Linus Torvalds fd6f57bfda Kbuild updates for v5.17
- Add new kconfig target 'make mod2noconfig', which will be useful to
    speed up the build and test iteration.
 
  - Raise the minimum supported version of LLVM to 11.0.0
 
  - Refactor certs/Makefile
 
  - Change the format of include/config/auto.conf to stop double-quoting
    string type CONFIG options.
 
  - Fix ARCH=sh builds in dash
 
  - Separate compression macros for general purposes (cmd_bzip2 etc.) and
    the ones for decompressors (cmd_bzip2_with_size etc.)
 
  - Misc Makefile cleanups

When you move, remove or rename generated files, you probably also update

.gitignore and cleaning rules in the Makefile. This is the right thing

to do. However, people usually do 'git pull', 'git bisect', etc. without

running 'make clean'. Then, the stale generated files are left over, often

causing build issues.

Also, 'git status' shows such stale build artifacts as untracked files.

What is worse, some people send a wrong patch to get them back to .gitignore

without checking the commit history.

So, when you (re)move generated files, please move the cleaning rules from

the Makefile to this script. This is run before Kbuild starts building

anything, so people will not be annoyed by such garbage files.

This script is not intended to grow endlessly. Rather, it is a temporary scrap

yard. Stale files stay in this file for a while (for some release cycles?),

then will be really dead and removed from the code base entirely.

These were previously generated source files. When you are building the kernel

with O=, make sure to remove the stale files in the output tree. Otherwise,

the build system wrongly compiles the stale ones.
