There are strange build problems with current config, I don't see sense in spending time on solving them because nobody has actually ever used this UML
vde-devel BR is probably not needed any more, but let's keep it for future...
Previous commit removed removing CONFIG_64BIT=y, but actually the config for i586 was incorrect because of that config value being set. Regenerated it with `setarch i386 make oldconfig`.
* the kernel may work OK without WiFi and firmware stuff, make it easy to uninstall it (e.g. when trying to save disk space in a VM)
* sysfsutils is not used in scriptlets, remove it
* symlinks vmlinuz-%{flavour} and initrd-%{flavour}.img have not existed for ages, they were removed lots of time ago in ROSA, there is no sense in trying to delete what does not exist and is never created
* disable Atom ISP as recommended by RussianNeuroMancer because it does not make cameras work on x86 Intel-based tablets where cameras are connected on i2c bus, but makes the camera consome power without working
* enable zswap by default and use the default allocator as in Arch Linux where zswap is enabled by default
https://wiki.archlinux.org/index.php/Zswap
* tune values of sysctls from le9 patch to make it have at least some effect on typical desktop and server systems but avoid too agressive OOM killer on systems with 2 GB RAM and less where OOM killer kills too many process
See discussion and my comments in the thread https://www.linux.org.ru/news/kernel/16052362
* remove not used variant of the patch which did not have any effect
Update existing x86 configs manually
Make an arm64 config based on them instead on the old one which was temporary copypasted from ALT Linux
In most cases I answered to `make ARCH=xxx defconfig` like this:
N/y -> Y
N/m(/y) -> M
Y/n(/m) -> Y
M/n(/y) -> M
But did not enable odd debug.
Probably too much hardware is enabled on arm64.
- rediffed most of patches, renamed files to easify further rediffs by git format-patch
- thanks to abf.io/kernels_stable for some patches for kernel 5.9
- using unofficial patch for AUFS for kernel 5.10, there may be issues with stability, try to avoid using AUFS (I would have dropped it, but MagOS wants it very much)
- pulled updates of AltHa from http://git.altlinux.org/gears/k/kernel-image-un-def.git?p=kernel-image-un-def.git;a=history;f=security/altha;hb=HEAD
- dropped patch adding sysctl to disable disk-based swap because it has not found any usage
- bpf is now in the list of LSM modules (ability to write LSM modules as BPF programs), enable it, it is potentially useful and does not seem to be harmful
- keeping kernel libc headers in older kernels for now
- dropped building external virtualbox guest modules because they are now included into the mainline kernel
- offed building VirtualBox host modules, I do not know how to keep these binary modules in sync with userspace part of VirtualBox, users can continue using dkms
- offed building kernel-shredder because it is not buildable on kernel 5.10
- updated rtl8821ce and added a dependency from its "blacklist" subpackage here (see https://github.com/tomaspinho/rtl8821ce/commit/14b536f0)
It is not clear if kernel 5.10 will receive an LTS support longer than 5.4 or not. Support until Dec, 2022 is declared right now at https://www.kernel.org/category/releases.html for 5.10 and until Dec, 2025 - for 5.4.
TODO: update kernel configs
TODO: solve problems with version of virtualbox host modules not matching version of the virtualbox package after virtualbox is updated but kernel is not rebuilt
