It is not necessary to munmap an area before remapping it with MAP_FIXED;
if the memory region specified by addr and len overlaps pages of any
existing mapping, then the overlapped part of the existing mapping will
be discarded.
On the other hand, if QEMU does munmap the pages, there is a small
probability that another mmap sneaks in and catches the just-freed
portion of the address space. In effect, munmap followed by
mmap(MAP_FIXED) is a use-after-free error, and Coverity flags it
as such. Fix it.

IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B0000.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.
This removes CPU_POWERPC_POWER5P_v00 definition and changes

it adds an optional 4 byte emerg_wr field.
As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.
As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.
Long terms we probably want something along the lines
of virtio_net_set_config_size.

following a464982499, it's now possible for
there to be attempts to take the BQL before CPUs have been realized in
cases where a machine model inits peripherals before the first CPU.
BQL lock aquisition kicks the first_cpu, leading to a segfault if this
happens pre-realize. Guard the CPU kick routine to perform no action for
a CPU that doesn't exist or doesn't have a thread yet.
There was a fix to this with commit
6b49809c59, but the check there misses
the case where the CPU has been inited and not realized. Strengthen the
check to make sure that the first_cpu has a thread (i.e. it is
realized) before allowing the kick.

If the guest programs a sufficiently large timeout value an integer
overflow can occur in i6300esb_restart_timer(). e.g. if the maximum
possible timer preload value of 0xfffff is programmed then we end up with
the calculation:
timeout = get_ticks_per_sec() * (0xfffff << 15) / 33000000;
get_ticks_per_sec() returns 1000000000 (10^9) giving:
10^9 * (0xfffff * 2^15) == 0x1dcd632329b000000 (65 bits)
Obviously the division by 33MHz brings it back under 64-bits, but the
overflow has already occurred.
Since signed integer overflow has undefined behaviour in C, in theory this
could be arbitrarily bad. In practice, the overflowed value wraps around
to something negative, causing the watchdog to immediately expire, killing
the guest, which is still fairly bad.
The bug can be triggered by running a Linux guest, loading the i6300esb
driver with parameter "heartbeat=2046" and opening /dev/watchdog. The
watchdog will trigger as soon as the device is opened.
This patch corrects the problem by using muldiv64(), which effectively
allows a 128-bit intermediate value between the multiplication and
division.

The IO operations for the i6300esb watchdog timer are marked as
DEVICE_NATIVE_ENDIAN. This is not correct, and - as a PCI device - should
be DEVICE_LITTLE_ENDIAN.
This allows i6300esb to work on ppc targets (yes, using an Intel ICH
derived device on ppc is a bit odd, but the driver exists on the guest
and there's no more obviously suitable watchdog device).
