ec0503b4f0 firmware_abi: move to include/hw/nvram/
firmware_abi.h with structs for OpenBIOS landed in hw/sparc/ by mistake
- move it to hw/nvram/ alongside fw_cfg.h.  In addition to sparc it's
included from ppc mac_nvram.c and will need to include it from prep.c in
the future.

86a8623692 memory: limit sections in the radix tree to the actual address space size
The radix tree is statically sized to fit TARGET_PHYS_ADDR_SPACE_BITS.
If a larger memory region is registered, it will overflow.

Fix by limiting any section in the radix tree to the supported size.

This problem was not observed earlier since artificial regions (containers
and aliases) are eliminated by the memory core, leaving only device regions
which have reasonable sizes.  An IOMMU however cannot be eliminated by the
memory core, and may have an artificial size.

5f9a5ea1c0 memory: Rename readable flag to romd_mode
"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region
flag, but it only applies to rom_device regions.

So rename the flag and the function to modify it after the original term
"ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode
with direct access. In any case, the scope of the flag is clearer now.

memory_region_find() is similar to registering a MemoryListener and

02ffb50448 coroutine: stop using AioContext in CoQueue
qemu_co_queue_next(&queue) arranges that the next queued coroutine is
run at a later point in time.  This deferred restart is useful because
the caller may not want to transfer control yet.

This behavior was implemented using QEMUBH in the past, which meant that
CoQueue (and hence CoMutex and CoRwlock) had a dependency on the
AioContext event loop.  This hidden dependency causes trouble when we
move to a world with multiple event loops - now qemu_co_queue_next()
needs to know which event loop to schedule the QEMUBH in.

After pondering how to stash AioContext I realized the best solution is
to not use AioContext at all.  This patch implements the deferred
restart behavior purely in terms of coroutines and no longer uses
QEMUBH.

Here is how it works:

Each Coroutine has a wakeup queue that starts out empty.  When
qemu_co_queue_next() is called, the next coroutine is added to our
wakeup queue.  The wakeup queue is processed when we yield or terminate.

035873283b qom: aggressively optimize qom casting
This patch adds a small typename cache to ObjectClass.  This allows
caching positive casts within each ObjectClass.  Benchmarking a
PPC workload provided by Aurelien, this patch eliminates every
single g_hash_table_lookup() happening during the benchmark (which
was about 2 million per-second).

With this patch applied, I get exactly the same performance (within
the margin of error) as with --disable-qom-cast-debug.

N.B. it's safe to cache typenames only from the _assert() macros
because they are always called with string literals.

f0513d2c01 target-i386: Introduce ICC bus/device/bridge
Provides a hotpluggable bus for APIC and CPU.

* icc-bridge will serve as a parent for icc-bus and provide
  mmio mapping services to child icc-devices.
* icc-device will replace SysBusDevice as a parent of APIC
  and IOAPIC devices.

997395d388 cpu: Introduce get_arch_id() method and override it for X86CPU
get_arch_id() adds possibility for generic code to get a guest-visible
CPU ID without accessing CPUArchState.
If derived classes don't override it, it will return cpu_index.

Override it on target-i386 in X86CPU to return the APIC ID.
