  "message": "[PATCH] x86: don\u0027t initialise cpu_possible_map to all ones\n\nInitialising cpu_possible_map to all-ones with CONFIG_HOTPLUG_CPU means that\n\na) All for_each_cpu() loops will iterate across all NR_CPUS CPUs, rather\n   than over possible ones.  That can be quite expensive.\n\nb) Soon we\u0027ll be allocating per-cpu areas only for possible CPUs.  So with\n   CPU_MASK_ALL, we\u0027ll be wasting memory.\n\nI also switched voyager over to not use CPU_MASK_ALL in the non-CPU-hotplug\ncase.  Should be OK..\n\nI note that parisc is also using CPU_MASK_ALL.  Suggest that it stop doing\nthat.\n\nCc: James Bottomley \u003cJames.Bottomley@steeleye.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Ashok Raj \u003cashok.raj@intel.com\u003e\nCc: Zwane Mwaikambo \u003czwane@linuxpower.ca\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
