Currently, the linux kernel will apply some fixups on its .config file,
based on whether some packages are enabled or not. That list of
conditional fixups is getting bigger and bigger with each new package
that needs such fixups, culminating with the pending firewalld one [0].
Furthermore, these fixups are not accessible to packages in br2-external
trees.
Add a new per-package variable, that packages may set to the commands to
run to fixup the kernel .config file, which is added at the end of the
linux' own fixups.
This opens the possibility to write things like;
define FOO_LINUX_CONFIG_FIXUPS
$(call KCONFIG_ENABLE_OPT,BLA)
endef
Of course, it also opens the way to run arbitrary commands in there, but
any alternative that would be declarative only, such as a list of
options to enable or disable (as an example):
FOO_LINUX_CONFIG_FIXUPS = +BAR -FOO +BUZ="value"
.. is not very nice either, and such lists fall flat when a value would
have a space.
For packages that we have in-tree, we can ensure they won't play foul
with their _LINUX_CONFIG_FIXUPS. For packages in br2-external trees,
there's nothing we can do; users already have the opportunity to hack
into the linux configure process by providing LINUX_PRE_CONFIGURE_HOOKS
or LINUX_POST_CONFIGURE_HOOKS anyway...
.. which brings the question of why we don't use that to implement the
per-package fixups. We don't, because _PRE or _POST_CONFIGURE_HOOKS are
run after we run 'make oldconfig' to sanitise the mangled .config.

The help text of BR2_LINUX_KERNEL_IMAGE_NAME is somewhat incomplete,
in the sense that it assumes just a filename can be passed, while it
can be a relative path, such as 'compressed/vmlinux.bin.z'. So make it
clear that such paths are relative to arch/ARCH/boot/.
Also, drop the part about this being only useful for Xtensa as this is
not true: on MIPS it might be needed as well for some specific image
types.

The Linux kernel image is typically found in arch/ARCH/boot/, which is
why LINUX_IMAGE_PATH is defined as:
LINUX_IMAGE_PATH = $(LINUX_ARCH_PATH)/boot/$(LINUX_IMAGE_NAME)
However, on MIPS, some kernel image types are available from
arch/mips/boot/compressed, or even at the top-level directory. For
such cases, LINUX_IMAGE_NAME might be set (using
BR2_LINUX_KERNEL_IMAGE_NAME) to values such as:
compressed/vmlinux.bin.z
or
../../../uzImage.bin
Except that the line:
$(INSTALL) -m 0644 -D $(LINUX_IMAGE_PATH) $(1)/$(LINUX_IMAGE_NAME)
will lead to such images be installed in:
$(TARGET_DIR)/boot/compressed/vmlinux.bin.z
$(BINARIES_DIR)/compressed/vmlinux.bin.z
and:
$(TARGET_DIR)/boot/../../../uzImage.bin
$(BINARIES_DIR)/../../../uzImage.bin
which of course is completely bogus.
So let's install them under their name, not their full relative path
to arch/ARCH/boot/.

When a package installs a kernel module, it is currently not possible to
have it loaded with modprobe or when the kernel requests an alias for
it, as the module is not listed in /lib/modules/<kernel-version>/modules.dep
and the associated files.
So, we need to run depmod after all packages are installed, to register
any such out-of-tree module.
This means we should be able to let go of calling depmod at the time the
kernel is installed, but if we pass an invalid command, the kernel
whines:
DEPMOD 5.4.27
./scripts/depmod.sh: 46: /dev/null: Permission denied
make[2]: *** [Makefile:1326: _modinst_post] Error 126
This is because the kernel does not directly call to depmod, but uses a
wrapper that is not happy if depmod is not depmod.
Since the call to depmod does not cost much, we just keep it.

Enabling SELinux support in the kernel requires several options, many
of which are in different areas. These options are as follows:
- CONFIG_AUDIT
- CONFIG_DEFAULT_SECURITY_SELINUX
- CONFIG_INET
- CONFIG_NET
- CONFIG_SECURITY
- CONFIG_SECURITY_NETWORK
- CONFIG_SECURITY_SELINUX
As such, if a user selects the libselinux package, it is much easier
to select these options for them, much like we already do with other
packages such as systemd or iptables.

The content of COPYING changed between v4.16 and v4.17. Since kernels
before and after the change are supported, storing the hash for this

While the kernel is built for the target, the build may need various host
libraries depending on config (and kernel version), so use HOST_MAKE_ENV
instead of TARGET_MAKE_ENV.
In particular, this ensures that our host-pkgconf will look for host
libraries and not target ones.
Fixes building scripts/dtc for Buildroot configurations enabling libyaml and
host-pkgconf for kernels after commit 067c650c45 (dtc: Use pkg-config to
locate libyaml).
With this enabled, we can drop the PKG_CONFIG_* variables for the
_NEEDS_HOST_LIBELF conditional, as those are included in HOST_MAKE_ENV.

