  "message": "percpu: fix DEBUG_PREEMPT per_cpu checking\n\n2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT\u0027s per_cpu checking\non several architectures.  On s390, sparc64 and x86 it\u0027s been weakened to\nnot checking at all; whereas on powerpc64 it\u0027s become too strict, issuing\nwarnings from __raw_get_cpu_var in io_schedule and init_timer for example.\n\nFix this by weakening powerpc\u0027s __my_cpu_offset to use the non-checking\nlocal_paca instead of get_paca (which itself contains such a check);\nand strengthening the generic my_cpu_offset to go the old slow way via\nsmp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is\nwhere all the knowledge of what\u0027s correct when lives).\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nReviewed-by: Mike Travis \u003ctravis@sgi.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
