RPI-LINUX with PREEMT_RT , please make more pair able versions of RPI-LINUX

hi people,

i want you to please make more pair able versions of RPI-LINUX with PREEMT_RT, ideally ALL versions.

----> my problem:
i build PREEMT_RT based on
https://wiki.linuxfoundation.org/realtime/start
and
https://github.com/raspberrypi/linux/commits ----> search repository: Merge remote-tracking branch 'stable/linux-5.10.y' into rpi-5.10.y

examples feb until jul 2021 table:
PREEMT_RT & RPI-LINUX merge with same version
5.10.47 & not exist
5.10.41 & not exist
5.10.35 & exist, and works
5.10.30 & not exist
5.10.27 & exist, and works
5.10.25 & exist, and works
5.10.21 & not exist
....... & ...
there where only some existing compatible in last months
so have to wait until there is a raspberry pi linux with same version than preemt rt, sometimes this takes long time

----> possible problem solution:

bring more RPI-LINUX versions that can be used with PREEMT_RT

example:
check at PREEMT_RT developer the version upcomming will be released, developer for 5.10-rt is Steven Rostedt
if preemt_RT for linux 5.10.comming will be released,
then "merge remote tracking branch for 5.10.comming"

if there is an other !easier! solution dont see then tell please

Start by reviewing the Raspberry Pi Linux commit history, especially merges of stable/linux-5.10.y into rpi-5.10.y, alongside the PREEMPT_RT versions cited in the issue. Determine which additional matching versions are requested and define done as providing more Raspberry Pi Linux versions compatible with PREEMPT_RT, or documenting an easier supported approach.
