Upstream commit 7ecec8503af37de6be4f96b53828d640a968705f
("xen/setup: Don't relocate p2m over existing one") should be
considered for stable kernels from 4.3 up.
Machines showing the critical memory configuration seem to be
more common these days making it impossible to boot Xen with
a kernel 4.3-4.9 as dom0 without taking special measures.

Thanks for letting us know, now applied to 4.4 and 4.9-stable trees.

Upstream commit b2d7a075a1ccef2fb321d595802190c8e9b39004
("x86/pae: use 64 bit atomic xchg function in
native_ptep_get_and_clear") should be considered for stable kernels from
4.17 up (I'll send backports for older kernels when I know you are
taking the patch).
The patch seems not only to avoid intermediate L1TF vulnerable PTEs,
but there are reports of it fixing the issue mentioned in
https://bugzilla.kernel.org/show_bug.cgi?id=198497

Upstream commit f7c90c2aa4004808dff777ba6ae2c7294dd06851
("x86/xen: don't write ptes directly in 32-bit PV guests") should be
considered for stable kernels from 4.14 up (I'll send backports for
older kernels when I know you are taking the patch).
The patch avoids 32-bit Xen PV guests creating intermediate L1TF
vulnerable PTEs.
