Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE,
hence --enable-debug disables optimization. This is not acceptable
for ROMs, which should override CFLAGS to force inclusion of -O2.
Second, PE stores global constructors and destructors using the
following linker script snippet:
___CTOR_LIST__ = .; __CTOR_LIST__ = . ;
LONG (-1);*(.ctors); *(.ctor); *(SORT(.ctors.*)); LONG (0);
___DTOR_LIST__ = .; __DTOR_LIST__ = . ;
LONG (-1); *(.dtors); *(.dtor); *(SORT(.dtors.*)); LONG (0);
The LONG directives cause the .img files to be 16 bytes too large;
the recently added check to signrom.py catches this. To fix this,
replace -T and -e options with a linker script.

When calling make with a CFLAGS=.. argument, the -g/-O filter is not
applied, which may result with build failure with ASAN for example. It
could be solved with an 'override' directive on CFLAGS, but that would
actually prevent setting different CFLAGS manually.
Instead, filter the CFLAGS argument from the top-level Makefile (so
you could still call make with a different CFLAGS argument on a
rom/Makefile manually)

Recent GCC compiles linuxboot_dma.c to 921 bytes, while CentOS 6 needs
1029 and clang needs 1527. Because the size of the ROM, rounded to the
next 512 bytes, must match, this causes the API to break between a <1K
ROM and one that is bigger.
We want to make the ROM 1.5 KB in size, but it's better to make clang
produce leaner ROMs, because currently it is worryingly close to the limit.
To fix this prevent clang's happy inlining (which -Os cannot prevent).
This only requires adding a noinline attribute.
Second, the patch makes sure that the ROM has enough padding to prevent
ABI breakage on different compilers. The size is now hardcoded in the file
that is passed to signrom.py, as was the case before commit 6f71b77
("scripts/signrom.py: Allow option ROM checksum script to write the size
header.", 2016-05-23); signrom.py however will still pad the input to
the requested size. This ensures that the padding goes beyond the
next multiple of 512 if necessary, and also avoids the need for
-fno-toplevel-reorder which clang doesn't support. signrom.py can then
error out if the requested size is too small for the actual size of the
compiled ROM.

Since aa5cb7f5e, the chardevs are being cleaned up when leaving qemu,
before the atexit() handlers. audio_cleanup() may use the monitor to
notify of changes. For compatibility reasons, let's clean up audio
before the monitor so it keeps emitting monitor events.
The audio_atexit() function is made idempotent (so it can be called
multiple times), and renamed to audio_cleanup(). Since coreaudio
backend is using a 'isAtexit' code path, change it to check
audio_is_cleaning_up() instead, so the path is taken during normal
exit.

After 0965a41, mirror starts several smaller requests in parallel, when

When a TCE table (sPAPR IOMMU context) is in disabled state (which is true
by default for the 64-bit window), it has tcet->nb_table == 0 and
tcet->table == NULL. However, on system reset, spapr_tce_reset() executes,
which unconditionally calls
memset(tcet->table, 0, table_size);
We get away with this in practice, because it's a zero length memset(),
but memset() on a NULL pointer is undefined behaviour, so we should not
call it in this case.

Prior to c8721d3 "spapr: Error out when CPU hotplug is attempted on older
pseries machines", attempting to use query-hotpluggable-cpus on pseries-2.6
and earlier machine types would SEGV.
That change fixed that, but due to some unexpected interactions in init
order and a brown-paper-bag worthy failure to test, it accidentally
disabled query-hotpluggable-cpus for all pseries machine types, including
the current one which should allow it.
In fact, query_hotpluggable_cpus needs to be non-NULL when and only when
the dr_cpu_enabled flag in sPAPRMachineClass is set, which makes
dr_cpu_enabled itself redundant.
This patch removes dr_cpu_enabled, instead directly setting
query_hotpluggable_cpus from the machine class_init functions, and using
that to determine the availability of CPU hotplug when necessary.

Follow John Snow recommendation:
Everywhere else ncq_err is used, it is accompanied by a list cleanup
except for ncq_cb, which is the case you are fixing here.
Move the sglist destruction inside of ncq_err and then delete it from
the other two locations to keep it tidy.
Call dma_buf_commit in ide_dma_cb after the early return. Though, this
is also a little wonky because this routine does more than clear the
list, but it is at the moment the centralized "we're done with the
sglist" function and none of the other side effects that occur in
dma_buf_commit will interfere with the reset that occurs from
ide_restart_bh, I think

Clear the list when finalizing. The list is created during realize with

Make sure the connection data got freed when closing the chardev, to

Rather than rely on recursion during the middle of register allocation,
lower indirect registers to loads and stores off the indirect base into
plain temps.
For an x86_64 host, with sufficient registers, this results in identical
code, modulo the actual register assignments.
For an i686 host, with insufficient registers, this means that temps can
be (temporarily) spilled to the stack in order to satisfy an allocation.
This as opposed to the possibility of not being able to spill, to allocate
a register for the indirect base, in order to perform a spill.

We have three qtest tests which have test names ending with "error".
This is awkward because the output of verbose test runs looks like
/crypto/task/error: OK
/crypto/task/thread_error: OK
which gives false positives if you are grepping build logs for
errors by looking for "error:". Since there are only three tests
with this problem, just rename them all to 'failure' instead.
