987fec54e1 gtk: drop gtk_widget_set_double_buffered call
Dunno why it is here.  Removing it seems to have no ill side effects.
It is depricated in 3.14+.  In some cases it has no effect since 3.10
according to the docs:

1735fe1edb vmware-vga: use vmsvga_verify_rect in vmsvga_update_rect
Switch vmsvga_update_rect over to use vmsvga_verify_rect.  Slight change
in behavior:  We don't try to automatically fixup rectangles any more.
In case we find invalid update requests we'll do a full-screen update
instead.

83afa38eb2 vmware-vga: CVE-2014-3689: turn off hw accel
Quick & easy stopgap for CVE-2014-3689:  We just compile out the
hardware acceleration functions which lack sanity checks.  Thankfully
we have capability bits for them (SVGA_CAP_RECT_COPY and
SVGA_CAP_RECT_FILL), so guests should deal just fine, in theory.

Subsequent patches will add the missing checks and re-enable the
hardware acceleration emulation.

e218052f92 aio / timers: De-document -clock
Commit 6d32717 "aio / timers: Remove alarm timers" has issues:

1. It silently ignores -clock for backward compatibility.
Incompatible change: -clock help no longer terminates the program.
Tolerable.

2. Failed to update option documentation.  In particular, -help still
advises users to try -clock help for available timers.  Drop all
documentation on -clock.

3. The 'query-alarm-clock' example in docs/writing-commands.txt no
longer works, and needs to be redone.  Can't do that right now, so I
just stick in a FIXME.

024d9adc79 hw/scsi/virtio-scsi.c: fix the "type" use error in virtio_scsi_handle_ctrl
The local variable "type" in virtio_scsi_handle_ctl represents the tmf
command type from the guest and it has the same meaning as the
req->req.tmf.type. However, before the invoking of virtio_scsi_parse_req
the req->req.tmf.type doesn't has the correct value(just initialized to
zero). Therefore, we need to use the "type" variable to judge the case.

817ef04db2 Make qemu_shutdown_requested signal-safe
qemu_shutdown_requested may be interrupted by qemu_system_killed. If the
latter sets shutdown_requested after qemu_shutdown_requested has read it
but before it was cleared, the shutdown event is lost. Fix this by using
atomic_xchg.

This provides a different fix for the problem which commit 15124e142
attempts to deal with. That commit breaks use of ^C to drop into gdb,
and so this approach is better (and 15124e142 can be reverted).

14e5f10607 target-arm: Correct sense of the DCZID DZP bit
The DZP bit in the DCZID system register should be set if
the control bits which prohibit use of the DC ZVA instruction
have been set (it stands for Data Zero Prohibited). However
we had the sense of the test inverted; fix this so that the
bit reads correctly.

To avoid this regressing the behaviour of the user-mode
emulator, we must set the DZE bit in the SCTLR for that
config so that userspace continues to see DZP as zero (it
was getting the correct result by accident previously).

94cc44a9e5 disas/libvixl/a64/instructions-a64.h: Remove unused constants
The instructions-a64.h header defines a number of floating point
constants whose initializers are function calls. gcc 5 will warn
if these constants are not used by the C or C++ file which includes
the header, because they imply a runtime cost. Since for the files
QEMU uses from libvixl we don't use these constants at all, just
remove them.

Upstream intend to fix these by shifting to an 'extern const' in
the header plus definition in a suitable source file, so we can
drop this patch when we sync with the upcoming libvixl 1.7.

7797a73947 hmp: Remove "info pcmcia"
This command lists PCMCIA sockets and cards.  Only a few ARM boards
have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa,
verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev
"microdrive"), and it is only inserted during machine init, if ever.
So this command doesn't really tell anybody anything new so far.

Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged
by Coverity.  Has never been used, because there has never been code
to eject a PCMCIA card.

Not worth fixing & converting to QMP.  Remove it.

832390a5ed qemu-img: Print error if check failed
Currently, if bdrv_check() fails either by returning -errno or having
check_errors set, qemu-img check just exits with 1 after having told the
user that there were no errors on the image. This is bad.

Instead of printing the check result if there were internal errors which
were so bad that bdrv_check() could not even complete with 0 as a return
value, qemu-img check should inform the user about the error.

3cad83075c block: char devices on FreeBSD are not behind a pager
Introduce a new flag to mark devices that require requests to be aligned and
replace the usage of BDRV_O_NOCACHE and O_DIRECT with this flag when
appropriate.

If a character device is used as a backend on a FreeBSD host set this flag
unconditionally.

c6561586f0 get_maintainer.pl: restrict cases where it falls back to --git
The list emitted by --git-fallback often leads inexperienced contributors
to add pointless CCs.  While not discouraging usage of --git-fallback,
we want to:

1) disable the fallback if only some files lack a maintainer

    $ scripts/get_maintainer.pl -f util/cutils.c hw/ide/core.c
    Kevin Wolf <kwolf@redhat.com> (odd fixer:IDE)
    Stefan Hajnoczi <stefanha@redhat.com> (odd fixer:IDE)

This behavior is taken even if --git-fallback is specified.

2) warn the contributors about what we're doing, asking them to use their
common sense:

    $ scripts/get_maintainer.pl -f util/cutils.c
    get_maintainer.pl: No maintainers found, printing recent contributors.
    get_maintainer.pl: Do not blindly cc: them on patches!  Use common sense.

    Luiz Capitulino <lcapitulino@redhat.com> (commit_signer:1/2=50%)
    ...
    $

Explicitly disabling the fallback will not result in the warning message:

    $ scripts/get_maintainer.pl -f util/cutils.c   --no-git-fallback
    $ echo $?
    0

(Returning 1 would break usage of scripts/get_maintainer.pl as a cccmd
for git-send-email).
