Other x86 items that among the x86 maintainers we've marked 4.18 material:

- x86: reduce cache flushing overhead
(v2: https://lists.xen.org/archives/html/xen-devel/2023-05/msg00242.html)

- DOITM (Andrew meaning to post an alternative to
https://lists.xen.org/archives/html/xen-devel/2022-09/msg01132.html, which
likely would derive from
https://github.com/xenserver/xen.pg/blob/XS-8.3.x/patches/x86-Activate-Data-Operand-Invariant-Timing-Mode-by-d.patch)

Plus, affecting all architectures:

- runstate/time area registration by (guest) physical address
(v3: https://lists.xen.org/archives/html/xen-devel/2023-05/msg00304.html)

- annotate entry points with type and size
(v4: https://lists.xen.org/archives/html/xen-devel/2023-08/msg00470.html)
