  scsi-bus: fix transfer length and direction for VERIFY command

The amount of bytes to transfer depends on the BYTCHK field.
If any data is transferred, it is sent to the device.

  scsi-disk: fix VERIFY emulation

VERIFY emulation was completely botched (and remained botched through
all the refactorings).  The command must be emulated both in check-medium
mode (BYTCHK=00, which we implement by doing nothing) and in check-bytes
mode (which we do not implement yet).  Unlike WRITE AND VERIFY (which we
treat simply as WRITE with FUA bit set), VERIFY cannot be handled like
READ.  In fact the device is _receiving_ data for VERIFY, not _sending_
it like READ.

  virtio-ccw: move virtio_ccw_stop_ioeventfd to virtio_ccw_busdev_unplug

Similar to the PCI bug that prompted these patches, virtio-ccw will
segfault after the reworking of hotplug/hot-unplug.  Prepare for
this by moving virtio_ccw_stop_ioeventfd to before the freeing
of the proxy device.

A better place for this could be the device_unplugged callback
for the virtio-ccw bus.  However, we do not yet have a callback
that works: this patch avoids the problem while leaving the tree
bisectable.

  virtio-bus: cleanup plug/unplug interface

Right now we have these pairs:

- virtio_bus_plug_device/virtio_bus_destroy_device.  The first
  takes a VirtIODevice, the second takes a VirtioBusState

- device_plugged/device_unplug callbacks in the VirtioBusClass
  (here it's just the naming that is inconsistent)

- virtio_bus_destroy_device is not called by anyone (and since
  it calls qdev_free, it would be called by the proxies---but
  then the callback is useless since the proxies can do whatever
  they want before calling virtio_bus_destroy_device)

And there is a k->init but no k->exit, hence virtio_device_exit is
overwritten by subclasses (except virtio-9p).  This cleans it up by:

- renaming the device_unplug callback to device_unplugged

- renaming virtio_bus_plug_device to virtio_bus_device_plugged,
  matching the callback name

- renaming virtio_bus_destroy_device to virtio_bus_device_unplugged,
  removing the qdev_free, making it take a VirtIODevice and calling it
  from virtio_device_exit

- adding a k->exit callback

virtio_device_exit is still overwritten, the next patches will fix that.

  virtio-pci: add device_unplugged callback

This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe
switch.  The crash happens because the ioeventfd is still set whent the
child is destroyed (destruction happens in postorder).  Then the proxy
tries to unset to ioeventfd, but the virtqueue structure that holds the
EventNotifier has been trashed in the meanwhile.  kvm_set_ioeventfd_pio
does not expect failure and aborts.

The fix is simply to move parts of uninitialization to a new
device_unplugged callback, which is called before the child is destroyed.

With a help of negative memory region priority PCI address space
is mapped underneath RAM regions effectively catching every access
to addresses not mapped by any other region.
It simplifies PCI address space mapping into system address space.

  qtest: split configuration of qtest accelerator and chardev

qtest uses the icount infrastructure to implement a test-driven vm_clock.  This
however is not necessary when using -qtest as a "probe" together with a normal
TCG-, KVM- or Xen-based virtual machine.  Hence, split out the call to
configure_icount into a new function that is called only for "-machine
accel=qtest"; and disable those commands when running with an accelerator
other than qtest.

This also fixes an assertion failure with "qemu-system-x86_64 -machine
accel=qtest" but no -qtest option.  This is a valid case, albeit somewhat
weird; nothing will happen in the VM but you'll still be able to
interact with the monitor or the GUI.

Now that qtest_init is not limited to an int(void) function, change
global variables that are not used outside qtest_init to arguments.

And finally, cleanup useless parts of include/sysemu/qtest.h.  The file
is not used at all for user-only emulation, and qtest is not available
on Win32 due to its usage of sigwait.

  split definitions for exec.c and translate-all.c radix trees

The exec.c and translate-all.c radix trees are quite different, and
the exec.c one in particular is not limited to the CPU---it can be
used also by devices that do DMA, and in that case the address space
is not limited to TARGET_PHYS_ADDR_SPACE_BITS bits.

