I had to apply a simple fixlet to the second patch: diff --git a/xen/arch/arm/platforms/xgene-storm.c b/xen/arch/arm/platforms/xgene-storm.c index 2980c0d..29c4752 100644 --- a/xen/arch/arm/platforms/xgene-storm.c +++ b/xen/arch/arm/platforms/xgene-storm.c @@ -47,7 +47,7 @@ static int map_one_mmio(struct domain *d, const char *what, printk("Additional MMIO %"PRIpaddr"-%"PRIpaddr" (%s)\n", start, end, what); - ret = map_mmio_regions(d, start, end, end - start + 1, start); + ret = map_mmio_regions(d, start, end - start + 1, start); if ( ret ) printk("Failed to map %s @ %"PRIpaddr" to dom%d\n", what, start, d->domain_id); Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
