Thanks a lot!
AP is now revived *with* v5.4 built with gcc-8.4.0.
Hauke already did all the hevy debugging work. I assumed that if
http://git.kernel.org/linus/9012d011660ea5cf2a623e1de207a2bc0ca6936d
broke this, then a simple quickfix would be to disable
CONFIG_OPTIMIZE_INLINING
But looking at that dsp stuff, I noticed that there was a pair of
suspicious-looking inlined (or not after v5.4...) functions. So without
understanding much of this, I just tested once with the attached patch.
And it boots:

Now, I could be completely wrong here. This could very well be some

Proper analysis from somebody with a clue is appreciated :-)
Note that the kernel grows a lot with these two functions inlined.
