2016-03-16target-ppc: Add helpers for updating a CPU's SDR1 and external HPTDavid Gibson
When a Power cpu with 64-bit hash MMU has it's hash page table (HPT) pointer updated by a write to the SDR1 register we need to update some derived variables. Likewise, when the cpu is configured for an external HPT (one not in the guest memory space) some derived variables need to be updated. Currently the logic for this is (partially) duplicated in ppc_store_sdr1() and in spapr_cpu_reset(). In future we're going to need it in some other places, so make some common helpers for this update. In addition the new ppc_hash64_set_external_hpt() helper also updates SDR1 in KVM - it's not updated by the normal runtime KVM <-> qemu CPU synchronization. In a sense this belongs logically in the ppc_hash64_set_sdr1() helper, but that is called from kvm_arch_get_registers() so can't itself call cpu_synchronize_state() without infinite recursion. In practice this doesn't matter because the only other caller is TCG specific. Currently there aren't situations where updating SDR1 at runtime in KVM matters, but there are going to be in future.

2016-03-16target-ppc: Split out SREGS get/put functionsDavid Gibson
Currently the getting and setting of Power MMU registers (sregs) take up large inline chunks of the kvm_arch_get_registers() and kvm_arch_put_registers() functions. Especially since there are two variants (for Book-E and Book-S CPUs), only one of which will be used in practice, this is pretty hard to read. This patch splits these out into helper functions for clarity. No functional change is expected.

2016-03-16spapr_pci: fix multifunction hotplugMichael Roth
Since 3f1e147, QEMU has adopted a convention of supporting function hotplug by deferring hotplug events until func 0 is hotplugged. This is likely how management tools like libvirt would expose such support going forward. Since sPAPR guests rely on per-func events rather than slot-based, our protocol has been to hotplug func 0 *first* to avoid cases where devices appear within guests without func 0 present to avoid undefined behavior. To remain compatible with new convention, defer hotplug in a similar manner, but then generate events in 0-first order as we did in the past. Once func 0 present, fail any attempts to plug additional functions (as we do with PCIe). For unplug, defer unplug operations in a similar manner, but generate unplug events such that function 0 is removed last in guest.

Using a 64bit-sized IPv6 prefix, the guest is now able to perform stateless autoconfiguration (SLAAC) and to compute its IPv6 address. This patch adds an ndp_table, mainly inspired by arp_table, to keep an NDP cache and manage network address resolution. Slirp regularly sends NDP Neighbor Advertisement, as recommended by the RFC, to make the guest refresh its route. This also adds ip6_cksum() to compute ICMPv6 checksums using IPv6 pseudo-header.

With Hyper-V enabled CPU hotplug stops working. The CPU appears in device manager on Windows but does not appear in peformance monitor and control panel. The root of the problem is the following. Windows checks HV_X64_CPU_DYNAMIC_PARTITIONING_AVAILABLE bit in CPUID. The presence of this bit is enough to cure the situation. The bit should be set when CPU hotplug is allowed for HyperV VM. The check that hot_add_cpu callback is defined is enough from the protocol point of view.

2016-03-14backup: Use Bitmap to replace "s->bitmap"Fam Zheng
"s->bitmap" tracks done sectors, we only check bit states without using any iterator which HBitmap is good for. Switch to "Bitmap" which is simpler and more memory efficient. Meanwhile, rename it to done_bitmap, to reflect the intention.
