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.

riscv/purgatory: Omit use of bin2c
The .incbin assembler directive is much faster than bin2c + $(CC).

Do similar refactoring as in commit 4c0f032d49 ("s390/purgatory:
Omit use of bin2c").

Please note the .quad directive matches to size_t in C (both 8 byte)
because the purgatory is compiled only for the 64-bit kernel.
(KEXEC_FILE depends on 64BIT).

Masahiro Yamada 1476fee5c5 kbuild: add a script to remove stale generated files
We maintain .gitignore and Makefiles so build artifacts are properly
ignored by Git, and cleaned up by 'make clean'. However, the code is
always changing; generated files are often moved to another directory,
or removed when they become unnecessary. Such garbage files tend to be
left over in the source tree because people usually git-pull without
cleaning the tree.

This is not only the noise for 'git status', but also a build issue
in some cases.

One solution is to remove a stale file like commit 223c24a7db ("kbuild:
Automatically remove stale <linux/version.h> file") did. Such workaround
should be removed after a while, but we forget about that if we scatter
the workaround code in random places.

So, this commit adds a new script to collect cleanings of stale files.

As a start point, move the code in arch/arm/boot/compressed/Makefile
into this script.
