Hello Greg,
Can you please consider including the following two patches in the stable linux-4.14.y branch? This is to avoid page faults in do_swap_page() on PV guests, usually seen on __radix_tree_lookup() [1].
f7c90c2aa400 ("x86/xen: don't write ptes directly in 32-bit PV guests") b2d7a075a1cc ("x86/pae: use 64 bit atomic xchg function in native_ptep_get_and_clear")
Thanks,
[1] - more details on https://bugzilla.kernel.org/show_bug.cgi?id=198497
