Linus Torvalds 69dac8e431 RISC-V Patches for the 5.20 Merge Window, Part 2

There's still a handful of new features in here, but there are a lot of
 fixes/cleanups as well:
 
 * Support for the Zicbom for explicit cache-block management, along with
   the necessary bits to make the non-standard cache management ops on
   the Allwinner D1 function.
 * Support for the Zihintpause extension, which codifies a go-slow
   instruction used for cpu_relax().
 * Support for the Sstc extension for supervisor-mode timer/counter
   management.
 * Many device tree fixes and cleanups, including a large set for the
   Canaan device trees.
 * A handful of fixes and cleanups for the PMU driver.

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.

rm -f arch/powerpc/purgatory/kexec-purgatory.c

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.
