  "message": "[POWERPC] ppc64: support CONFIG_DEBUG_PREEMPT\n\nAdd CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing\nget_paca() preemption.  Cheat a little, just use debug_smp_processor_id()\nin the debug version of get_paca(): it contains all the right checks and\nreporting, though get_paca() doesn\u0027t really use smp_processor_id().\n\nUse local_paca for what might have been called __raw_get_paca().\nSilence harmless warnings from io.h and lparcfg.c with local_paca -\nit is okay for iseries_lparcfg_data to be referencing shared_proc\nwith preemption enabled: all cpus should show the same value for\nshared_proc.\n\nWhy do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT?\nI don\u0027t know, ppc64 appears to get along fine without it.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
