We should sync params->ram_size after we fixup memory size on
a alignment boundary. Otherwise Guest would exceed the actual

PAPR defines LIOBNs (Logical IO Bus Numbers) to be 32-bit, and we check for
values that aren't in the code for H_PUT_TCE. This patch factors the check
into spapr_tce_find_by_liobn(), which already checks if a 32-bit LIOBN
actually exists. This will become more important as future patches add
other hypercalls which need to look up a LIOBN.
At the same time we fix the typo in the message.

This patch implements a get_dev_path qdev hook for the pseries paravirtual
VIO bus. With upcoming savevm support, this will become very important for
scsi disks hanging of VIO virtual SCSI adapters. scsibus_get_dev_path
uses the get_dev_path of the parent adapter if available, but otherwise
just uses a local channel/target/lun number to identify the device. So if
two disks are present in the system having the same target and lun on
seperate VIO scsi adapters, savevm cannot distinguish them. Since the
conventional way of using VSCSI adapters is to have just one disk per
adapter, such a conflict is very likely.

Curerntly the pseries VIO device code contains quite a few explicit
uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe,
and not the conventional way of doing things in the QOM model. This
patch converts the code to use the QOM convention of per-type macros
to do verified casts with OBJECT_CHECK().

Under certain circumstances the emulation for the pseries "XICS" interrupt
controller was clearing a pending interrupt from the XISR register, without
also clearing the corresponding priority variable. This will cause
problems later when can trigger sanity checks in the under-development

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.

On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.
This went unnoticed, because they used to boot at the same location our flash
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.
Set the initial IP to something reasonable for -M mac99.

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.

Many of these should be cleaned up with proper qdev-/QOM-ification.

On real hardware the ppc hash page table is stored in memory; accordingly
our mmu emulation code can read a hash page table in guest memory. But,
when paravirtualized under PAPR, the real hash page table is in host
memory, accessible to the guest only via hypercalls. We model this by
also allowing the MMU emulation code to access a specially allocated hash
page table outside the guest's memory image. At present these two options
are implemented with some ugly conditionals at each access point in the mmu
emulation code. In the implementation of the PAPR hypercalls, we assume
the external hash table.
This patch cleans things up by adding helpers to load and store from the
hash table for both 32-bit and 64-bit hash mmus. The 64-bit versions
handle both the in-guest-memory and outside guest memory cases. The 32-bit
versions only handle the in-guest-memory case since no 32-bit systems can
have an external hash table at present.

Currently cpu.h contains a number of definitions relating to the 64-bit
hash MMU. Some are used in the MMU emulation code, but some are only used
in the spapr MMU management hcall implementations.
This patch moves these definitions (except for a few that are needed
more widely) into mmu-hash64.h header, shared between the MMU emulation
code and the spapr hcall code. The MMU emulation code is also updated to
actually use a number of those definitions in place of hard coded
constants.
Similarly, we add new analogous definitions to mmu-hash32.h and use those
in place of many hard-coded constants in mmu-hash32.c

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.

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.

Commit 259186a7d2f7184efc96ae99bc5658e6159f53ad "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.
