We don't need to pass device address for pc-bios using gr7 anymore as the pcbios completely relies on diag308 now, so we can remove it from qemu. devno, ssid and cssid are migrated but the value was never reused, so we can safely ignore these fields and migrate 0.

2016-05-17pc-bios/s390-ccw: Get device address via diag 308/6Alexander Yarygin4-13/+95
To IPL from a device, pc-bios receives from qemu a device address via general register 7. The better way to do it is to use diag308/6 instruction which returns so called "IplParameterBlock". IplParameterBlock contains the device address for IPL and additional parameters that can be used by pc-bios. This patch allows pc-bios to get device address via diag308/6 and doesn't use gr7 passed boot information anymore.

The IplParameterBlock struct currently has only 200 bytes filled, but it can be up to 4K. This patch converts the struct to union with a fully populated struct inside it and second struct with old values. For compatibility reasons we disable migration of the extended iplb field for pre-2.7 machines. Also a guest still can read/write only the first 200 bytes of IPLB for now.

2016-05-16hw/intc/arm_gic: add tracepointsHollis Blanchard2-0/+20
These are obviously critical to understanding interrupt delivery: gic_enable_irq gic_disable_irq gic_set_irq (inbound irq from device models) gic_update_set_irq (outbound irq to CPU) gic_acknowledge_irq The only one that I think might raise eyebrows is gic_update_bestirq, but I've (sadly) debugged problems that ended up being caused by unexpected priorities. Knowing that the GIC has an irq ready, but doesn't deliver to the CPU due to priority, has also proven important.
