nothing in the codebase defines that, and so in fact these functions
are always present. Drop the unnecessary #ifdefs.

(Over a decade ago thunk.h used to be included by some softmmu

gdbstub: set listen backlog to 1

Avoid possible connection drops on Linux (when tcp_syncookies is

    TCP: request_sock_TCP: Possible SYN flooding on port 1234. Sending cookies.  Check SNMP counters.

Since Linux 4.4 (ef547f2ac16b "tcp: remove max_qlen_log"), a backlog of
zero is really treated as the "queue length for completely established

interpretation of an "implementation-defined minimum value" for a

docker: Don't use eval trick on Makefile

The eval trick for defining DOCKER_SRC_COPY doesn't do anything
useful, as DOCKER_SRC_COPY is immediately expanded just after it
is defined, and CUR_TIME is already defined using ":=". Simply
define it using ":=" so it is evaluated only once.

The eval trick was also triggering an weird error on Travis builds:
  qemu/tests/docker/Makefile.include:34: *** unterminated variable reference.  Stop.

The issue is not easily reproducible (maybe it's a bug in some
versions of Make), but it is avoided if removing the eval trick.

virtio-blk: Remove op blocker for dataplane

Block layer is prepared to unspecialize dataplane, an evidence is this

two (actually three if DATAPLANE itself counts but blockdev.c makes sure
attaching twice is not possible): MIRROR_TARGET and BACKUP_TARGET.

blockdev-mirror refuses to start if target is attached, so the first is
not a problem.

By removing BACKUP_TARGET, blockdev-backup will become permissive to

non-dataplane given the latter is already possible. In either case,

virtio: move bi-endian target support to a single location

Paolo's recent cpu.h cleanups broke legacy virtio for ppc64 LE guests (and
arm BE guests as well, even if I have not verified that). Especially, commit
"33c11879fd42 qemu-common: push cpu.h inclusion out of qemu-common.h" has
the side-effect of silently hiding the TARGET_IS_BIENDIAN macro from the
virtio memory accessors, and thus fully disabling support of endian changing
targets.

To be sure this cannot happen again, let's gather all the bi-endian bits
where they belong in include/hw/virtio/virtio-access.h.

The changes in hw/virtio/vhost.c are safe because vhost_needs_vring_endian()
is not called on a hot path and non bi-endian targets will return false
anyway.

While here, also rename TARGET_IS_BIENDIAN to be more precise: it is only for
legacy virtio and bi-endian guests.

ppc patch queue for 2016-05-31

Latest patch queue for ppc.  Several significant things in here:
  * A bunch of patches from BenH fixing things in TCG
     - This should fix several regressions introduced by recent
       patches for better HV mode support
     - It also fixes some other bugs discovered along the way
  * Some fixes and cleanups for Mac machine types from Marc
    Cave-Ayland
  * Preliminary patches towards dynamic DMA window support from Alexey
    Kardashevskiy
      - This includes a patch to migration code code
  * Increase number of hotpluggable memory slots
      - Includes a change to KVM generic code, ACKed by Paolo
  * Another TCG fix for an SPE instruction

ppc: Do not take exceptions on unknown SPRs in privileged mode

The architecture specifies that mtspr/mfspr on an unknown SPR number
should act as a nop in privileged mode.

I haven't removed the warning however as it can be useful for
diagnosing.

ppc: Add missing slbfee. instruction on ppc64 BookS processors

Used to lookup SLB entries by address, for some reason it was missing.

ppc: Fix slbia decode

Since at least the 2.05 architecture, the slbia instruction takes an
IH field in the opcode to provide some control on the effect of the
slbia on the ERATs (level-1 TLB).

We can safely ignore it as we always flush the whole qemu TLB but
we should allow the bits in the decode.

ppc: Fix mtmsr decoding

We had code to handle the L bit in the opcode but we didn't
allow it in the decode mask.

ppc: POWER7 has lq/stq instructions and stq need to check ISA

The PPC_64BX instruction flag is used for a couple of newer
instructions currently on POWER8 but our implementation for
them works for POWER7 too (and already does the proper checking
of what is permitted) with one exception: stq needs to check
the ISA version.

This fixes the latter and add the instructions to POWER7
