6c93329186 .travis.yml: collapse the test matrix
Remove the concept of TARGETS and build the complete target list for
each config combination. Now the matrix is just based on CONFIG stanzas
and we use the additional stuff for:

  - things that only work on one compiler (sparse, gcov, gprof)
  - combos where "make check" fails

1dbc7cc9b9 ppc patch queue for 2016-03-24
Three bugfixes for target-ppc, pseries machine type and related devices.
 
 1. Fix a bug in the core code where kvm_vcpu_dirty would not be set
    before the very first system reset.  This meant that if things in
    the reset path did their own cpu_synchronize_state() it would pull
    stale data out of KVM.
 
    On ppc this, in combination with a previous cleanup meant that the
    MSR would be zeroed before entry, instead of correctly having the
    SF (64-bit mode) bit set.
 
 2. Allow immediate detach of hot-added PCI devices which haven't yet
    been announced to the guest.
 
    This fixes a regression: because of a case where we now defer
    announcement of non-zero functions to the guest, an incorrect
    hot-add of such a device can't be backed out until the add is
    completed, which is counter-intuitive to say the least.
 
 3. Fix migration of alternate interrupt locations.  The location of
    interrupt vectors can be affected by the LPCR, and we weren't
    correctly recalculating this after migration of a non-standard LPCR
    value.

76b223200e block: Forbid I/O throttling on nodes with multiple parents for 2.6
As the patches to move I/O throttling to BlockBackend didn't make it in
time for the 2.6 release, but the release adds new ways of configuring
VMs whose behaviour would change once the move is done, we need to
outlaw such configurations temporarily.

The problem exists whenever a BDS has more users than just its BB, for
example it is used as a backing file for another node. (This wasn't
possible in 2.5 yet as we introduced node references to specify a
backing file only recently.) In these cases, the throttling would
apply to these other users now, but after moving throttling to the
BlockBackend the other users wouldn't be throttled any more.

This patch prevents making new references to a throttled node as well as
using monitor commands to throttle a node with multiple parents.

Compared to 2.5 this changes behaviour in some corner cases where
references were allowed before, like bs->file or Quorum children. It
seems reasonable to assume that users didn't use I/O throttling on such
low level nodes. With the upcoming move of throttling into BlockBackend,
such configurations won't be possible anyway.

Failing on -drive/drive_add created BlockBackends was a

And without a DriveInfo:

efdaf797de vl: Move cpu_synchronize_all_states() into qemu_system_reset()
There are currently 3 calls to qemu_system_reset() in vl.c.  Two of them
are immediately preceded by a cpu_synchronize_all_states9) and the
remaining one should be.

The one which doesn't is the very first reset called directly from main().
Without a cpu_synchronize_all_states(), kvm_vcpu_dirty is false at this
point from the earlier cpu_synchronize_all_post_init().  That's incorrect
because the reset path is quite likely to update the CPU state, and that
updated state should be pushed back to KVM, not overwritten with stale
data pushed to KVM immediately after init.

This patch moves the call to cpu_synchronize_all_states() into
qemu_system_reset() for safety, so it is always called.  AFAICT this should
be safe for the handful of callers outside vl.c - these all appear to be in
places where the cpu state is already synchronized so the extra call
will be a no-op.

f40eb921da spapr_drc: enable immediate detach for unsignalled devices
Currently spapr doesn't support "aborting" hotplug of PCI
devices by allowing device_del to immediately remove the
device if we haven't signalled the presence of the device
to the guest.

In the past this wasn't an issue, since we always immediately
signalled device attach and simply relied on full guest-aware
add->remove path for device removal. However, as of 788d259,
we now defer signalling for PCI functions until function 0
is attached, so now we need to deal with these "abort" operations
for cases where a user hotplugs a non-0 function, then opts to
remove it prior hotplugging function 0. Currently they'd have to
reboot before the unplug completed. PCIe multifunction hotplug
does not have this requirement however, so from a management
implementation perspective it would be good to address this within
the same release as 788d259.

