182735efaf cpu: Make first_cpu and next_cpu CPUState
Move next_cpu from CPU_COMMON to CPUState.
Move first_cpu variable to qom/cpu.h.

gdbstub needs to use CPUState::env_ptr for now.
cpu_copy() no longer needs to save and restore cpu_next.

2ff3de685a Simplify -machine option queries with qemu_get_machine_opts()
The previous two commits fixed bugs in -machine option queries.  I
can't find fault with the remaining queries, but let's use
qemu_get_machine_opts() everywhere, for consistency, simplicity and
robustness.

29b358f93a pci: Add root bus parameter to pci_nic_init()
At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root.  As we add support for
multiple PCI roots, that may no longer be the case.  This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters.  NICs created new-style, with
-device can of course be put anywhere.

ec4936e1a4 pseries: Fix compiler warning (conversion of pointer to integral value)
This kind of type cast must use uintptr_t or target_ulong to be portable

159f8286b7 target-ppc: Change default machine for 64-bit
Currently, for qemu-system-ppc64, the default machine type is 'mac99'.
The mac99 machine is not being actively maintained, and represents a
bizarre hybrid of components that never actually existed as a real system.
This patch changes the default machine to 'pseries', which is actively
maintained and works well with most modern ppc64 Linux distributions as a
guest.

0cbad81f70 pseries: Fixes and enhancements to L1 cache properties
PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache.  We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).

We were also missing some of the required cache properties.  This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases).  We also
add the [id]-cache-size properties.

Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs.  The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against.  In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.

2cf3eb6df5 PPC: Remove env->hreset_excp_prefix
This value is not needed if we use correctly the MSR[IP] bit.

excp_prefix is always 0x00000000, except when the MSR[IP] bit is
implemented and set to 1, in that case excp_prefix is 0xfff00000.

The handling of MSR[IP] was already implemented but not used at reset
because the value of env->msr was changed "manually".

The patch uses the function hreg_store_msr() to set env->msr, this
ensures a good handling of MSR[IP] at reset, and therefore a good value
for excp_prefix.

0d09e41a51 hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

7b56516058 pseries: Move XICS initialization before cpu initialization
Currently, the pseries machine initializes the cpus, then the XICS
interrupt controller.  However, to support the upcoming in-kernel XICS
implementation we will need to initialize the irq controller before the
vcpus.  This patch makes the necesssary rearrangement.  This means the
xics init code can no longer auto-detect the number of cpus ("interrupt
servers" in XICS terminology) and so we must pass that in explicitly from
the platform code.

89dfd6e1b3 pseries: Remove "busname" property for PCI host bridge
Currently the "spapr-pci-host-bridge" device has a "busname" property which
can be used to override the default assignment of qbus names for the bus
subordinate to the PHB.  We use that for the default primary PCI bus, to
make libvirt happy, which expects there to be a bus named simply "pci".
The default qdev core logic would name the bus "pci.0", and the pseries
code would otherwise name it "pci@800000020000000" which is the name it
is given in the device tree based on its BUID.

The "busname" property is rather clunky though, so this patch simplifies
things by just using a special case hack for the default PHB, setting
busname to "pci" when index=0.

a4e044c30e pseries: Fix breakage in CPU QOM conversion
Commit 259186a7d2 "cpu: Move halted and
interrupt_request fields to CPUState" broke the pseries machine.  That's
because it uses CPU() instead of ENV_GET_CPU() to convert from the global
first_cpu pointer (still a CPUArchState) to a CPUState.  This patch fixes
the breakage.
