Thank you Daniel! Will investigate those.
OK, thank you :). Notice that I did those tests on x86_64. It seems you are testing on arm, so there may be some differences.
I just checked these tests on 4.4.133 (on x86_64): fcntl35: PASS fcntl35_64: PASS select04: PASS
I am currently investigating other tests that are failing as well. They are not regressions, just some patches have not been backported yet.
Thanks, Daniel
Meanwhile, Greg, I referred to:
time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting
Since we're not using this type of clock on arm64's 4.4 kernel vdso functions. This commit's description calls attention for it to be responsible for fixing kselftest flacking tests, we wouldn't get that on 4.4 according to bellow:
stable-rc-linux-4.14.y dbb236c1ceb6 arm64/vdso: Fix nsec handling for CLOCK_MONOTONIC_RAW 49eea433b326 arm64: Add support for CLOCK_MONOTONIC_RAW in clock_gettime() vDSO 82e88ff1ea94 hrtimer: Revert CLOCK_MONOTONIC_RAW support 9c808765e88e hrtimer: Add support for CLOCK_MONOTONIC_RAW
stable-rc-linux-4.16.y dbb236c1ceb6 arm64/vdso: Fix nsec handling for CLOCK_MONOTONIC_RAW 49eea433b326 arm64: Add support for CLOCK_MONOTONIC_RAW in clock_gettime() vDSO 82e88ff1ea94 hrtimer: Revert CLOCK_MONOTONIC_RAW support 9c808765e88e hrtimer: Add support for CLOCK_MONOTONIC_RAW
stable-rc-linux-4.4.y
<none>
stable-rc-linux-4.9.y 99f66b5182a4 arm64/vdso: Fix nsec handling for CLOCK_MONOTONIC_RAW 49eea433b326 arm64: Add support for CLOCK_MONOTONIC_RAW in clock_gettime() vDSO 82e88ff1ea94 hrtimer: Revert CLOCK_MONOTONIC_RAW support 9c808765e88e hrtimer: Add support for CLOCK_MONOTONIC_RAW
Yet, the second fix was backported to all (including 4.4.y):
stable-rc-linux-4.14.y 3d88d56c5873 time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting stable-rc-linux-4.16.y 3d88d56c5873 time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting stable-rc-linux-4.4.y 7c8bd6e07430 time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting stable-rc-linux-4.9.y a53bfdda06ac time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting
Not sure you want to keep it in 4.4, thought it was worth mentioning it.
Cheers.

Hello Rafael,
The tests fcntl35 and fcntl35_64 should have go from FAIL to PASS. https://www.spinics.net/lists/stable/msg239475.html
Looking at
https://qa-reports.linaro.org/lkft/linux-stable-rc-4.4-oe/build/v4.4.132-93-... 3d7cdea9/testrun/228569/suite/ltp-syscalls-tests/tests/
I see that these two tests (and other important tests as well) are being SKIPPED.
By the way, I see that select04 FAILS in your case. But in my setup, select04 was
working fine (x86_64) in 4.4.132. I will confirm that it still works in 4.4.133
Thanks, Daniel Sangorrin

No regressions (compared to build v4.4.132-71-g180635995c36)
It should have gotten better, as there was a fix in here for at least 2 LTP tests that we previously were not passing. I don't know why you all were not reporting that in the past, it took someone else randomly deciding to run LTP to report it to me...
Why did an improvement in results not show up?
Are you referring to the CLOCK_MONOTONIC_RAW fix for the arm64 vDSO ? I think that CLOCK_MONOTONIC_RAW in VDSO wasn't backported to 4.4.y (commit 49eea433b326 in mainline) so this "fix" is changing the timekeeping sauce (that would fix MONOTONIC RAW) but not for 4.4.y in ARM64. Needs review though :\
