for i386.
Fix it by pulling the CR2 read into the entry code, before any of that
stuff gets a chance to run and ruin things.

mm: assert that mmap_sem is held over invalidate_range_{start,end}
The notifiers rely on the fact that mmap_sem is held, so add lockdep
annotations to assert that this is actually true.

[gpio] f69e00bd21: unixbench.score -24.2% regression
by kernel test robot
Greeting,
FYI, we noticed a -24.2% regression of unixbench.score due to commit:
commit: f69e00bd21aa6a1961c521b6eb199137fcb8a76a ("gpio: mmio: Support two direction registers")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: unixbench
on test machine: 16 threads Intel(R) Xeon(R) CPU D-1541 @ 2.10GHz with 8G memory
with following parameters:
runtime: 300s
nr_task: 30%
test: context1
cpufreq_governor: performance
ucode: 0x7000017
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:

[x86/modules] f2c65fb322: will-it-scale.per_process_ops -2.9% regression
by kernel test robot
Greeting,
FYI, we noticed a -2.9% regression of will-it-scale.per_process_ops due to commit:
commit: f2c65fb3221adc6b73b0549fc7ba892022db9797 ("x86/modules: Avoid breaking W^X while loading modules")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads Intel(R) Xeon(R) CPU @ 2.20GHz with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: poll1
cpufreq_governor: performance
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml

[sched/fair] b3e5e9a1dd: hackbench.throughput 38.7% improvement
by kernel test robot
Greeting,
FYI, we noticed a 38.7% improvement of hackbench.throughput due to commit:
commit: b3e5e9a1ddb6f4122985b1164dd9186be788e138 ("sched/fair: use load instead of runnable load")
https://git.linaro.org/people/vincent.guittot/kernel.git sched-rework-load_balance
in testcase: hackbench
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
nr_threads: 100%
mode: threads
ipc: pipe
cpufreq_governor: performance
ucode: 0xb8
test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler.
test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sc...
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------------------+
| testcase: change | hackbench: hackbench.throughput 47.5% improvement |
| test machine | 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory |
| test parameters | cpufreq_governor=performance |
| | ipc=pipe |
| | mode=process |
| | nr_threads=50% |
| | ucode=0xb000036 |
+------------------+----------------------------------------------------------------------+
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:

[blackhole_dev] 509e56b37c: kernel_selftests.net.test_blackhole_dev.sh.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: 509e56b37cc32c9b5fc2be585c25d1e60d6a1d73 ("blackhole_dev: add a selftest")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master
in testcase: kernel_selftests
with following parameters:
group: kselftests-02
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 8G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen(a)intel.com>
# selftests: net: test_blackhole_dev.sh
# test_blackhole_dev: [FAIL]
not ok 13 selftests: net: test_blackhole_dev.sh
To reproduce:
# build kernel
cd linux
