Loading the BIOS in the mac99 machine is interesting, because there is a
PROM in the middle of the BIOS region (from 16K to 32K). Before memory
region accesses were clamped, when QEMU was asked to load a BIOS from
0xfff00000 to 0xffffffff it would put even those 16K from the BIOS file
into the region. This is weird because those 16K were not actually
visible between 0xfff04000 and 0xfff07fff. However, it worked.
After clamping was added, this also worked. In this case, the
cpu_physical_memory_write_rom_internal function split the write in
three parts: the first 16K were copied, the PROM area (second 16K) were
ignored, then the rest was copied.
Problems then started with commit 965eb2f (exec: do not clamp accesses
to MMIO regions, 2015-06-17). Clamping accesses is not done for MMIO
regions because they can overlap wildly, and MMIO registers can be
expected to perform full-width accesses based only on their address
(with no respect for adjacent registers that could decode to completely
different MemoryRegions). However, this lack of clamping also applied
to the PROM area! cpu_physical_memory_write_rom_internal thus failed
to copy the third range above, i.e. only copied the first 16K of the BIOS.
In effect, address_space_translate is expecting _something else_ to do
the clamping for MMIO regions if the incoming length is large. This
"something else" is memory_access_size in the case of address_space_rw,
so use the same logic in cpu_physical_memory_write_rom_internal.

Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

Do not take the BQL before dispatching MMIO requests of KVM VCPUs.
Instead, address_space_rw will do it if necessary. This enables completely

This opens the path to get rid of the iothread lock on vmexits in KVM
mode. On x86, the in-kernel irqchips has to be used because we otherwise
need to synchronize APIC and other per-cpu state accesses that could be
changed concurrently.
Regarding pre/post-run callbacks, s390x and ARM should be fine without
specific locking as the callbacks are empty. MIPS and POWER require
locking for the pre-run callback.
For the handle_exit callback, it is non-empty in x86, POWER and s390.
Some POWER cases could do without the locking, but it is left in
place for now.

The MMIO case is further broken up in two cases: if the caller does not
hold the BQL on invocation, the unlocked one takes or avoids BQL depending
on the locking strategy of the target memory region and its coalesced
MMIO handling. In this case, the caller should not hold _any_ lock
(a friendly suggestion which is disregarded by virtio-scsi-dataplane).

This introduces the memory region property "global_locking". It is true

This function will be used to avoid recursive locking of the iothread lock
whenever address_space_rw/ld*/st* are called with the BQL held, which is
almost always the case.
Tracking whether the iothread is owned is very cheap (just use a TLS
variable) but requires some care because now the lock must always be
taken with qemu_mutex_lock_iothread(). Previously this wasn't the case.
Outside TCG mode this is not a problem. In TCG mode, we need to be
careful and avoid the "prod out of compiled code" step if already
in a VCPU thread. This is easily done with a check on current_cpu,
i.e. qemu_in_vcpu_thread().
Hopefully, multithreaded TCG will get rid of the whole logic to kick
VCPUs whenever an I/O event occurs!

Last month, we experienced several guests crash(6cores-8cores), qemu logs
display the following messages:
qemu-system-x86_64: /build/qemu-2.1.2/kvm-all.c:976:
kvm_irqchip_commit_routes: Assertion `ret == 0' failed.
After analysis and verification, we can confirm it's irq-balance
daemon(in guest) leads to the assertion failure. Start a 8 core guest with
two disks, execute the following scripts will reproduce the BUG quickly:
irq_affinity.sh
========================================================================
vda_irq_num=25
vdb_irq_num=27
while [ 1 ]
do
for irq in {1,2,4,8,10,20,40,80}
do
echo $irq > /proc/irq/$vda_irq_num/smp_affinity
echo $irq > /proc/irq/$vdb_irq_num/smp_affinity
dd if=/dev/vda of=/dev/zero bs=4K count=100 iflag=direct
dd if=/dev/vdb of=/dev/zero bs=4K count=100 iflag=direct
done
done
========================================================================
QEMU setup static irq route entries in kvm_pc_setup_irq_routing(), PIC and
IOAPIC share the first 15 GSI numbers, take up 23 GSI numbers, but take up
38 irq route entries. When change irq smp_affinity in guest, a dynamic route
entry may be setup, the current logic is: if allocate GSI number succeeds,
a new route entry can be added. The available dynamic GSI numbers is
1021(KVM_MAX_IRQ_ROUTES-23), but available irq route entries is only
986(KVM_MAX_IRQ_ROUTES-38), GSI numbers greater than route entries.
irq-balance's behavior will eventually leads to total irq route entries
exceed KVM_MAX_IRQ_ROUTES, ioctl(KVM_SET_GSI_ROUTING) fail and
kvm_irqchip_commit_routes() trigger assertion failure.
This patch fix the BUG.

*) Do not use AI_ADDRCONFIG on listening sockets, because this flag
makes it impossible to explicitly listen on '127.0.0.1' if no global
ipv4 address is configured additionally, making this a very
uncomfortable option.
*) Add AI_V4MAPPED hint for connecting sockets.
If your system is globally only connected via ipv6 you often still want
to be able to use '127.0.0.1' and 'localhost' (even if localhost doesn't
also have an ipv6 entry).
For example, PVE - unless explicitly asking for insecure mode - uses
ipv4 loopback addresses with QEMU for live migrations tunneled over SSH.
These fail to start because AI_ADDRCONFIG makes getaddrinfo refuse to
work with '127.0.0.1'.
As for the AI_V4MAPPED flag: glibc uses it by default, and providing
non-0 flags removes it. I think it makes sense to use it.
I also want to point out that glibc explicitly sidesteps POSIX standards
when passing 0 as hints by then assuming both AI_V4MAPPED and
AI_ADDRCONFIG (the latter being a rather weird choice IMO), while
according to POSIX.1-2001 it should be assumed 0. (glibc considers its
choice an improvement.)
Since either AI_CANONNAME or AI_PASSIVE are passed in our cases, glibc's
default flags in turn are disabled again unless explicitly added, which
I do with this patch.

Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms. The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).
More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.
What a mess...

The help text says --extra-ldflags is appended to LDFLAGS so make it so.
