uaccess: Use user_access_ok() in user_access_begin()
Use user_access_ok() instead of access_ok() in user_access_begin()
to validate the access context is user. This also allow us to
use (generic) strncpy_from_user() and strnlen_user() in atomic
state with setting USER_DS and disable pagefaults.

Author: Frederic Weisbecker <frederic(a)kernel.org>

softirq: Allow to soft interrupt vector-specific masked contexts
Remove the old protections that prevented softirqs from interrupting any
softirq-disabled context. Now that we can disable specific vectors on
a given piece of code, we want to be able to soft-interrupt those places
with other vectors.

[page cache] eb797a8ee0: vm-scalability.throughput -16.5% regression
by kernel test robot
Greeting,
FYI, we noticed a -16.5% regression of vm-scalability.throughput due to commit:
commit: eb797a8ee0ab4cd03df556980ce7bf167cadaa50 ("page cache: Rearrange address_space")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 80 threads Skylake with 64G memory
with following parameters:
runtime: 300s
test: small-allocs
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------------------+
| testcase: change | unixbench: unixbench.score 20.9% improvement |
| test machine | 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory |
| test parameters | cpufreq_governor=performance |
| | nr_task=100% |
| | runtime=300s |
| | test=shell8 |
| | ucode=0xb00002e |
+------------------+----------------------------------------------------------------------+
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] 2c83362734: pft.faults_per_sec_per_cpu -41.4% regression
by kernel test robot
Greeting,
FYI, we noticed a -41.4% regression of pft.faults_per_sec_per_cpu due to commit:
commit: 2c83362734dad8e48ccc0710b5cd2436a0323893 ("sched/fair: Consider SD_NUMA when selecting the most idle group to schedule on")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: pft
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 50%
cpufreq_governor: performance
ucode: 0xb00002e
test-description: Pft is the page fault test micro benchmark.
test-url: https://github.com/gormanm/pft
In addition to that, the commit also has significant impact on the following tests:

6d571f333f ("tty/serial: Add a serial port simulator"): BUG: spinlock bad magic on CPU#0, ksoftirqd/0/7
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/cminyard/linux-ipmi serialsim
commit 6d571f333f663ea940d0bdce381bdbed6a202260
Author: Corey Minyard <cminyard(a)mvista.com>
AuthorDate: Thu Feb 28 09:32:32 2019 -0600

tty/serial: Add a serial port simulator
This creates simulated serial ports, both as echo devices and pipe
devices. The driver reasonably approximates the serial port speed
and simulates some modem control lines. It allows error injection
and dirct control of modem control lines.
