12 By "answered the questions" can I assume this to mean `make oldconfig`?

18 This looks fine.

23 This also looks fine

30 For anyone to give you a useful answer, we would need more detailed
31 information about your specific issue - for example:
32
33 - - how far through the boot process does the "broken" kernel get?
34 - - Are there any error messages or stack traces?
35 - - Is there any display at all?
36 - - What is the kernel cmdline used to boot the kernel?
37 - - Do you use an initramfs?
38
39 As for the kernel diff below, there are obviously a few options changed
40 between the kernels, but without more information about your hardware and an
41 idea of what is actually happening, it's difficult to tell if any are the
42 cause of your issue.
