fad7fb9ccd8013ea03 ("Add IPv6 support to the TFTP code")
refactored some common code for preparing the mbuf into a new
function called tftp_prep_mbuf_data(). One part of this common
code is to do a "memset(m->m_data, 0, m->m_size);" for the related
buffer first. However, at two spots, the memset() was not removed
from the calling function, so it currently done twice in these code

spapr: drop reference on child object during core realization
When a core is being realized, we create a child object for each thread
of the core.
The child is first initialized with object_initialize() which sets its ref
count to 1, and then added to the core with object_property_add_child()
which bumps the ref count to 2.
When the core gets released, object_unparent() decreases the ref count to 1,
and we g_free() the object: we hence loose the reference on an unfinalized
object. This is likely to cause random crashes.
Let's drop the extra reference as soon as we don't need it, after the
thread is added to the core.

Eliminate redundant and incorrect booke206_page_size_to_tlb function

exported definition from e500.c
Defect analysis:
The booke206_page_size_to_tlb function in e500.c was updated in commit
2bd9543 "ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to
reflect a change in the definition of MAS1_TSIZE_SHIFT from 8
(corresponding to a min TLB page size of 4kb) to a value of 7 (TLB
page size 2k). The booke206_page_size_to_tlb() function defined in
ppce500_spin.c was never updated to reflect the change in
MAS1_TSIZE_SHIFT.
In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html,
Scott Wood suggested this "root cause" explanation:
SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the
SW> same time as the patch that added this code, which is probably why
SW> adjusting it got missed. Commit
2bd9543cd3 did update the

vfio/pci: Hide SR-IOV capability
The kernel currently exposes the SR-IOV capability as read-only
through vfio-pci. This is sufficient to protect the host kernel, but
has the potential to confuse guests without further virtualization.
In particular, OVMF tries to size the VF BARs and comes up with absurd
results, ending with an assert. There's not much point in adding
virtualization to a read-only capability, so we simply hide it for
now. If the kernel ever enables SR-IOV virtualization, we should
easily be able to test it through VF BAR sizing or explicit flags.

qapi: Fix memleak in string visitors on int lists
Commit
7f8f9ef1 introduced the ability to store a list of
integers as a sorted list of ranges, but when merging ranges,
it leaks one or more ranges. It was also using range_get_last()
incorrectly within range_compare() (a range is a start/end pair,
but range_get_last() is for start/len pairs), and will also
mishandle a range ending in UINT64_MAX (remember, we document
that no range covers 2**64 bytes, but that ranges that end on
UINT64_MAX have end < begin).
The whole merge algorithm was rather complex, and included
unnecessary passes over data within glib functions, and enough
indirection to make it hard to easily plug the data leaks.
Since we are already hard-coding things to a list of ranges,
just rewrite the thing to open-code the traversal and
comparisons, by making the range_compare() helper function give
us an answer that is easier to use, at which point we avoid the
need to pass any callbacks to g_list_*(). Then by reusing
range_extend() instead of duplicating effort with range_merge(),
we cover the corner cases correctly.
Drop the now-unused range_merge() and ranges_can_merge().
Doing this lets test-string-{input,output}-visitor pass under
valgrind without leaks.

qapi: Simplify use of range.h
Calling our function g_list_insert_sorted_merged is a misnomer,
since we are NOT writing a glib function. Furthermore, we are
making every caller pass the same comparator function of
range_merge(): any caller that would try otherwise would break
in weird ways since our internal call to ranges_can_merge() is
hard-coded to operate only on ranges, rather than paying
attention to the caller's comparator.
Better is to fix things so that callers don't have to care about
our internal comparator, by picking a function name and updating
the parameter type away from a gratuitous use of void*, to make
it obvious that we are operating specifically on a list of ranges
and not a generic list. Plus, refactoring the code here will
make it easier to plug a memory leak in the next patch.

qapi: Fix crash on missing alternate member of QAPI struct
If a QAPI struct has a mandatory alternate member which is not
present on input, the input visitor reports an error for the
missing alternate without setting the discriminator, but the
cleanup code for the struct still tries to use the dealloc
visitor to clean up the alternate.
Commit
dbf11922 changed visit_start_alternate to set *obj to NULL
when an error occurs, where it was previously left untouched.
Thus, before the patch, the dealloc visitor is blindly trying to
cleanup whatever branch corresponds to (*obj)->type == 0 (that is,
QTYPE_NONE, because *obj still pointed to zeroed memory), which
selects the default branch of the switch and sets an error, but
this second error is ignored by the way the dealloc visitor is
used; but after the patch, the attempt to switch dereferences NULL.
When cleaning up after a partial object parse, we specifically
check for !*obj after visit_start_struct() (see gen_visit_object());
doing the same for alternates fixes the crash. Enhance the testsuite
to give coverage for both missing struct and missing alternate
members.
Also add an abort - we expect visit_start_alternate() to either set an
error or to set (*obj)->type to a valid QType that corresponds to
actual user input, and QTYPE_NONE should never be reachable from valid
input. Had the abort() been in place earlier, we might have noticed
the dealloc visitor dereferencing bogus zeroed memory prior to when
commit
dbf11922 forced our hand by setting *obj to NULL and causing a
fault.
Test case:
{'execute':'blockdev-add', 'arguments':{'options':{'driver':'raw'}}}
The choice of 'driver':'raw' selects a BlockdevOptionsGenericFormat
struct, which has a mandatory 'file':'BlockdevRef' in QAPI. Since
'file' is missing as a sibling of 'driver', this should report a
graceful error rather than fault. After this patch, we are back to:
{"error": {"class": "GenericError", "desc": "Parameter 'file' is missing"}}

vl: smp_parse: fix regression
Commit
0544edd88a "vl: smp_parse: cleanups" regressed any -smp
config that left either cores or threads unspecified, and specified
a topology supporting more cpus than the given online cpus. The
correct way to calculate the missing parameter would be to use
maxcpus, but it's too late to change that now. Restore the old
way, which is to calculate it with the online cpus (as is still
done), but then, if the result is zero, just set it to one.
