Michael Ellerman 684c68d92e Revert "powerpc/irq: Don't open code irq_soft_mask helpers" 
This reverts commit ef5b570d37.

Zhouyi reported that commit is causing crashes when running rcutorture
with KASAN enabled:

  BUG: using smp_processor_id() in preemptible [00000000] code: rcu_torture_rea/100
  caller is rcu_preempt_deferred_qs_irqrestore+0x74/0xed0

KASAN will generate instrumentation instructions around the
WRITE_ONCE(local_paca->irq_soft_mask, mask):

   0xc000000000295cf4 <+68>:	mtlr    r0

If there is a context switch before "stb     r9,2354(r31)", r31 may
not equal to r13, in such case, irq soft mask will not work.

The usual solution of marking the code ineligible for instrumentation
forces the code out-of-line, which we would prefer to avoid. Christophe
proposed a partial revert, but Nick raised some concerns with that. So
for now do a full revert.
