Results from Linaro’s test farm.
No regressions on arm64, arm, x86_64, and i386.

Tested-by: Linux Kernel Functional Testing <lkft@...aro.org>


NOTE:
Following are the list of intermittent failures.

LTP syscalls msync04 started failing intermittently on 6.3, 6.1 and 5.15 on
arm64 devices which are using NFS mounted rootfs and external mounted drive.
Where as on arm x15 device it is always fails from 6.3.2-rc1, 6.1.28-rc1
and 5.15.111-rc1.

The partition start sector was not specified for /dev/loop0 and it

The number of sectors per track was not specified for /dev/loop0 and
it could not be obtained automatically.  It has been set to 0.
The number of heads was not specified for /dev/loop0 and it could not
be obtained automatically.  It has been set to 0.
To boot from a device, Windows needs the 'partition start sector', the
'sectors per track' and the 'number of heads' to be set.
Windows will not be able to boot from this device.
