[IA64] pvops: preparation: introduce ia64_get_psr_i() to make kernel paravirtualization friendly.
__local_irq_save() and local_save_flags() are used to mask interruptions.
They read all psr bits that requres whole bit emulation.
On the other hand, reading only psr.i, the single bit, can be virtualized
cheaply.