When 'make' includes a new Makefile, it appends its path to the MAKEFILE_LIST
variable. From that variable, we construct a few set of derivative
variables:
pkgdir = $(dir $(lastword $(MAKEFILE_LIST)))
pkgname = $(lastword $(subst /, ,$(pkgdir)))
Essentially, pkgdir is the full directory where the package is located
(either relative to Buildroot's top directory for in-tree packages, or
absolute for packages in br2-external trees), while pkgname is the last
component of that directory.
pkgdir is in turn used to seed FOO_PKGDIR.
This all happens when we eventually call the package-generic infra,
later down in the file.
When they are parsed, the Makefiles for each linux-extensions are
appended to MAKEFILE_LIST, after the linux.mk one. But since they are
located in the same directory as the main linux.mk, the last component
of MAKEFILE_LIST, which is no longer the main linux.mk, will still yield
the correct values for the linux package.
This is a tough assumption we made there and then.
When we added the support for br2-external linux extensions, we where
very cautious to explicitly scan them from a directory named 'linux', so
that this would yield the correct package name.
And that worked well so far, until someone needed to build an older
kernel, for which our conditional patch is needed, and which just
failed:
/bin/bash: [...]/buildroot-external-linux-test/linux//0001-timeconst.pl-Eliminate-Perl-warning.patch.conditional: No such file or directory
When we scan linux extensions from a br2-external tree, the last
component of MAKEFILE_LIST is no longer in the same directory as the
main linux.mk, and thus the assumption above falls to pieces...
Again, when we added support for linux extensions from br2-external,
although we cared about the package name (pkgname), we completely missed
out on the package directory, and the LINUX_PKGDIR variable.
We do not have a very clean way out of this mess, but we have a nice
dirty trick: Scan the linux extensions from a br2-external tree before we
scan the in-tree ones. That way, the last component of MAKEFILE_LIST is
back to one that is in the same directory as the main linux.mk, and
we're back on tracks.
This is still very fragile, though, but short of a complete overhaul on
how packages are parsed and evaluated, this is the best we can come in
short order.

ARC processors have configurable size of MMU page. This configuration
happens during ASIC design and couldn't be changed in final silicone
not to mention runtime changes.
Given PAGE_SIZE macro is used a lot throughout the Linux kernel sources
we just hardcode a required value during the kernel configuration.
We used to support different MMU page sizes for ARC in Buildroot for
quite some time now but so far we only tweaked uClibc on the matter.
That left us with the kernel configured with whatever was in used defconfig.
In most of real cases that's OK because typically we're building firmware
for a particular ASIC which is supposed to have a unique kernel defconfig.
But if we're dealing with FPGA-based boards or even simlators like
Synopsys DesignWare nSIM or QEMU it's possible to have dfferent MMU page
size configured in that target mostly for the sake of testing.
And so we're trying to solve 2 problems here:
1. Make sure both user-space (via libc settings) and the Linux kernel
are "on the same page", i.e. expect to use the same MMU page size.
2. Simplify process of testing different page sizes.
As now we first need to set page size in Buildroot and then in the
kernel via "make linux-configure" or via Kconfig fragment.

Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option is only
available to be selected by another config option. This option controls
if the Linux build system should build the DTB itself, or if buildroot
explicitly calls the Linux Makefile like "make something.dtb".
My use case: I want to build an OpenRISC image with a custom device tree
file. OpenRISC does not support appended DTBs, and I'm not using a
bootloader, but link everything into a single kernel (vmlinux) image.
The kernel option CONFIG_OPENRISC_BUILTIN_DTB allows me to specify a dtb
file, which is typically located in the kernel source tree in
arch/openrisc/boot/dts/NAME.dts.
Since my dts file is not part of the upstream kernel, I have two
options: either patch the kernel to include the DTS file, and then
specify it using the CONFIG_OPENRISC_BUILTIN_DTB option.
Or use buildroot's BR2_LINUX_KERNEL_CUSTOM_DTS_PATH config option to
copy any DTS file to the kernel source tree, and then specify this file
with CONFIG_OPENRISC_BUILTIN_DTB as before.
However, the second option also requries the buildroot option
BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT to be set, otherwise I end up with a
"make -C kerneldir NAME.dts" call, which doesn't work (no such target
exists).
Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option exists, but it's
not visible/available. Simply making it available solves the problem for
me nicely.

>From patch [1] included in kernel >= 5.0:
"The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.
In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.
These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.
Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias."
Werror is set by default while building ppc kernel [2], but
some warning can be introduced while building current kernel with
newer compiler (for example building kernel 4.19 with gcc 9.1).
For the same reason why we remove Werror in packages's compiler
flags. Building with Werror is not bulletproof when we start
using a newer compiler that introduce new warnings.
This is the case here.
Also this option is a bit strange since it's specific to ppc kernels:
"The intention is to make it harder for people to inadvertantly
introduce warnings in the arch/powerpc code."
Other kernel developers on other arch may be interested by a
similar/more generic option.
So, It's clearly intended for kernel developers.
Instead of backporting this patch [1] to kernel 4.19, select
unconditionally the Kconfig option CONFIG_PPC_DISABLE_WERROR
that allow to disable Werror.
