Since the section retrieval code is implemented inside the awk script
now, the next step is to eliminate external iteration over the section
list and just retrieve the required sections inside awk on demand. This
allows calling (and processing the output of) objdump -t just once,
which saves around 8-12% of time on kernels that store modversions
as non-absolute symbols:

Instead of running the nm output through grep and then running it
through awk again, run it directly through awk, and bail of immediately
if a non-absolute symbol is found.
Also, while we're here, avoid executing the indirect parsing code

Linux commit v5.19-rc1~139^2~2 ("kbuild: link symbol CRCs at final link,
removing CONFIG_MODULE_REL_CRCS") has broken the assumption aobut
the placement of non-absolute CRC symbols in .rodata (and also affects
the architectures that used to have these symbols as absolute); rewrite
the parsing by utilising "objdump -t" output to figure out
the section(s) where the __crc_* symbols are stored and process
it instead of the hard-coded ".rodata" section. The change also speeds
up the processing a bit, around 33% on synthetic tests:

generated for latest_kernel macro, which would lead to an error (since
an RPM macro can't have an empty definition). Append %nil to the input
of the "head" command to avoid this situation.
* macros.kmp (kernel_module_package): Feed additional line with %nil
to the input of head command in the latest_kernel macro definition.

Providing "kernel-modules" with "${verrel}${dotvariant}" looks strange,
as it differs from the package and version that are actualy used for
flavored kernels.
* kmodtool (get_rpmtemplate): Add "kernel${dashvariant}-modules >= ${verrel}"
Provides to the generated spec.

A patch[1] to the kernel spec file changed the separator that is used
for kernel flavor designation from "." to "+", which broke kmodtool and
%kernel_module_package in multiple places. Try to accomodate it by
accepting both "+" and "." during parsing, and guessing which one should
be used for kernel osurce path generation.
PS. It looks like the analogous breakage was before, when it was changed
from "-" to ".". May be we should start support it back again as well.

* kmodtool (get_verrel, get_variant): Accept both "." and "+" as separators.
(get_variant_char, print_variant_char, print_kernel_source): New functions.
(get_filelist): Convert "+%1" in file list to $dotvariant, in addition
to ".%1" and "-%1".
(get_rpmtemplate): Determine a char that is used as a variant separator.
Use it in $dotvariant.
(usage): Mention "veriant_char" and "kernel_source" commands.
* macros.kmp (%kernel_module_package): Use "kernel_source" command in
"%kernel_source" definition when non-default variant is used; fall back
to ls-based heuristics when it is not available (for example, when a
version of kmodtool that doesn't support this command is used).

The following packages are added:
- kernel-abi-stablelists is used by find-requires.ksym in order to
provide information regarding kABI symbol usage. It's purely
informational and optional, however.
- redhat-rpm-config and kernel-rpm-macros are added since the generted
spec files use macros from these packages.
- elfutils-libelf-devel is used during kmod build for ORC metadata
generation (used by kernel for stack unwinding).
- kmod programs are used by find-requires.ksyms and find-proivides.ksyms
for parsing *.ko files during dependency generation.
* kmodtool (get_rpm_template): Update the list of generated
BuildRequires.
* macros.kmp (%kernel_module_package_buildreqs): Update the list of
default BuildRequires.

In RHEL 9, there's a s390x-specific "zfcpdump" kernel variant (which
replaces previous "kdump¨ variant). Add it to the list of the known
kernel variants.
* kmodtool (knownvariants): Add "zfcpdump".

we have to follow it.

Apply redhat-rpm-config-9.1.0-kmod-kabi.patch from RHEL 7 branch.
Applied only changes to kmodtool and macros (now macros.kmp), as all
others are applied already. macros.kmp also had a merge conflict due to
commits f41a8a73aa6f ("Fix kernel_source macro to match the directory
that kernel sources are installed in") and d95e9bc7b618 ("Fix directory
name mismatch in kernel_source macro (#648996)") being applied already.

- Add support for compressed kernel modules to find-provides.ksyms,
find-requires.ksyms, firmware.prov (#1622019)
* find-provides.ksyms: Try to process files whose names end with
something else than "*.ko" by guessing a decompressor and uncompressing
it in a temporary file and parsing it instead.
* find-requires.ksyms (all_provides): Likewise.
Add "(\.gz|\.bz2|\.xz)?" to the end of the module path matching regular
expression.
* firmware.prov: Add "(\.gz|\.bz2|\.xz)?" to the end of the module path
matching regular expression.
