ARM: 7703/1: Disable preemption in broadcast_tlb*_a15_erratum() Commit 93dc688 (ARM: 7684/1: errata: Workaround for Cortex-A15 erratum 798181 (TLBI/DSB operations)) introduces calls to smp_processor_id() and smp_call_function_many() with preemption enabled. This patch disables preemption and also optimises the smp_processor_id() call in broadcast_tlb_mm_a15_erratum(). The broadcast_tlb_a15_erratum() function is changed to use smp_call_function() which disables preemption.
