Fix handling of escape characters in regexs and hence fix python
Deprecation warnings which will be problematic in python 3.8.
Note that some show up as:
"""
meta/classes/package.bbclass:1293: DeprecationWarning: invalid escape sequence \.
"""
where the problem isn't on 1293 in package.bbclass but in some _prepend to a
package.bbclass function in a different file like mesa.inc, often from
do_package_split() calls.

The KBUILD_BUILD_USER and KBUILD_BUILD_HOST variables were
assigned at the kernel class level, which made it impossible
to override them in the local configuration.
By setting only the default values of those variables in the
kernel class, it is now possible to override them as expected.

As was warned by commit 312ee68752fa [kconfig: announce removal of
oldnoconfig if used], oldnoconfig has been removed from the 4.20 kernel.
So we switch our default mode to olddefconfig.
commit fb16d8912 [kconfig: replace 'oldnoconfig' with 'olddefconfig',
and keep the old name as an alias] introduced olddefconfig in the 3.10
kernel, we shuffle oldnoconfig to the fallback target.
The fallback mode allows kernels between 3.10 and the currently listed
oldest kernel of 3.2 to continue to configure.

kernel-fitimage.bbclass replaces an occurance of "fitImage" in
KERNEL_IMAGETYPE_FOR_MAKE by an image type that is buildable for the
architecture (such as zImage). The kernel-fitimage.bbclass packs that
image as sub-image in a flattened image tree image (fitImage) and
deploys this fitImage along with the image tree source file (.its).
kernel-fitimage.bbclass does not alter KERNEL_IMAGETYPES, which thus
also contains "fitImage", which kernel.bbclass will also deploy
redundantly with different naming.
The result is a dual deployment with slightly different naming,
each with a set of symlinks.
The solution chosen is to have fitImage deployment be handled by
kernel-fitimage.bbclass, and have kernel.bbclass ignore fitImage
types during deployment.

With recent kernels (i.e. 4.17+) the configuration phase of the kernel
will check for capabilities/options of the compiler for CVE and other
mitigation support.
For a general kernel, we want to ensure that CC is fully defined when
the config targets are invoked (so the proper compiler will be checked).
For linux-yocto, we also need to specify the compiler/tools dependencies
for the configme task since it executes before configure and hence the
main kernel build DEPENDS will not always be in the sysroot before it
executes. Without those dependencies the kernel will be incorrectly
configured (i.e. bison is missing) or the configuration will fail the
mitigation tests.

KERNEL_IMAGETYPE_FOR_MAKE will end up containing two copies of

Commit a1690131691507bbf5853540229b3ad775b836bf removed the ability of
recipes to set KERNEL_IMAGETYPE_FOR_MAKE. Fix that by letting recipes
continue to set their own KERNEL_IMAGETYPE_FOR_MAKE if they so wish.
They may have been doing so for a while, and don't want to have their
carefully-selected value trampled on by kernel.bbclass.
This may be required if the recipe itself wants to build one type of
kernel, but post-process it into a different type, rather like the
vmlinux->vmlinux.gz support provided by kernel.bbclass.

Kernel v4.14 and newer contain the following in their Makefile:

HOSTLDFLAGS := $(HOST_LFS_LDFLAGS)

example:

GEN ./Makefile

powerpc/64: Linker on-demand sfpr functions for modules
For final link, the powerpc64 linker generates fpr save/restore
functions on-demand, placing them in the .sfpr section. Starting with
binutils 2.25, these can be provided for non-final links with
--save-restore-funcs. Use that where possible for module links.
This saves about 200 bytes per module (~60kB) on powernv defconfig

Explicitly depend on bison-native for deterministic builds, as it is required
for the build:
| HOSTCC scripts/basic/fixdep

| YACC scripts/kconfig/zconf.tab.c
| /bin/sh: bison: command not found
| scripts/Makefile.lib:217: recipe for target 'scripts/kconfig/zconf.tab.c' failed
In most cases, this dependency comes indirectly via toolchain dependencies,
specifically binutils-cross, which pulls bison-native. Different setups,
such as with external toolchain, would expose this problem, since correct
dependency is not marked explicitly.

Some distros may want to provide alternate kernel "flavors" via feeds or
within bootable images. For example, readily available builds which
provide certain diagnostic features can enable developers and testers to
more quickly resolve issues by avoiding lengthy kernel builds.
This change allows for building multiple flavors of the kernel and
module packages by templatizing kernel package names via a new
KERNEL_PACKAGE_NAME variable in kernel.bbclass. It defaults to the old
name of "kernel", but can be overridden by certain recipes providing
alternate kernel flavors.
To maintain compatibility, recipes providing alternate kernel flavors
cannot be the "preferred provider" for virtual/kernel. This is because
OE puts the preferred provider's build and source at
"tmp-glibc/work-shared/$MACHINE/kernel-build-artifacts/" and
"tmp-glibc/work-shared/$MACHINE/kernel-source/" instead of
"tmp-glibc/work/*/$PN/" like other recipes. Therefore, recipes using the
default KERNEL_PACKAGE_NAME="kernel" follows the old semantics -- build
in the old location and may be preferred provider -- while recipes using
all other KERNEL_PACKAGE_NAME's build from the normal WORKDIR and don't
provide "virtual/kernel".
Testing:
1. Add `KERNEL_PACKAGE_NAME_pn-linux-yocto-tiny = "tiny-linux"`
to local.conf so that linux-yocto-tiny may build alongside
the main kernel (linux-yocto).
2. `bitbake linux-yocto linux-yocto-tiny` to build both kernel flavors.
3. Verified image and modules IPKs exist for both:
tmp-glibc/deploy/ipk/qemux86/kernel-* for linux-yocto
tmp-glibc/deploy/ipk/qemux86/tiny-linux* for linux-yocto-tiny
4. Verified linux-yocto is the "preferred provider", and was built in
shared directory: tmp-glibc/work-shared/qemux86/kernel-*
5. Add `CORE_IMAGE_BASE_INSTALL_append_pn-core-image-base = "tiny-linux"`
to local.conf to install both kernel flavors in core-image-base.
6. `bitbake core-image-base` to build an image.
7. Verified image contains two bzImage's under /boot/, with
"yocto-standard" (linux-yocto recipe) selected to boot via symlink.

