Subject: [PATCH 0/2] s390x: uncouple physical and virtual memory spaces
Date: Wed, 29 Nov 2023 13:50:10 +0100	[thread overview]
Message-ID: <cover.1701261329.git.agordeev@linux.ibm.com> (raw)

Hi all,

Currently physical and virtual addresses are the same on S390X,
but in the future it is going to be uncoupled just like on any
other architecture. This series supports that feature, but it
does not impact the current and older kernel versions.

Patch 1 is basically NOP and only fix semantics.
Patch 2 uses the feature if it is available in kernel.

Thanks!
