This Linux patch fixes that.

[XEN][POWERPC] HYPERVISOR_memory_op() return value now has meaning
This patch fixes a "false" failure when calling HYPERVISOR_memory_op()
from user space, where the return value fromt he hcall is expected.
With this fix, the recent bits can can create domains beyond their
RMA.