We accomplish this by simply adding a 'signalled' flag to track
whether a device hotplug event has been sent to the guest. If it
hasn't, we allow immediate removal under the assumption that the
guest will not be using the device. Devices present at boot/reset
time are also assumed to be 'signalled'.

For CPU/memory/etc, signalling will still happen immediately
as part of device_add, so only PCI functions should be affected.

bf06c1123a target-arm: Make the 64-bit version of VTCR do the migration
Move the ALIAS tag from VTCR_EL2 to VTCR so that we migrate the
64-bit version, as is usual. (This has no particular effect now
unless the guest wrote to the high RES0 bits of VTCR_EL2.)
Add a comment about why it's OK that we don't have the various
accessor functions that the EL1 TCR regdefs do.

e24fdd238a target-arm: Correctly reset SCTLR_EL3 for 64-bit CPUs
The regdef for SCTRL_EL3 was incorrectly marked as being an
ARM_CP_ALIAS, with the remark that this was because the 32-bit
definition would take care of reset and migration. However the
intention for banked registers as documented in the comment in
add_cpreg_to_hashtable() is:

 * 2) If ARMv8 is enabled then we can count on a 64-bit version
 *    taking care of the secure bank.  This requires that separate
 *    32 and 64-bit definitions are provided.

and so it marks the 32-bit secure banked version as an alias.
This results in the sctlr_s/sctlr_el[3] field never being reset
or migrated for a 64-bit CPU with EL3 enabled.

Fix this by removing the ARM_CP_ALIAS annotation from SCTLR_EL3.
Since this means it now needs a real reset value, move the regdef
into the same place that we define the 32-bit SCTLR.

The new-in-ARMv8 YIELD instruction has been implemented to throw
an EXCP_YIELD back up to the QEMU main loop. In system emulation
we use this to decide to schedule a different guest CPU in SMP
configurations. In usermode emulation there is nothing to do,
so just ignore it and resume the guest.

This prevents an abort with "unhandled CPU exception 0x10004"
if the guest process uses the YIELD instruction.

  slirp: Fix migration from older versions of QEMU to the current one

eaf136f9a2 slirp: Fix migration from older versions of QEMU to the current one
While adding the IPv6 support, the commit eae303ff23
("slirp: Make Socket structure IPv6 compatible") changed the format of
the migration stream, without taking into account that we might still
receive an old migration stream layout when upgrading from QEMU version
2.5 (or older) to QEMU 2.6. Currently, QEMU bails out when doing a
migration from QEMU 2.5 to the recent master version when it has
been started with a "-net user,guestfwd=..." network. So let's fix
this by checking the version ID of the migration stream and by using
the old behavior if we've detected version 3 or less.

ae50a7702c arm: qmp: add query-gic-capabilities interface
This patch add "query-gic-capabilities" but does not implement it. The
command is ARM-only. The command will return a list of GICCapability
structs that describes all GIC versions that current QEMU and system
support.

Libvirt is possibly the first consumer of this new command.

Before this patch, a libvirt user can successfully configure all kinds
of GIC devices for ARM guests, no matter whether current QEMU/kernel
supports them. If the specified GIC version/type is not supported, the
user will get an ambiguous "QEMU boot failure" error when trying to start
the VM. This is not user-friendly.

With this patch, libvirt should be able to query which type (and which
version) of GIC device is supported. Using this information, libvirt
can warn the user during configuration of guests when specified GIC
device type is not supported. Or better, we can just list those versions
that we support, and filter out the unsupported ones.

For example, if we got the query result:

{"return": [{"emulated": false, "version": 3, "kernel": true},
            {"emulated": true, "version": 2, "kernel": false}]}

then it means that we support emulated GIC version 2 using:

  qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ...

or KVM-accelerated GIC version 3 using:

  qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ...

If we specify other explicit GIC versions rather than the above, QEMU
will not be able to boot.

The community is working on a more generic way to query these kinds of
information about valid values of machine properties. However, due to
the importance of supporting this specific use case, weecided to first
implement this ad-hoc one; then when the generic method is ready, we
can move on to that one smoothly.
