Sadly, no. Not unless you exactly match their compiler version. And it
looks like you don't, because the line numbers make no sense.

For example, this is the thing I would expect shows exactly *which* of
the roundup_pow_of_two()'s it is that causes it, but:

> [    4.510096] amdgpu_vm_adjust_size.cold (drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c:2083 (discriminator 1))

that amdgpu_vm.c:2083 line doesn't match anything, and isn't even
inside amdgpu_vm_adjust_size() - or something it would be inlining -
at all.

So I'm afraid it would have to be done at the KernelCI/LKFT side.
