Enable options required for the Android 11 image inside waydroid:
* CONFIG_BPF_SYSCALL
* CONFIG_CGROUP_BPF
* CONFIG_PSI (already set for this kernel)
* not CONFIG_PSI_DEFAULT_DISABLED (already set for this kernel)
The same will be done for all devices in main and community in the
following patches. Also add V=1 for all kernels I'm modifying that are
below 6.2 (see issue 1990).
Kernel configuration addition:
Just like on the PinePhone Pro I enabled the newly added Lazy RCU scheduler.
RCU_LAZY can help battery-powered systems like the PinePhone Pro in a few ways:
1. Reduced CPU usage: Because RCU_LAZY allows readers to access shared data structures without acquiring locks or other synchronization primitives,
it reduces the amount of CPU time that is required to manage synchronization. This can be particularly beneficial in battery-powered systems,
where reducing CPU usage can extend battery life.
2. Reduced memory usage: RCU_LAZY delays the creation of multiple versions of the shared data structure until they are actually needed.
This reduces the amount of memory that is required to store these versions.
In battery-powered systems, where memory usage can be a critical resource, this can help to conserve power.
3. Reduced synchronization overhead: RCU_LAZY reduces the overhead of synchronization by delaying the creation of multiple versions of the shared data structure.
This can reduce the amount of time that is spent acquiring and releasing locks or other synchronization primitives,
which can help to conserve power in battery-powered systems.

linux-postmarketos-omap now supports the Nokia N900 and its OMAP3430 SoC, so
drop this device-specific fork

Switch from armhf to armv7
- Apart of the usual stuff CONFIG_CRYPTO_AES_ARM_BS must be disabled
otherwise it breakes kernel compilation with some weird assembler error
Netboot
- CONFIG_BLK_DEV_NBD=y enables /dev/nbd support
- nbd.max_part=16 kernel parameter must be added otherwise it's zero
which causes that kpartx cannot create partitions

Soon openrc-settingsd (hostnamed) will uses these properties so the
information can be exposed to apps like GNOME Settings.
Let's also move the shellcheck comment to the outer scope, otherwise
we'd need four of these comments now, and let's not use ${} but just $.
Bugfix release, nothing major though. Full changelog:
https://gitlab.com/postmarketOS/postmarketos-mkinitfs/-/tags/2.1.1
Note: git was dropped as a makedepends because it's not actually
needed... I forgot that I could just set VERSION at build time. Oops.

Remove maintainers who could not be reached to test v22.12. Add exkc as
maintainer for firmware-pine64-rockpro64 as discussed in review of this
patch.

This is a revert of the change introduced in 4eda0715 to support an
uncompressed initramfs-extra. osk-sdl support results in an initramfs-extra
that is too big for some devices with a small (traditional) /boot partition