We want to make exec.c's radix trees 64-bit wide.  As a first step,
stop sharing the constants between exec.c and translate-all.c.
exec.c gets P_L2_* constants, translate-all.c gets V_L2_*, for
consistency with the existing V_L1_* symbols.  Though actually
in the softmmu case translate-all.c is also indexed by physical
addresses...

This patch has no semantic change.

  exec: memory radix tree page level compression

At the moment, memory radix tree is already variable width, but it can
only skip the low bits of address.

This is efficient if we have huge memory regions but inefficient if we
are only using a tiny portion of the address space.

After we have built up the map, detect
configurations where a single L2 entry is valid.

We then speed up the lookup by skipping one or more levels.
In case any levels were skipped, we might end up in a valid section
instead of erroring out. We handle this by checking that
the address is in range of the resulting section.

  exec: make address spaces 64-bit wide

As an alternative to commit 818f86b (exec: limit system memory
size, 2013-11-04) let's just make all address spaces 64-bit wide.
This eliminates problems with phys_page_find ignoring bits above
TARGET_PHYS_ADDR_SPACE_BITS and address_space_translate_internal
consequently messing up the computations.

In Luiz's reported crash, at startup gdb attempts to read from address
0xffffffffffffffe6 to 0xffffffffffffffff inclusive.  The region it gets
is the newly introduced master abort region, which is as big as the PCI
address space (see pci_bus_init).  Due to a typo that's only 2^63-1,
not 2^64.  But we get it anyway because phys_page_find ignores the upper
bits of the physical address.  In address_space_translate_internal then

    diff = int128_sub(section->mr->size, int128_make64(addr));
    *plen = int128_get64(int128_min(diff, int128_make64(*plen)));

diff becomes negative, and int128_get64 booms.

The size of the PCI address space region should be fixed anyway.

Take care to do this only for new machine types, of course.

Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member
product stable in the future.  Use copies instead, and in a way that
makes it obvious that they're guest ABI.

Note that we can be trusted to keep values of member name, because
that has always been ABI.

    After changing the parameter from `NotSerialized` to `Serialized`, the
    remark is indeed gone and there is no size change.

    The remark was added in ACPICA version 20130517 [1] and gives the
    following explanation.
       If a thread blocks within the method for any reason, and another thread
      enters the method, the method will fail because an attempt will be
      made to create the same (named) object twice.
       In this case, issue a remark that the method should be marked
      serialized. ACPICA BZ 909.

  pci: fix pci bridge fw path

qemu uses "pci" as name for pci bridges in the firmware device path.
seabios expects "pci-bridge".  Result is that bootorder is broken for
devices behind pci bridges.

Some googling suggests that "pci-bridge" is the correct one.  At least
PPC-based Apple machines are using this.  See question "How do I boot
from a device attached to a PCI card" here:
        http://www.netbsd.org/ports/macppc/faq.html

So lets change qemu to use "pci-bridge" too.

  hpet: inverse polarity when pin above ISA_NUM_IRQS

According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)

We fold the emulation of this inversion inside the hpet logic.

  hpet: enable to entitle more irq pins for hpet

Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.

On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.

Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

  exec: separate sections and nodes per address space

Every address space has its own nodes and sections, but
it uses the same global arrays of nodes/section.

This limits the number of devices that can be attached
to the guest to 20-30 devices. It happens because:
 - The sections array is limited to 2^12 entries.
 - The main memory has at least 100 sections.
 - Each device address space is actually an alias to
   main memory, multiplying its number of nodes/sections.

Remove the limitation by using separate arrays of
nodes and sections for each address space.

acpi.pci,pc,memory core fixes

Most notably this includes changes to exec to support
full 64 bit addresses.

This also flushes out patches that got queued during 1.7 freeze.
There are new tests, and a bunch of bug fixes all over the place.
There are also some changes mostly useful for downstreams.

I'm also listing myself as pc co-maintainer. I'm doing this reluctantly,
but this seems to be necessary to make sure patches are not lost or delayed too
much, and posting the MAINTAINERS patch did not seem to make anyone else
volunteer.
