[SPARC64]: Disable preemption during flush_tlb_pending(). A context switch will force a call to flush_tlb_pending() (via switch_to()), so if we test tlb_nr to be non-zero, then sleep, it would become zero and later back at the original context we'll pass zero down into the TLB flushing code which should never see a nr argument of zero.
