Like Xu 33decbd2d3 hw: Replace global smp variables with MachineState for all remaining archs 
The global smp variables in alpha/hppa/mips/openrisc/sparc*/xtensa codes
are replaced with smp properties from MachineState.

A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.
