  s390x: fix -initrd in virtio machine

When using -initrd in the virtio machine, we need to indicate the initrd
start and size inside the kernel image. These parameters need to be stored
in native endianness.

  s390/kvm_stat: correct sys_perf_event_open syscall number

Correct sys_perf_event_open syscall number for s390 architecture
   - the hardcoded syscall number 298 is for x86 but should
     be different for other architectures.
     In case we figure out via /proc/cpuinfo that we are running
     on s390 the appropriate syscall number is used from map
     syscall_numbers; other architectures can extend this.

  s390: use sync regs for register transfer

Newer kernels provide the guest registers in kvm_run. Lets use
those if available (i.e. the capability is set). This avoids
ioctls on cpu_synchronize_state making intercepts faster.

In addition, we have now the prefix register, the access registers
the control registers up to date. This helps in certain cases,
e.g. for resolving kernel module addresses with gdb on a guest.

On return, we update the registers according to the level statement,
i.e. we put all registers for KVM_PUT_FULL_STATE and _RESET_STATE.

  s390: sclp base support

This adds a more generic infrastructure for handling Service-Call
requests on s390. Currently we only support a small subset of Read
SCP Info directly in target-s390x. This patch provides the base
infrastructure for supporting more commands and moves Read SCP
Info.
In the future we could add additional commands for hotplug, call
home and event handling.

  s390: sclp event support

Several SCLP features are considered to be events. Those events don't
provide SCLP commands on their own, instead they are all based on
Read Event Data, Write Event Data, Write Event Mask and the service
interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via
system_powerdown) and the ASCII console.
Further down the road the sclp line mode console and configuration
change events (e.g. cpu hotplug) can be implemented.

  s390: sclp signal quiesce support

This implements the sclp signal quiesce event via the SCLP Event
Facility.
This allows to gracefully shutdown a guest by using system_powerdown
notifiers. It creates a service interrupt that will trigger a
Read Event Data command from the guest. This code will then add an
event that is interpreted by linux guests as ctrl-alt-del.

  s390: sclp ascii console support

This code adds console support  by implementing SCLP's ASCII Console
Data event. This is the same console as LPARs ASCII console or z/VMs
sysascii.

The console can be specified manually with something like
-chardev stdio,id=charconsole0 -device 
sclpconsole,chardev=charconsole0,id=console0

Newer kernels will autodetect that console and prefer that over virtio
console.

When data is received from the character layer it creates a service
interrupt to trigger a Read Event Data command from the guest that will
pick up the received character byte-stream.
When characters are echo'ed by the linux guest a Write Event Data occurs
which is forwarded by the Event Facility to the console that supports
a corresponding mask value.
Console resizing is not supported.
The character layer byte-stream is buffered using a fixed size iov
buffer.

  tcg/mips: use MUL instead of MULT on MIPS32 and above

MIPS32 and later instruction sets have a multiplication instruction
directly operating on GPRs. It only produces a 32-bit result but
it is exactly what is needed by QEMU.
