Subject: [PATCH 0/4] s390: add kfence support
Date: Wed, 28 Jul 2021 21:02:50 +0200	[thread overview]
Message-ID: <20210728190254.3921642-1-hca@linux.ibm.com> (raw)

Hello,

this patch series adds kfence support for s390, and was mainly
developed by Sven Schnelle. Given that he is currently busy I send
this out for him, since I'd like to get an ACK for the second patch,
which touches kfence common code.

This was already discussed here:
https://lore.kernel.org/lkml/CANpmjNPAS5kDsADb-DwvdFR9nRnX47-mFuEG2vmMPn5U3i3sGQ@mail.gmail.com/

With that ACK I'd like to carry the series via the s390 tree, so it
gets upstream during the next merge window. Hopefully that's ok.

Thanks,
Heiko
