vvfat: Use opened node as backing file
We should not try to assign a not yet opened node as the backing file,
because as soon as the permission system is added it will fail. The
just added bdrv_new_open_driver() function is the right tool to open a
file with an internal driver, use it.
In case anyone wonders whether that magic fake backing file to trigger a
special action on 'commit' actually works today: No, not for me. One
reason is that we've been adding a raw format driver on top for several
years now and raw doesn't support commit. Other reasons include that the
backing file isn't writable and the driver doesn't support reopen, and
it's also size 0 and the driver doesn't support bdrv_truncate. All of
these are easily fixable, but then 'commit' ended up in an infinite loop
deep in the vvfat code for me, so I thought I'd best leave it alone. I'm
not really sure what it was supposed to do anyway.

block: Attach bs->file only during .bdrv_open()
The way that attaching bs->file worked was a bit unusual in that it was
the only child that would be attached to a node which is not opened yet.
Because of this, the block layer couldn't know yet which permissions the
driver would eventually need.
This patch moves the point where bs->file is attached to the beginning
of the individual .bdrv_open() implementations, so drivers already know
what they are going to do with the child. This is also more consistent
with how driver-specific children work.
For a moment, bdrv_open() gets its own BdrvChild to perform image
probing, but instead of directly assigning this BdrvChild to the BDS, it
becomes a temporary one and the node name is passed as an option to the
drivers, so that they can simply use bdrv_open_child() to create another
reference for their own use.
This duplicated child for (the not opened yet) bs is not the final
state, a follow-up patch will change the image probing code to use a
BlockBackend, which is completely independent of bs.

When using file system that does not support fallocate() (e.g. NFS <

one pwrite() per block.

pread64(9, "\0", 1, 4095) = 1
pwrite64(9, "\0", 1, 4095) = 1

...
pwrite64(9, "\0", 1, 4095) = 1
pwrite64(9, "\0", 1, 8191) = 1
This happens because posix_fallocate is checking if each block is
allocated before writing a byte to the block, and when truncating the
file before preallocation, all blocks are unallocated.

hw/ppc/spapr: Check for valid page size when hot plugging memory
On POWER, the valid page sizes that the guest can use are bound
to the CPU and not to the memory region. QEMU already has some
fancy logic to find out the right maximum memory size to tell
it to the guest during boot (see getrampagesize() in the file
target/ppc/kvm.c for more information).
However, once we're booted and the guest is using huge pages
already, it is currently still possible to hot-plug memory regions
that does not support huge pages - which of course does not work
on POWER, since the guest thinks that it is possible to use huge
pages everywhere. The KVM_RUN ioctl will then abort with -EFAULT,
QEMU spills out a not very helpful error message together with
a register dump and the user is annoyed that the VM unexpectedly
died.
To avoid this situation, we should check the page size of hot-plugged
DIMMs to see whether it is possible to use it in the current VM.
If it does not fit, we can print out a better error message and
refuse to add it, so that the VM does not die unexpectely and the
user has a second chance to plug a DIMM with a matching memory
backend instead.

hw/net/spapr_llan: 6 byte mac address device tree entry
The spapr-vlan device in QEMU has always presented it's MAC address in
the device tree as an 8 byte value, even though PAPR requires it to be
6 bytes. This is because, at the time, AIX required the value to be 8
bytes. However, modern versions of AIX support the (correct) 6
byte value so they no longer require the workaround.
It would be neatest to always provide a 6 byte value but that would
cause a problem with old Linux kernel ibmveth drivers, so the old 8
byte value is still presented when necessary.
Since commit
13f85203e (3.10, May 2013) the driver has been able to
handle 6 or 8 byte addresses so versions after that don't need to be
considered specially.
Drivers from kernels before that can also handle either type of
address, but not always:
* If the first byte's lowest bits are 10, the address must be 6 bytes.
* Otherwise, the address must be 8 bytes.
(The two bits in question are significant in a MAC address: they
indicate a locally-administered unicast address.)
So to maintain compatibility the old 8 byte value is presented when
the lowest two bits of the first byte are not 10.

hw/mips: MIPS Boston board support
Introduce support for emulating the MIPS Boston development board. The
Boston board is built around an FPGA & 3 PCIe controllers, one of which
is connected to an Intel EG20T Platform Controller Hub. It is used
during the development & debug of new CPUs and the software intended to
run on them, and is essentially the successor to the older MIPS Malta
board.
This patch does not implement the EG20T, instead connecting an already
supported ICH-9 AHCI controller. Whilst this isn't accurate it's enough
for typical stock Boston software (eg. Linux kernels) to work with hard
disks given that both the ICH-9 & EG20T implement the AHCI
specification.
Boston boards typically boot kernels in the FIT image format, and this
patch will treat kernels provided to QEMU as such. When loading a kernel
directly, the board code will generate minimal firmware much as the
Malta board code does. This firmware will set up the CM, CPC & GIC
register base addresses then set argument registers & jump to the kernel
entry point. Alternatively, bootloader code may be loaded using the bios
argument in which case no firmware will be generated & execution will
proceed from the start of the boot code at the default MIPS boot
exception vector (offset 0x1fc00000 into (c)kseg1).
Currently real Boston boards are always used with FPGA bitfiles that
include a Global Interrupt Controller (GIC), so the interrupt
configuration is only defined for such cases. Therefore the board will
only allow use of CPUs which implement the CPS components, including the
GIC, and will otherwise exit with a message.

whether the CPU is 64 bit or which architecture revision it implements.

hw/mips_gic: Update pin state on mask changes
If the GIC interrupt mask is changed by a write to the smask (set mask)
or rmask (reset mask) registers, we need to re-evaluate the state of the
pins/IRQs fed to the CPU. Without doing so we risk leaving a pin high
despite the interrupt that led to that state being masked, or losing
interrupts if an already pending interrupt is unmasked.

create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi.
For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU
create 25 of them.
lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and
currently has no maintainer in QEMU. megasas is a better choice,
except with old OSes that lack drivers. virtio-scsi is a much better
choice when you have a driver, but only (newish) Linux comes with one
in the box. There is no good default that works for all guests.

deprecating -drive if=scsi.
