Modified Files: src/sys/arch/xen/x86 [netbsd-5]: xen_bus_dma.c Log Message: Pull up following revision(s) (requested by jym in ticket #1334): sys/arch/xen/x86/xen_bus_dma.c: revision 1.20 Although Xen's documentation states that the address_bits field is not used by XENMEM_decrease_reservation, it is checked by the hypervisor. In certain circumstances (stack leak), the field could have an improper value, leading to a fail of the hypercall. Set it to 0 ("no addressing restriction") to avoid that. Patch tested by Sam Fourman and h...@. This should fix the rare "failed allocating DMA memory" encountered under NetBSD dom0.
