Hi,
this is wrong:
echo "dtparam=nrf24-spi0-overlay" >> /boot/config.txt
You have nrf24-spi0.dtbo so do the following:
echo "dtparam=nrf24-spi0" >> /boot/config.txt
And do not comment out dtparam=spi=on. Leave it enabled.

Okay uncommented it and changed the dtparam as you indicated. Also moved out /boot/overlays/spi*.dtbo just in case. Same dmesg output (just the kernel taint line). No luck yet!

Is your Log Level set to debug? What does cat /proc/sys/kernel/printk say?

Not sure on the Log Level.
$ cat /proc/sys/kernel/printk
4 4 1 7
Update: I tried insmod again after running the following, but got no extra output in dmesg (or otherwise):
echo 8 | sudo tee /proc/sys/kernel/printk

Weird...
Do you see any spidev in /dev or any nrf* folder in /proc/device-tree/soc/spi@7e204000/ ?

Nope on /dev. Here's proc (grep -i nrf isn't finding anything):

There is something wrong with Device Tree overlay. It is not loaded. If loaded there should be nrf0@0 folder in /proc/device-tree/soc/spi@7e204000/.
Paste /boot/config.txt please.
Are you sure that dtc compiled dts to dtbo?
I use quite new kernel (Linux pi 4.15.0-rc4-v7+ #4 SMP Wed Dec 20 11:20:28 -00 2017 armv7l GNU/Linux) but don't think it should be a problem...

Change dtparam=nrf24-spi0 to dtoverlay=nrf24-spi0 in /boot/config.txt

That did the trick! Thanks a lot!

@mciupak a little bit off-topic, do you have a proven working arm64 mainline kernel config at hand ?
Asking because I saw your message "I use quite new kernel"

Have not tried this, but apparently for Upstream BCM2837 as far as I know defconfig should be fine. Have you tried this?

@mciupak I am sure it needs some tweaks.. I tried it, yes.. it might be fine but I see that it builds all possible platforms... There should be a lot useless stuff.
One more question: how do you usually prepare rpi rootfs ? Do you use your own scripts or any open-source ?