During the introduction of support for multiple kernel image types in
849b67b2e4820564b5e5c9bd4bb293c44351c5f3, do_sizecheck was changed to only
warn if any kernel was bigger than ${KERNEL_IMAGE_MAXSIZE}. (Well, it tried
to warn - it turns out that there's no function called "warn", it should be
"bbwarn".) The previous behaviour had been to fail the build if the single
kernel image did not fit.
It seems possible that people might be generating both compressed and
uncompressed kernels and only really care whether the compressed one fits.
This means that we shouldn't just always fail if any of the images are too
large. So, let's warn (correctly this time) on every image that is too
large, but only ultimately fail if no image will fit. The build will also
fail if ${KERNEL_IMAGETYPES} is empty, but I hope that no-one needs to do
that.
While we're here correct a typo in the KERNEL_IMAGE_MAXSIZE validity check.

fallback to REPRODUCIBLE_TIMESTAMP_ROOTFS as the last resort.
Also export KCONFIG_NOTIMESTAMP=1.
2. When compressing vmlinux.gz, use gzip "-n" option
3. Kernel and kernel modules contain hard coded paths referencing the host
build system. This is usually because the source code contains __FILE__
at some place. This prevents binary reproducibility. However, some compilers
allow remapping of the __FILE__ value. If we detect the compiler is capable
of doing this, we replace the source path $(S) part of __FILE__ by a string "/kernel-source".
For example:
/data/master/build/tmp/work-shared/qemux86/kernel-source/drivers/media/v4l2-core/videobuf2-core.c
will be replaced by a reproducible value:
/kernel-source/drivers/media/v4l2-core/videobuf2-core.c.

KERNEL_IMAGETYPES lists all the kernel images that we want to build. in
cb17b6c2a7 (kernel.bbclass: support kernel image type of vmlinux.gz), some logic
was added to support vmlinux.gz which is not a target built by kernel
makefiles (only vmlinux). It is clear that the goal of this logic is only to
support vmlinux.gz and not others compressed format (such as Image.gz) which are
valid target for kernel makefiles.
For Image.gz we should rely on the kernel makefiles and not do the compression
in kernel class.
This patch updates the logic used to filter out non supported kernel target from
KERNEL_IMAGETYPES, and make vmlinux.gz a 'special case', instead of *.gz. If
more special cases are needed in the future, we could add them in a similar way.
This patch should be a no-op for anyone using vmlinux or vmlinux.gz, and on top
of that it is fixing the build for Image.gz which was not working until now.

By exporting KBUILD_BUILD_USER with a pre-defined value we improve the
reproducibility of the kernel and remove the requirement for whoami in the
HOSTTOOLS.
KBUILD_BUILD_HOST also helps improve the reproducibility of the kernel.

Having no opt-out method and adding the task to linux-yocto.inc was
causing issues. For example, linux-yocto-dev would often fail because
it uses AUTOREV with no way to dynamically change the PV.
Add a variable to turn off the sanity check, allowing an easy opt out,
and set the opt-out variable in linux-yocto-dev, fixing the issue with
AUTOREV.

It isn't clear that the README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt
file in the deploy directory warrants the complexity it brings elsewhere.
Let's just remove it entirely.
In particular, if two do_image_complete tasks run in parallel they risk
both trying to put their image into ${DEPLOY_DIR_IMAGE} at the same time.
Both will contain a README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt
file. In theory this should be safe because "cp -alf" will just cause one
to overwrite the other. Unfortunately, coreutils cp also has a race[1]
which means that if one copy creates the file at just the wrong point the
other will fail with:
cp: cannot create hard link ‘..../tmp-glibc/deploy/images/pantera/README_-_DO_NOT_DELETE_FILES_IN_THIS_D.txt’ to
+‘..../tmp-glibc/work/rage_against-oe-linux-gnueabi/my-own-image/1.0-r0/deploy-my-own-image-complete/README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt’: File exists

consider the vmlinuz ELF kernel but some devices do reqire a raw vmlinuz.bin
(as for example gcw0 in meta-handheld booted by ubiboot).
Expand the above mentioned patch to consider this case.

The OVS fails to function and the kernel modules cannot be found by
any of the kernel tools such as depmod because they are installed
into the wrong directory in multilib 64bit/32bit bulids.
