Linux next 20220419 boot failed on arm architecture qemu_arm and BeagleBoard x15 device.

Unfortunately, the vmlinux.xz file I downloaded from the link below seems to be different from the one that produced the crash, given that the LR address of c04cfeb8 does not seem to correspond with handle_mm_fault+0x60c/0xed0.
Can you please double check the artifacts?
Commit "mm: check against orig_pte for finish_fault()" introduced this, i.e. on yesterdays next reverting a066bab3c0eb made a i.MX6 boot again.
Thanks for the pointers, I have reverted the suggested commit and boot pass now.

A fix is discussed here: https://lore.kernel.org/all/YliNP7ADcdc4Puvs@xz-m1.local/
