data_access_slb_common+0x138/0x180 # # This is caused by the get_paca() in slb_allocate_kernel(), which # includes a call to debug_smp_processor_id(). # # slb_allocate_kernel() can only be called from do_slb_fault(), and in # that path interrupts are hard disabled and so we can't be preempted, # but we can't update the preempt flags (in thread_info) because that # could cause an SLB fault. # # So just use local_paca which is safe and doesn't cause the warning. # # Fixes: 48e7b7695745 ("powerpc/64s/hash: Convert SLB miss handlers to C") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # <
