e1000: cleanup process_tx_desc
Coverity complains about two overruns in process_tx_desc(). The
complaints are false positives, but we might as well eliminate
them. The problem is that "hdr" is defined as an unsigned int,
but then used to offset an array of size 65536, and another of
size 256 bytes. hdr will actually never be greater than 255
though, as it's assigned only once and to the value of
tp->hdr_len, which is an uint8_t. This patch simply gets rid of
hdr, replacing it with tp->hdr_len, which makes it consistent
with all other tp member use in the function.

On PPC, we don't support MP state. So far it's not necessary and I'm
not convinced yet that we really need to support it ever.
However, the current idle logic in QEMU assumes that an in-kernel PIC
also means we support MP state. This assumption is not true anymore.
Let's split up the two cases into two different variables. That way
PPC can expose an in-kernel PIC, while not implementing MP state.

qemu-char: Fix ID reuse after chardev-remove for qapi-based init
Commit 2c5f488 introduced qapi-based character device initialization
as a new code path in qemu_chr_new_from_opts(). Unfortunately, it
failed to store parameter opts in the new chardev. Therefore,
qemu_chr_delete() doesn't delete it. Even though the device is gone,
its options linger, and any attempt to create another one with the

Fixing this meant that using bx as the entry index doesn't work any

block: change default of .has_zero_init to 0
.has_zero_init defaults to 1 for all formats and protocols.
this is a dangerous default since this means that all
new added drivers need to manually overwrite it to 0 if
they do not ensure that a device is zero initialized
after bdrv_create().
if a driver needs to explicitly set this value to
1 its easier to verify the correctness in the review process.
during review of the existing drivers it turned out
that ssh and gluster had a wrong default of 1.
both protocols support host_devices as backend
which are not by default zero initialized. this
wrong assumption will lead to possible corruption
if qemu-img convert is used to write to such a backend.
vpc and vmdk also defaulted to 1 altough they support
fixed respectively flat extends. this has to be addresses
in separate patches. both formats as well as the mentioned
ssh and gluster are turned to the default of 0 with this
patch for safety.
a similar problem with the wrong default existed for
iscsi most likely because the driver developer did
oversee the default value of 1.

cpu: Guard cpu_{save,load}() definitions
A few targets already managed to implement cpu_save() and cpu_load()
without defining CPU_SAVE_VERSION that causes them to be registered.
Guard the prototypes with CPU_SAVE_VERSION to avoid this happening again
until all targets are converted to VMState (or QIDL).

target-openrisc: Register VMStateDescription for OpenRISCCPU
Since commit
e67db06e9f6d7e514ee2a9b9b769ecd42977f6fb (target-or32: Add
target stubs and QOM cpu) a VMStateDescription existed, but
CPU_SAVE_VERSION was not set, so it was never registered.
Drop cpu_{save,load}() and register VMStateDescription via DeviceState.
Use a version_id of 1 and specify minimum versions as well.

target-alpha: Register VMStateDescription for AlphaCPU
Commit
b758aca1f6cdb175634812b79f5560c36c902d00 (target-alpha: Enable
the alpha-softmmu target.) introduced cpu_{save,load}() functions but
didn't define CPU_SAVE_VERSION, so they were never registered.
Drop cpu_{save,load}() and register the VMStateDescription via DeviceClass.
This operates on the AlphaCPU object instead of CPUAlphaState.
