virtio-serial-bus: use bh for unthrottling
Instead of calling flush_queued_data when unthrottling, schedulea bh. That way we can return immediately to the caller, and theflush uses the same call path as a have_data for callbackee.
No migration change is required because bh are called from vm_stop....
virtio-serial: Plug memory leak on qdev exit()
virtio_serial_init() allocates the VirtIOSerialBus dynamically, butvirtio_serial_exit() doesn't free it.
Fix by getting rid of the allocation.

target-arm: Signal Underflow when denormal flushed to zero on output
On ARM the architecture mandates that when an output denormal is flushed tozero we must set the FPSCR UFC (underflow) bit, so map softfloat'sfloat_flag_output_denormal accordingly.

target-arm: Use correct float status for Neon int-float conversions
The Neon versions of int-float conversions must use the "standard FPSCR" rather than the default FPSCR. Implement this by having the helperfunctions take a pointer to the appropriate float_status value rather...
target-arm: Signal InvalidOp for Neon GE and GT compares of QNaN
If the input to a Neon float comparison is a quiet NaN, the ARM ARMspecifies that we should raise InvalidOp if the comparison is GE or GTbut not for EQ. (Signaling NaNs raise InvalidOp regardless). This means...
target-arm: Signal InputDenormal for VRECPE, VRSQRTE, VRECPS, VRSQRTS
The helpers for VRECPE.F32, VSQRTE.F32, VRECPS and VRSQRTS handle denormalsas special cases, so we must set the InputDenormal exception flag ourselves.
softfloat: Add new flag for when denormal result is flushed to zero
Add a new float_flag_output_denormal which is set when the resultof a floating point operation would be denormal but is flushed tozero because we are in flush_to_zero mode. This is necessary because...
