Subject: [PATCH stable 4.9 00/23] powerpc backports for 4.9
Date: Sat, 2 Jun 2018 21:08:45 +1000 [thread overview]
Message-ID: <20180602110908.29773-1-mpe@ellerman.id.au> (raw)
Hi Greg,
Please queue up this series of patches for 4.9 if you have no objections.
The first one is not a backport but a fix for a previous backport.
cheers
