To support building in (a subset of) the linux-firmware files into the
kernel using the CONFIG_EXTRA_FIRMWARE option, we need to ensure that the
firmware files are installed before the Linux kernel is built, similar to
how it is done for intel-microcode.

arm64 / riscv supports building a gzip compressed 'Image' format kernel,
which is sometimes useful. From arch/arm64/Makefile:
all: Image.gz
Image: vmlinux
$(Q)$(MAKE) $(build)=$(boot) $(boot)/$@
Image.%: Image
$(Q)$(MAKE) $(build)=$(boot) $(boot)/$@
(and similar logic for riscv)
Future architectures may or may not copy this logic, so for robustness add
an explicit Image.gz format rather than copying both Image and Image.gz when
the Image format is used.

As we discussed on the mailing list, using $(<pkg>_NAME) when defining
CPE ID variables feels a bit odd and needlessly complicated. Just use
the package name directly.

The CPE type of the Linux kernel is special, it should be "o", unlike
all other packages that use "a". We therefore need to override
<pkg>_CPE_ID_PREFIX, so that the CPE ID of the linux package matches
with the CPE dictionary.

Curently, host-kmod has no option to enable it, because only
the kernel depends on it, and this is unconditional (because
we can't know if modules will be enabled in the kernel config).
But we're soon to add options to enable various features of
kmod, so we'll need a place where to show those features.

If the modules directory that corresponds to the version of the kernel
being built has been deleted, don't try to run depmod, which will
obviously fail.
This can happen for instance when the modules are stripped from the main
root filesystem, and placed into a separate filesystem image, so that
the root filesystem and the kernel can be updated separately.

On Ubuntu 18.04, make-4.1 emits spurious, incorrect "entering/leaving"
messages, which end up in the LINUX_VERSION_PROBED variable:
printf 'probed linux version: "%s"\n' "$(LINUX_VERSION_PROBED)"
probed linux version: "make[1]: Entering directory '/home/buildroot'
4.19.78-linux4sam-6.2
make[1]: Leaving directory '/home/buildroot/output/build/linux-linux4sam_6.2'"
First, the messages are displayed even though we do explicitly pass
--no-print-directory -s.
Second, the entering and leaving messages are not about the same
directory!
This *only* occurs in the following conditions:
- the user has the correct 0022 umask,
- top-level parallel is used (with or without PPD),
- initial -C is specified as well.
$ umask 0022
$ make -j16 -C $(pwd)
[...]
depmod: ERROR: Bad version passed make[1]:
[...]
(yes, 'make[1]:' is the string depmod is trying, and fails, to parse as
a version string).
If any of the three conditions above is removed, the problem no longer
occurs. Here's a table of the MAKEFLAGS:
| 0002 | 0022 |
----+-------+------------------------------------------------+--------------------------+
| no-j | --no-print-directory -- | |
noC | +------------------------------------------------+--------------------------+
| -j16 | -j --jobserver-fds=3,4 --no-print-directory -- | -j --jobserver-fds=3,4 |
----+-------+------------------------------------------------+--------------------------+
| no-j | --no-print-directory -- | w |
-C | +------------------------------------------------+--------------------------+
| -j16 | -j --jobserver-fds=3,4 --no-print-directory -- | w -j --jobserver-fds=3,4 |
----+-------+------------------------------------------------+--------------------------+
0002: umask == 0002
0022: umask == 0022
no-j: no -j flag
-j16: -j16 flag
noC: no -C flag
-C : -C /path/of/buildroot/
Only the bottom-right-most case fails...
This behaviour goes against what is documented:
https://www.gnu.org/software/make/manual/make.html#g_t_002dw-Option
5.7.4 The ‘--print-directory’ Option
[...]
you do not need to specify this option because ‘make’ does it for
you: ‘-w’ is turned on automatically when you use the ‘-C’ option,
and in sub-makes. make will not automatically turn on ‘-w’ if you
also use ‘-s’, which says to be silent, or if you use
‘--no-print-directory’ to explicitly disable it.
So this exactly describes our situation; yet 'w' is added to MAKEFLAGS.
Getting rid of the 'w' flag makes the build succeed again, so that's
what we do here (bleark, icky)...
Furthermore, the documented way to override MAKEFLAGS is to do so as a
make parameter:
https://www.gnu.org/software/make/manual/make.html#Options_002fRecursion
5.7.3 Communicating Options to a Sub-make
[...]
If you do not want to pass the other flags down, you must change the
value of MAKEFLAGS, like this:
subsystem:
cd subdir && $(MAKE) MAKEFLAGS=
However, doing so does not fix the issue. So we resort to pass the
modified MAKEFLAGS via the environment (bleark, icky)...

Commit a4eef9a395 (linux: introduce BR2_KERNEL_DTB_KEEP_DIRNAME)
introduced a new config option, but its name was not matching the
naming-scheme of the other config options.
Rename it.
We don't need legacy handling, because that config option was added very
recently and was never part of a release.

In linux, newer architectures like ARM64 and RISC-V keep their device
tree sources organized by subdirectories. When these device trees are
installed by the kernel they will keep the directory names. But
buildroot strips the prefixes when installing them into /boot or the
images directory.
Sometimes the bootloader references the device tree by name (e.g.
u-boot has the environment variable 'fdtfile') which also includes
the prefix directory.
Make it possible to keep this prefix during installation, so we can
be compatible with other distributions and make it easier for the
user, because he doesn't have to change that environment variable.

perf by itself is not a standalone package; instead, it is part of a
bigger package, linux-tools.
Even though perf is the only one to need kernel .config fixups, we still
do it in a generic way, as it blends nicely in the existing variables,
which all use a loop over all the tools.
