[GIT PULL] Kselftest fixes update for Linux 6.6-rc7

[Shuah Khan <skhan@xxxxxxxxxxxxxxxxxxx>]

Hi Linus,

Please pull the following Kselftest fixes update for Linux 6.6-rc7.

This Kselftest update for Linux 6.6-rc7 consists of one single fix
to assert check in user_events abi_test to properly check bit value
on Big Endian architectures. The current code treats the bit values
as Little Endian and the check fails on Big Endian.

diff is attached.

thanks,
-- Shuah
