caif: remove CAIF NETWORK LAYER
Remove CAIF (Communication CPU to Application CPU Interface), the
ST-Ericsson modem protocol. The subsystem has been orphaned since 2013.
The last meaningful changes from the maintainers were in March 2013:
a8c7687bf216 ("caif_virtio: Check that vringh_config is not null")
b2273be8d2df ("caif_virtio: Use vringh_notify_enable correctly")
0d2e1a2926b1 ("caif_virtio: Introduce caif over virtio")
Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.
If anyone is using this code please yell!
In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a83b).
We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.
UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.
