[PATCH 2/2] powerpc/64: Only warn for kuap locked when KCSAN not present

Arbitrary instrumented locations, including syscall handlers, can call arch_local_irq_restore() transitively when KCSAN is enabled, and in turn also replay_soft_interrupts_irqrestore(). The precondition on entry to this routine that is checked is that KUAP is enabled (user access prohibited).
