5.11-1 [1] today. Unfortunately this kernel doesn't boot on my FSL P5040 
board [2] and in a virtual e5500 QEMU machine [3].

Hello Denis,

I have bisected [5] and d0e3fc69d00d1f50d22d6b6acfc555ccda80ad1e 
(powerpc/vdso: Provide __kernel_clock_gettime64() on vdso32) [6] is the 
first bad commit.

I was able to revert this bad commit and after a new compiling, the 
kernel boots without any problems.

Thanks,
Christian
