  "message": "x86: UV: remove uv_flush_tlb_others() WARN_ON\n\nIn uv_flush_tlb_others() (arch/x86/kernel/tlb_uv.c),\nthe \"WARN_ON(!in_atomic())\" fails if CONFIG_PREEMPT is not enabled.\n\nAnd CONFIG_PREEMPT is not enabled by default in the distribution that\nmost UV owners will use.\n\nWe could #ifdef CONFIG_PREEMPT the warning, but that is not good form.\nAnd there seems to be no suitable fix to in_atomic() when CONFIG_PREMPT\nis not on.\n\nAs Ingo commented:\n\n  \u003e and we have no proper primitive to test for atomicity. (mainly\n  \u003e because we dont know about atomicity on a non-preempt kernel)\n\nSo we drop the WARN_ON.\n\nSigned-off-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
