In https://salsa.debian.org/kernel-team/linux/-/merge_requests/651 I had
initially removed the 2 Android related patches for the following
reason:

    Drop patches:
    - debian/android-enable-building-ashmem-and-binder-as-modules.patch
    - debian/export-symbols-needed-by-android-drivers.patch
    After https://bugs.debian.org/901492 the preceding 2 patches were
    created for anbox support. However in kernel 5.18 `ashmem` was removed
    from the upstream kernel and since then, anbox has not been working as
    reported in https://bugs.debian.org/1014329.
    Then in https://bugs.debian.org/1032304, titled "RM: anbox -- ROM;
    Upstream discontinued", the anbox package has been removed from the
    Debian archive. And on Anbox's GH page one can see the following:
    "It's development has however stalled in the past years and it's only
    fair to say that now in 2023 it's no longer actively developed."
    So it's of no use to continue carrying these patches.

Even though anbox is removed from the Debian archive and upstream more
or less 'dead', it turns out that Waydroid (= ~ anbox's successor) could
probably benefit from support in the Debian kernel too.

So I undid/reverted the dropping of those patches.
Removal of Android support should be done separately and ideally based on
a bug report in the BTS, hence this bug report.

In https://github.com/waydroid/waydroid/issues/811 I asked 'upstream'
for recommendations on which/how/what kernel modules to enable.

In https://git.kernel.org/linus/9e18d0c82f0c07f2a41898d4adbb698a953403ee the 
default value of BINDER_DEVICES was changed to "binder,hwbinder,vndbinder" 
whereas the Debian kernel only has "binder". Also in other places they use the 
3 values, but I haven't been able to find out *why*.
As I wouldn't be able to make the argument to change it to something else and 
the most important thing is to enable ANDROID_BINDER_IPC, which is already the 
case, there's no need to keep this bug open.

If someone *can* substantiate why and how things should be changed, they 
should file a bug report (themselves) making the case.
