Similar to the case removed in commit 69c38b8 (ide/core: Remove explicit
setting of BM_STATUS_INT, 2011-05-19), the only remaining use of
add_status(..., BM_STATUS_INT) is for short PRDs.  The flag should
not be raised in this case.

58ac321135 ide: Treat read/write beyond end as invalid
The block layer fails such reads and writes just fine.  However, they
then get treated like valid operations that fail: the error action
gets executed.  Unwanted; reporting the error to the guest is the only
sensible action.

Reject them before passing them to the block layer.  This bypasses the
error action and I/O accounting.  Not quite correct for DMA, because
DMA can fail after some success, and when that happens, the part that
succeeded isn't counted.  Tolerable, because I/O accounting is an
inconsistent mess anyway.

5a18e67dfd ahci: map memory via device's address space instead of address_space_memory
In map_page() in hw/ide/ahci.c, replace cpu_physical_memory_map() and
cpu_physical_memory_unmap() with dma_memory_map() and dma_memory_unmap(),
because ahci devices should not access memory directly but via their address
space. Add an AddressSpace parameter to map_page(). In order to call
map_page(), we should pass the AHCIState.as as the AddressSpace argument.

d02f8adc6d ahci.c: mask unused flags when reading size PRDT DBC
The data byte count(DBC) read from the description information is defined for
bits 21:00. Bits 30:22 are reserved and bit 31 is the Interrupt on Completion
(I) flag.

Completion interrupts are triggered after every transaction instead of on
I-flag in QEMU. tbl_entry_size is a signed integer and improperly reading the
DBC leads to a negative offset that causes sglist allocation to fail.

a589569f2f qapi: adjust existing defines
In order to let event defines use existing types later, instead of
redefine new ones, some old type defines for spice and vnc are changed,
and BlockErrorAction is moved from block.h to qapi schema. Note that
BlockErrorAction is not merged with BlockdevOnError.

At this point, VncInfo is not made a child of VncBasicInfo, because
VncBasicInfo has mandatory fields where VncInfo makes them optional.

3e300fa6ad macio ide: Do remainder access asynchronously
The macio IDE controller has some pretty nasty magic in its implementation to
allow for unaligned sector accesses. We used to handle these accesses
synchronously inside the IO callback handler.

However, the block infrastructure changed below our feet and now it's impossible
to call a synchronous block read/write from the aio callback handler of a
previous block access.

Work around that limitation by making the unaligned handling bits also go
through our asynchronous handler.

This fixes booting Mac OS X for me.

85720d3667 macio: handle non-block ATAPI DMA transfers
Currently the macio DMA routines assume that all DMA requests are for read/write
block transfers. This is not always the case for ATAPI, for example when
requesting a TOC where the response is generated directly in the IDE buffer.

Detect these non-block ATAPI DMA transfers (where no lba is specified in the
command) and copy the results directly into RAM as indicated by the DBDMA
descriptor. This fixes CDROM access under MorphOS.

ae2158ad6c ahci: fix buffer overrun on invalid state load
CVE-2013-4526

Within hw/ide/ahci.c, VARRAY refers to ports which is also loaded.  So
we use the old version of ports to read the array but then allow any
value for ports.  This can cause the code to overflow.

There's no reason to migrate ports - it never changes.
So just make sure it matches.

bd16430777 ahci: fix sysbus support
Non-PCI AHCI support is broken due to assertion failures when trying
to convert AHCIState to a PCIDevice pointer as AHCIState can have
different container structs. Fix this by using the non-asserting object
cast and checking the returned pointer is not NULL.

The AddressSpace pointer is also being initialized to NULL and causing
dma_memory_map call to fail. Fix this by initializing to
address_space_memory for sysbus instances.

Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState
for sysbus instances.

1b7fd72955 block: rename buffer_alignment to guest_block_size
The alignment field is now set to the value that is promised to the
guest, rather than required by the host.  The next patches will make
QEMU aware of the host-provided values, so make this clear.

The alignment is also not about memory buffers, but about the sectors on
the disk, change the documentation of the field.

At this point, the field is set by the device emulation, but completely
ignored by the block layer.

04916ee9fb vt82c686: Clean up use of cannot_instantiate_with_device_add_yet
A VT82C686B southbridge has multiple functions.  We model each
function as a separate qdev.  One of them need some special wiring set
up in mips_fulong2e_init() to work: the ISA bridge at 05.0.

The IDE controller at 05.1 (via-ide) has always had
cannot_instantiate_with_device_add_yet set, but there is no obvious
reason why device_add could not work for them.  Drop it.

efec3dd631 qdev: Replace no_user by cannot_instantiate_with_device_add_yet
In an ideal world, machines can be built by wiring devices together
with configuration, not code.  Unfortunately, that's not the world we
live in right now.  We still have quite a few devices that need to be
wired up by code.  If you try to device_add such a device, it'll fail
in sometimes mysterious ways.  If you're lucky, you get an
unmysterious immediate crash.

To protect users from such badness, DeviceClass member no_user used to
make device models unavailable with -device / device_add, but that
regressed in commit 18b6dad.  The device model is still omitted from
help, but is available anyway.

Attempts to fix the regression have been rejected with the argument
that the purpose of no_user isn't clear, and it's prone to misuse.

This commit clarifies no_user's purpose.  Anthony suggested to rename
it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which
I shorten somewhat to keep checkpatch happy.  While there, make it
bool.

Every use of cannot_instantiate_with_device_add_yet gets a FIXME
comment asking for rationale.  The next few commits will clean them
all up, either by providing a rationale, or by getting rid of the use.

With that done, the regression fix is hopefully acceptable.

8464b273d6 ahci: fix win7 hang on boot
When AHCI executes an asynchronous IDE command, it checked DRDY without
checking either DRQ or BSY.  This sometimes caused interrupt to be sent
before command is actually completed.

This resulted in a race condition: if guest then managed to access the
device before command has completed, it would hang waiting for an
interrupt.
This was observed with windows 7 guests.

To fix, check for DRQ or BSY in additiona to DRDY, if set,
the command is asynchronous so delay the interrupt until
asynchronous done callback is invoked.
