I'm announcing the release of the 4.3.1 kernel.
All users of the 4.3 kernel series must upgrade.
The updated 4.3.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.3.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

Trying this stable patch on an older HP Pavilion dv7 laptop fails while version
4.3.0 works.
It seems that no kernel modules get loaded, resulting in network and several
input devices missing. Only difference I see in dmesg is
Problem loading in-kernel X.509 certificate (-74)
Attaching my config which is the same as for 4.3.0.
Any idea?
Regards,
jvp.

Yes, commit cc25b994acfbc901429da682d0f73c190e960206 in Linus's tree
should fix this, but this should also be an issue for you with 4.3.0, I
don't think anything specifically broke this between .0 and .1.
I'll try to get a 4.3.2 out later today with this fix.
