Merge remote-tracking branch 'pmaydell/tags/pull-target-arm-20140108' into staging
target-arm queue:
* further A64 decoder patches, including enabling the aarch64-linux-user
target; this includes full floating point support. Neon is not yet
supported.
* cadence UART model fixes.
* some minor bug fixes and cleanups.
* all the softfloat fixes required by the new A64 instructions;
several of these will also be used by PPC.
