[Xen-devel] Linux'es SLUB incompatible with Xen?



Linux-Xen maintainers,

are you aware that SLUB's use of percpu_cmpxchg16b_double() is
currently incompatible with Xen when run on old, not cmpxchg16b
capable x86-64 CPUs (the problem being this_cpu_cmpxchg16b_emu's
non-paravirtualized use of CLI)? Or is that a simple "we don't care -
don't run Xen on such old systems" (despite everything else, including
the hypervisor, working fine there)?

Jan
