The ACPI Generic Event Device (GED) is a hardware-reduced specific
device[ACPI v6.1 Section 5.6.9] that handles all platform events,
including the hotplug ones. This patch generates the AML code that
defines GEDs.
Platforms need to specify their own GED Event bitmap to describe
what kind of events they want to support through GED. Also this
uses a a single interrupt for the GED device, relying on IO
memory region to communicate the type of device affected by the
interrupt. This way, we can support up to 32 events with a unique
interrupt.
This supports only memory hotplug for now.

Since 9458a9a1df, all readers of the dirty bitmaps wait
for the rcu lock, which means that they wait until the end
of any executing TranslationBlock.
As a consequence, there is no need for the actual access
to happen in between the _prepare and _complete. Therefore,
we can improve things by merging the two functions into
notdirty_write and dropping the NotDirtyInfo structure.
In addition, the only users of notdirty_write are in cputlb.c,
so move the merged function there. Pass in the CPUIOTLBEntry

When iothreads are in use, the failure to grab the aio context results
in an assertion failure when trying to unlock things during blk_unref,
when trying to unlock a mutex that was not locked. In short, all
calls to nbd_export_put need to done while within the correct aio
context. But since nbd_export_put can recursively reach itself via
nbd_export_close, and recursively grabbing the context would deadlock,
we can't do the context grab directly in those functions, but must do
so in their callers.
Hoist the use of the correct aio_context from nbd_export_new() to its
caller qmp_nbd_server_add(). Then tweak qmp_nbd_server_remove(),
nbd_eject_notifier(), and nbd_esport_close_all() to grab the right
context, so that all callers during qemu now own the context before
nbd_export_put() can call blk_unref().
Remaining uses in qemu-nbd don't matter (since that use case does not
support iothreads).

Cleaning up offline XenDevice objects directly in
xen_device_backend_changed() is dangerous as xen_device_unrealize() will
modify the watch list that is being walked. Even the QLIST_FOREACH_SAFE()
used in notifier_list_notify() is insufficient as *two* notifiers (for
the frontend and backend watches) are removed, thus potentially rendering
the 'next' pointer unsafe.
The solution is to use the XenBus backend_watch handler to do the clean-up
instead, as it is invoked whilst walking a separate watch list.
This patch therefore adds a new 'inactive_devices' list to XenBus, to which
offline devices are added by xen_device_backend_changed(). The XenBus
backend_watch registration is also changed to not only invoke
xen_bus_enumerate() but also a new xen_bus_cleanup() function, which will
walk 'inactive_devices' and perform the necessary actions.
For safety an extra 'online' check is also added to xen_bus_type_enumerate()
to make sure that no attempt is made to create a new XenDevice object for a
backend that is offline.
NOTE: This patch also includes some cosmetic changes:
- substitute the local variable name 'backend_state'
in xen_bus_type_enumerate() with 'state', since there
is no ambiguity with any other state in that context.
- change xen_device_state_is_active() to
xen_device_frontend_is_active() (and pass a XenDevice directly)
since the state tests contained therein only apply to a frontend.
- use 'state' rather then 'xendev->backend_state' in
xen_device_backend_changed() to shorten the code.

This is so I2C devices can be found in the ACPI namespace. Currently
that's only IPMI, but devices can be easily added now.
Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.
Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.

This contains quite a few patches that I'd like to target for 4.2.
They're mostly emulation fixes for the sifive_u board, which now much
more closely matches the hardware and can therefor run the same fireware
as what gets loaded onto the board. Additional user-visible
improvements include:
* support for loading initrd files from the command line into Linux, via
/chosen/linux,initrd-{start,end} device tree nodes.
* The conversion of LOG_TRACE to trace events.
* The addition of clock DT nodes for our uart and ethernet.
This also includes some preliminary work for the H extension patches,
but does not include the H extension patches as I haven't had time to
review them yet.
This passes my OE boot test on 32-bit and 64-bit virt machines, as well
as a 64-bit upstream Linux boot on the sifive_u machine. It has been
fixed to actually pass "make check" this time.
Changes since v2 (never made it to the list):
* Sets the sifive_u machine default core count to 2 instead of 5.
Changes since v1 <20190910190513.21160-1-palmer@sifive.com>:
* Sets the sifive_u machine default core count to 5 instead of 1, as
it's impossible to have a single core sifive_u machine.

"qemu/cutils.h" contains various qemu_strtosz_*() functions
useful to convert strings to size. It seems natural to have
the opposite usage (from size to string) there too.
The function definition is already in util/cutils.c.

In the past we did not have a model for PRCI, hence two handcrafted
clock nodes ("/soc/ethclk" and "/soc/uartclk") were created for the
purpose of supplying hard-coded clock frequencies. But now since we
have added the PRCI support in QEMU, we don't need them any more.

At present the GEM support in sifive_u machine is seriously broken.
The GEM block register base was set to a weird number (0x100900FC),
which for no way could work with the cadence_gem model in QEMU.
Not like other GEM variants, the FU540-specific GEM has a management
block to control 10/100/1000Mbps link speed changes, that is mapped
to 0x100a0000. We can simply map it into MMIO space without special
handling using create_unimplemented_device().
Update the GEM node compatible string to use the official name used
by the upstream Linux kernel, and add the management block reg base
& size to the <reg> property encoding.
Tested with upstream U-Boot and Linux kernel MACB drivers.
