5661ae6be2 target-arm: Add ULL suffix to calculation of page size
The maximum block size for AArch64 address translation is 2GB. This means
that we need a ULL suffix on our shift to avoid shifting into the sign
bit of a signed 32 bit integer.

e389be1673 target-arm: implement PD0/PD1 bits for TTBCR
Corrected handling of writes to TTBCR for ARMv8 (previously UNK/SBZP
bits are not RES0) and ARMv7 (new bits PD0/PD1 for CPUs with Security
Extensions).

Bits PD0/PD1 are now respected in get_phys_addr_v6/v5() and
get_level1_table_address.

56fdfb6106 qapi/string-output-visitor: fix bugs
in human mode, we are creating the string:

16-31 (16-31)

instead of

16-17 (10-1f)

because we forgot to pass 'true' as the human parameter on one of the
two calls to format_string.
Also, this is a worsening of quality; previously we would produce

16 (0x10)

to make it obvious which number was hex.
Fix these issues.

521b3673ac acpi: introduce TYPE_ACPI_DEVICE_IF interface
... it will be used to abstract generic ACPI bits from
device that implements ACPI interface.

ACPIOSTInfo type is used for passing-through raw _OST
event/status codes reported by guest OS to a management
layer. It lets management tools interpret values
as specified by ACPI spec if it is interested in it.

QEMU doesn't encode these values as enum, since it
doesn't need to handle them and it allows interface
to scale well without any changes in QEMU while guest
OS and management evolves in time.

5942a19040 qdev: recursively unrealize devices when unrealizing bus
When the patch was posted that became 5c21ce7 (qdev: Realize buses
on device realization, 2014-03-12), it included recursive realization
and unrealization of devices when the bus's "realized" property
was toggled.

However, due to the same old worries about recursive realization
and prerequisites not being realized yet, those hunks were dropped when
committing the patch.  Unfortunately, this causes a use-after-free bug
(easily reproduced by a PCI hot-unplug action).

Before the patch, device_unparent behaved as follows:

   for each child bus
     unparent bus ----------------------------.
     | for each child device                  |
     |   unparent device ---------------.     |
     |   | unrealize device             |     |
     |   | call dc->unparent            |     |
     |   '-------------------------------     |
     '----------------------------------------'
   unrealize device

After the patch, it behaves as follows instead:

   unrealize device --------------------.
   | for each child bus                 |
   |   unrealize bus               (A)  |
   '------------------------------------'
   for each child bus
     unparent bus ----------------------.
     | for each child device            |
     |   unrealize device          (B)  |
     |   call dc->unparent              |
     '----------------------------------'

At the step marked (B) the device might use data from the bus that is
not available anymore due to step (A).

To fix this, we need to unrealize devices before step (A).  To sidestep
concerns about recursive realization, only do recursive unrealization
and leave the "value && !bus->realized" case as it is.

The resulting flow is:

   for each child bus
     unrealize bus ---------------------.
     | for each child device            |
     |   unrealize device          (B)  |
     | call bc->unrealize          (A)  |
     '----------------------------------'
   unrealize device
   for each child bus
     unparent bus ----------------------.
     | for each child device            |
     |   unparent device                |
     '----------------------------------'

where everything is "powered down" before it is unassembled.

options and some information regarding how it relates to options -m and
-smp. This commit fills in the missing text.

2b631ec255 NUMA: check if the total numa memory size is equal to ram_size
If the total number of the assigned numa nodes memory is not
equal to the assigned ram size, it will write the wrong data
to ACPI table, then the guest will ignore the wrong ACPI table
and recognize all memory to one node. It's buggy, we should
check it to ensure that we write the right data to ACPI table.
