2127accd44 build: create $(PKG_SYMVERS_DIR) if non-existent
Commit 5d76065 moved the creation of the symvers directory to
include/kernel-build.mk. This is fine when building from scratch. But
when unpacking an SDK the directory doesn't exist and because the kernel
won't be built (again) this directory will not be created by the build
system, causing build failure if make tries to copy files into it.

This moves the creation of the symvers directory back into
include/kernel.mk so that the directory is created in any case.

4627b5df69 build: move symvers files to kernel build dir
The symvers files of older kernel versions are incompatible with the ones
from 5.4, so changing the kernel version without running make clean was
causing build failures in kernel module packages.
Fix this by moving the directory, ensuring that symvers files get thrown
away with a kernel version change

4ed356fa71 kernel.mk: add KCFLAGS to make kmods reproducible
Some kmods (gpio-hotplug, wireguard) store the build path in the
compiled files and therefore make it harder to rebuild the official
binaries. As the same "iremap" function is used as for other binaries,
the change is compatible with gcc7 and 8.

Tested with both gcc7 and gcc8 resulting in build path independent
reproducible builds.

5f8e587240 build: force disable stack validation during kernel build on non-linux systems
The check for libelf in the kernel build is not enough, because the code that
uses libelf for stack validation is completely non-portable, as it tries to
include asm/types.h and relies on kernel types in user space.

Until this is fixed properly, the only solution is to disable this on any non

c3e31b6a9b build: skip kernel stack validation when building on macOS
Since we switched to 4.19, the kernel build checks for libelf to decide if
it should build tools for stack validation.

On macOS, this check fails during target/compile, but succeeds during package
build (because of the pkg-config path picking up target libraries).

94464cfca2 build: fix external module symbol collection if build_dir is a symlink
e26ffb31df fixed only embedded modules
symbol collection. If we are building external modules, like broadcom-wl
or lantiq dsl stuff then modules which do EXPORT_SYMBOL have unresolved
paths in Module.symvers and external module which depend on other
external modules will have empty dependencies, leading to broken
module loading.
This was discussed on IRC with Jonas some time ago.
Fix this by handling both resolved and unresolved paths.

2b6facc8d4 include: kernel.mk: simplify module autoloading
Let the generic postinstall script invoke "kmodloader" when the just
installed package contains any /etc/module.d/ entries.

This allows us to skip the explicit "insert_module()" calls in the
package postinstall.

Due to the removed insert_module calls we do not need to assemble a
complete list of modules per package anymore, which allows for vast
simplification of the package generation code.

While we're at it, also support specifying default parameters for
modules using either the MODPARAM or MODPARAM.modulename variables
in KernelPackage.

8e0e0e7d8b include: Determine MODULES_DIR correctly for external/git kernels
When using external or git cloned kernels, any kind of modifications
will alter KERNELRELEASE. LEDE still tries to stage modules in
lib/modules/$(LINUX_UNAME_VERSION) and LINUX_UNAME_VERSION is based on
KERNEL_PATCHVER (indirectly) so this does not work, and we lose all
kinds of automatic modules loading.

To remedy that, just cat $(LINUX_DIR)/include/config/kernel.release
which is late enough the kernel has prepared this file, and is correctly
tracking changes done throughout the kernel.

576621f1e3 linux: add support of Synopsys ARC770-based boards
This patch introduces support of new boards with ARC cores.

 [1] Synopsys SDP board
     This is a new-generation development board from Synopsys that
     consists of base-board and CPU tile-board (which might have a real
     ASIC or FPGA with CPU image).
     It sports a lot of DesignWare peripherals like GMAC, USB, SPI, I2C
     etc and is intended to be used for early development of ARC-based
     products.

 [2] nSIM
     This is a virtual board implemented in Synopsys proprietary
     software simulator (even though available for free for open source
     community). This board has only serial port as a peripheral and so
     it is meant to be used for runtime testing which is especially
     useful during bring-up of new tools and platforms.
     What's also important ARC cores are very configurable so there're
     many variations of options like cache sizes, their line lengths,
     additional hardware blocks like multipliers, dividers etc. And this
     board could be used to make sure built software still runs on
     different HW configurations.
