[Question] diff between debian kernel and stable kernel

[Masahiro Yamada <masahiroy@kernel.org>]

Hello, Debian kernel team,

I have a question about the code diff
between the orig.tar.xz and the upstream
stable kernel.




[1] orig.tar.xz of the debian kernel

  $ apt source linux

As of writing, I get

  linux_5.10.28.orig.tar.xz


[2] stable kernel from kernel.org

I can download the same version of
the stable kernel from kernel.org, like this:

$ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.28.tar.xz




I just expected [1] and [2] would be the same,
but actually some files are missing in the
debian one.


I extracted [1] and [2], and compared the contents.


$ diff -r -u  deb/linux-5.10.28/  korg/linux-5.10.28/
Only in korg/linux-5.10.28/arch/powerpc/platforms/8xx: micropatch.c

I guess there are some reasons why those files were deleted from the
debian kernel.

What is the story behind this?
