1f29871cb7 Add MSR VSX and Associated Exception
This patch adds support for the VSX bit of the PowerPC Machine
State Register (MSR) as well as the corresponding VSX Unavailable
exception.

The VSX bit is added to the defined bits masks of the Power7 and
Power8 CPU models.

1e0c7e554e target-ppc: USE LPCR_ILE to control exception endian on POWER7
On POWER7, LPCR_ILE is used to control what endian guests take
their exceptions in so use it instead of MSR_ILE.

182735efaf cpu: Make first_cpu and next_cpu CPUState
Move next_cpu from CPU_COMMON to CPUState.
Move first_cpu variable to qom/cpu.h.

gdbstub needs to use CPUState::env_ptr for now.
cpu_copy() no longer needs to save and restore cpu_next.

97a8ea5a3a cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

259186a7d2 cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

68c2dd7006 PPC: Bring EPR support closer to reality
We already used to support the external proxy facility of FSL MPICs,
but only implemented it halfway correctly.

This patch adds support for

  * dynamic enablement of the EPR facility
  * interrupt acknowledgement only when the interrupt is delivered

This way the implementation now is closer to real hardware.

a1bb73849f ppc/booke: fix crit/mcheck/debug exceptions
Book E does not play games with certain bits of xSRR1 being MSR save
bits and others being error status.  xSRR1 is the old MSR, period.
This was causing things like MSR[CE] to be lost, even in the saved
version, as soon as you take an exception.

rfci/rfdi/rfmci are fixed to pass the actual xSRR1 register contents,
rather than the register number.

Put FIXME comments on the hack that is "asrr0/1".  The whole point of
separate exception levels is so that you can, for example, take a machine
check or debug interrupt without corrupting critical-level operations.
The right xSRR0/1 set needs to be chosen based on CPU type flags.

2f5a189cae ppc: Move load and store helpers, switch to AREG0 free mode
Add an explicit CPUPPCState parameter instead of relying on AREG0
and rename op_helper.c (which only contains load and store helpers)
to mem_helper.c. Remove AREG0 swapping in
tlb_fill().

Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation
and interrupt handling, cpu_{ld,st}{l,uw}_data in loads and stores.
