This kernel release incorporates the following fix from Megi:
- fixed regression in Pinephone power consumption during sleep (touchscreen
was not disabled properly, consuming a lot of power)

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.

Kernel source updated to 6.1-rc7
Ext2 and Ext3 modules in aarch64 config disabled because Ext4 is backwards compatible.
2 fixes for PinePhone included in this source:
pinephone: fix power key behavior during suspend (avoid stuck key during resume)
pinephone keyboard: wait for 100ms after enabling power supply and before probing.

Replace usages of pmb:kconfigcheck-* options with
pmb:kconfigcheck-community which will be required for all devices in
community/main category. This ensures more consistent features &
behavior across devices.
Disable options
-CONFIG_NET_VENDOR_ENGLEDER
-CONFIG_NET_VENDOR_VERTEXCOM
-CONFIG_SURFACE_PLATFORM
Enable options
+CONFIG_KEYBOARD_PINEPHONE
Note by ollieparanoid: this fixes the suspend to ram issue, pma 1478
