I'm announcing the release of the 5.0.7 kernel.
(sorry I forgot to send these out last week, my fault, the kernels were
released, but the email did not get sent...)
All users of the 5.0 kernel series must upgrade.
The updated 5.0.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.0.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

Therefore, the recommended and only supported way of using NEON/VFP in the

* isolate the NEON code in a separate compilation unit and compile it with
- '-mfpu=neon -mfloat-abi=softfp';
