[BUG] The latest sof/main fails when playing back and recording through nocodec port2 on PTL RVP

[jsarha]

Describe the bug
Firmware crashes when trying following command (any 44.1kHz wav should do):
aplay -Dhw:0,2 -d 10 wav/sweep_32b2c44kHz.wav & arecord -Dhw:0,2 -f S16_LE -c 2 -r 32000 -d 10 -vvv -i recording.wav

To Reproduce
Build the latest sof/main ce13360 for PTL and copy the firmware and modules etc. to a nocodec PTL RVP. Any recent enough Linux version and recent sof-ptl-nocodec.tplg should do. Reboot the RVP and when the new FW is loaded run:
aplay -Dhw:0,2 -d 10 wav/sweep_32b2c44kHz.wav & arecord -Dhw:0,2 -f S16_LE -c 2 -r 32000 -d 10 -vvv -i recording.wav

Reproduction Rate
10/10

Expected behavior
The both commands in the commandline should succeed.

I bisected this and the first bad commit is:

llext: map modules for userspace LL

When loading and linking LLEXT modules map them automatically for the
LL memory domain, unless they belong to the DP domain.

I also reverted the commit from current sof/main and that also fixes the issue.
