The local spice renderer assumes the primary surface is located at the
start of the "ram" bar. This used to be a requirement in qxl hardware
revision 1. In revision 2+ this is relaxed. Nevertheless guest drivers
continued to use the traditional location, for historical and backward
compatibility reasons. The qxl kms driver doesn't though as it depends
on qxl revision 4+ anyway.
Result is that local rendering is hosed for recent linux guests, you'll
get pixel garbage with non-spice ui (gtk, sdl, vnc) and when doing
screendumps. Fix that by doing a proper mapping of the guest-specified
memory location.
Now that the memory subsystem is propagating the endianness correctly,
the ne2000 device should have its I/O ports marked as LITTLE_ENDIAN, as
PCI devices are little endian.
This makes the ne2000 NIC to work again on PowerPC.

Secondly it's always more efficient to avoid copying the guest

pseries: Fix stalls on hypervisor virtual console
A number of users are reporting stalls when using the pseries
hypervisor virtual console.
A simple test case is to paste 15 or 17 characters at a time
into the console. Pasting 15 characters at a time works fine
but pasting 17 characters hangs for a random amount of time.
Other activity (network, qemu monitor etc) unblocks it.
If qemu-char tries to send more than 16 characters at once,
vty_can_receive returns false. At this point we have to
wait for the guest to consume that output. Everything is good
so far.
The problem occurs when the the guest does consume the output.
We need to signal back to the qemu-char layer that we are

qemu-char: fix infinite recursion connecting to monitor pty
Since commit bd5c51e (qemu-char: don't issue CHR_EVENT_OPEN in a BH), an
infinite recursion occurs when putting the monitor on a pty (-monitor
pty) and connecting a terminal to the slave port.
This is because of the qemu_chr_be_event(s, CHR_EVENT_OPENED) added to
qemu_chr_be_generic_open(). This event is captured by monitor_event()
which prints a welcome message to the character device. The flush of
that welcome message retriggers another open event in pty_chr_state()
because it checks s->connected, but only sets it to 1 after calling
qemu_chr_be_generic_open().
I've fixed this by setting s->connected = 1 before the call to
qemu_chr_be_generic_open() instead of after, so that the recursive
pty_chr_state() doesn't call it again.

If the user is listening on '[::]', then we will not have a opened a device
yet and have no way of verifying if the device is RoCE or not.
In this case, the source VM will throw an error for ALL types of
connections (both IPv4 and IPv6) if the destination machine does not have
a regular infiniband network available for use.
The only way to gaurantee that an error is thrown for broken kernels is
for the management software to choose a *specific* interface at bind time
and validate what time of hardware it is.
Unfortunately, this puts the user in a fix:
If the source VM connects with an IPv4 address without knowing that the
destination has bound to '[::]' the migration will unconditionally fail
unless the management software is not explicitly listening on the the IPv4
address while using a RoCE-based device.
If the source VM connects with an IPv6 address, then we're OK because we can
throw an error on the source (and similarly on the destination).
But in mixed environments, this will be broken for a while until it is fixed
inside linux.
We do provide a *tiny* bit of help in mixed environments, though in this patch:
We can list all of the devices in the system and check to see if all the
devices are RoCE or Infiniband.
If we detect that we have a *pure* RoCE environment, then we can safely
thrown an error even if the management sofware has specified '[::]' as the
bind address.
However, if there is are multiple hetergeneous devices, then we cannot make
this assumption and the user just has to be sure they know what they are doing.

qemu-option: Guard against qemu_opts_set_defaults() misuse
Commit 6d4cd40 fixed qemu_opts_set_defaults() for an existing corner
case, but broke it for another one that can't be reached in current
code.
Quote from its commit message:
I believe [opts_parse()] attempts to do the following:
If options don't yet exist, create new options
Else, if defaults, modify the existing options
Else, if list->merge_lists, modify the existing options
Else, fail
The only caller that passes true for defaults is
qemu_opts_set_defaults().
The commit message then claims:
A straightforward call of qemu_opts_create() does exactly that.
Wrong. When !list->merge_lists, and the option string doesn't contain
id=, and options without ID exist, then we don't actually modify the
existing options, we create new ones.
Not reachable, because we never pass lists with !list->merge_lists to
qemu_opts_set_defaults().
Guard against possible (if unlikely) future misuse with assert().

The new poke_file function sets bytes at an offset in a file given a
printf-style format string. It can be used to corrupt an image file for
test coverage of error paths.

target-mips: fix decoding of microMIPS POOL32Axf instructions
Fix incorrect assumption that DSP and non-DSP versions of the following
instructions have the same encoding:
MULT, MULTU, MADD, MADDU, MSUB, MSUBU, MFHI, MFLO, MTHI, MTLO.
Correct the existing (non-DSP) instructions and add DSP equivalents.

sheepdog: add missing .bdrv_has_zero_init
Commit 3ac21627 changed the behaviour of bdrv_has_zero_init() to default
to 0. In the review for Sheepdog it turned out that enabling it is safe,
so that commit updated one BlockDriver definition of sheepdog to use
bdrv_has_zero_init_1, missed however that there are more BlockDrivers in
the driver. Fix these now.

qemu-img: Error out for excess arguments
Don't silently ignore excess arguments at the end of the command line,
but error out instead. This can catch typos like 'resize test.img + 1G',
which doesn't increase the image size by 1G as intended, but truncates
the image to 1G. Even for less dangerous commands, the old behaviour is
confusing.

semaphore: fix a hangup problem under load on NetBSD hosts.
Fix following bugs in "fallback implementation of counting semaphores
with mutex+condvar" added in c166cb72f1676855816340666c3b618beef4b976:
- waiting threads are not restarted properly if more than one threads
are waiting unblock signals in qemu_sem_timedwait()
- possible missing pthread_cond_signal(3) calls when waiting threads
are returned by ETIMEDOUT
- fix an uninitialized variable
The problem is analyzed by and fix is provided by Noriyuki Soda.
Also put additional cleanup suggested by Laszlo Ersek:
- make QemuSemaphore.count unsigned (it won't be negative)
- check a return value of in pthread_cond_wait() in qemu_sem_wait()
