This reverts commit 1a443c1b8b and the
later commit 395071a763.

GSequence was introduced in glib 2.14.  RHEL 5 fails to compile since it
uses glib 2.12.3.

Now that bdrv_iterate_format() invokes the iteration callback in sorted
order these commits are unnecessary.

Alex Williamson 9db2efd95e x86: Clear MTRRs on vCPU reset
The SDM specifies (June 2014 Vol3 11.11.5):

    On a hardware reset, the P6 and more recent processors clear the
    valid flags in variable-range MTRRs and clear the E flag in the
    IA32_MTRR_DEF_TYPE MSR to disable all MTRRs. All other bits in the
    MTRRs are undefined.

We currently do none of that, so whatever MTRR settings you had prior
to reset is what you have after reset.  Usually this doesn't matter
because KVM often ignores the guest mappings and uses write-back
anyway.  However, if you have an assigned device and an IOMMU that
allows NoSnoop for that device, KVM defers to the guest memory
mappings which are now stale after reset.  The result is that OVMF
rebooting on such a configuration takes a full minute to LZMA
decompress the firmware volume, a process that is nearly instant on
the initial boot.

Alex Williamson d1ae67f626 x86: kvm: Add MTRR support for kvm_get|put_msrs()
The MTRR state in KVM currently runs completely independent of the
QEMU state in CPUX86State.mtrr_*.  This means that on migration, the
target loses MTRR state from the source.  Generally that's ok though
because KVM ignores it and maps everything as write-back anyway.  The
exception to this rule is when we have an assigned device and an IOMMU
that doesn't promote NoSnoop transactions from that device to be cache
coherent.  In that case KVM trusts the guest mapping of memory as
configured in the MTRR.

This patch updates kvm_get|put_msrs() so that we retrieve the actual
vCPU MTRR settings and therefore keep CPUX86State synchronized for
migration.  kvm_put_msrs() is also used on vCPU reset and therefore
allows future modificaitons of MTRR state at reset to be realized.

Note that the entries array used by both functions was already
slightly undersized for holding every possible MSR, so this patch
increases it beyond the 28 new entries necessary for MTRR state.

Alexey Kardashevskiy 3dd7852f19 s390x: Migrate to new NMI interface
This implements an NMI interface for s390 and s390-ccw machines.

This removes #ifdef s390 branch in qmp_inject_nmi so new s390's
nmi_monitor_handler() callback is going to be used for NMI.

Since nmi_monitor_handler()-calling code is platform independent,
CPUState::cpu_index is used instead of S390CPU::env.cpu_num.
There should not be any change in behaviour as both @cpu_index and
@cpu_num are global CPU numbers.

Note that s390_cpu_restart() already takes care of the specified cpu,
so we don't need to schedule via async_run_on_cpu().

Since the only error s390_cpu_restart() can return is ENOSYS, convert
it to QERR_UNSUPPORTED.

Alexey Kardashevskiy d07aa7c7bb s390x: Convert QEMUMachine to MachineClass
This converts s390-virtio and s390-ccw-virtio machines to QOM MachineClass.
This brings ability to add interfaces to the machine classes. The first
interface for addition will be NMI.

The patch is mechanical so no change in behavior is expected.

Alexey Kardashevskiy 9cb805fd26 cpus: Define callback for QEMU "nmi" command
This introduces an NMI (Non Maskable Interrupt) interface with
a single nmi_monitor_handler() method. A machine or a device can
implement it. This searches for an QOM object with this interface
and if it is implemented, calls it. The callback implements an action
required to cause debug crash dump on in-kernel debugger invocation.
The callback returns Error**.

This adds a nmi_monitor_handle() helper which walks through
all objects to find the interface. The interface method is called
for all found instances.

This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.

This changes inject-nmi command description for HMP and QMP.

    acpi-build: tweak acpi migration limits
broke kernel loading with -kernel/-initrd: it doubled
the size of ACPI tables but did not reserve
enough memory.

As a result, issues on boot and halt are observed.

Fix this up by doubling reserved memory for new machine types.

Stefan Weil bcc55f327c po: Fix Makefile rules for in-tree builds without configuration
Adding 'update' to the phony targets fixes this error:

$ LANG=C make -C po update
make: Entering directory `/qemu/po'
  LINK  update
/qemu/po/de_DE.po: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
make: *** [update] Error 1
make: Leaving directory `/qemu/po'

Some other phony targets (build, install) were also added, and the
existing .PHONY statement was moved to a more prominent position at
the beginning of the Makefile.

The patch also fixes a 2nd bug. The default target should be 'all',
but instead 'modules' (from rules.mak) was the default. Fix this by
adding 'all' as a target before any include statement.
