  "message": "percpu: fix first chunk match in per_cpu_ptr_to_phys()\n\nper_cpu_ptr_to_phys() determines whether the passed in @addr belongs\nto the first_chunk or not by just matching the address against the\naddress range of the base unit (unit0, used by cpu0).  When an adress\nfrom another cpu was passed in, it will always determine that the\naddress doesn\u0027t belong to the first chunk even when it does.  This\nmakes the function return a bogus physical address which may lead to\ncrash.\n\nThis problem was discovered by Cliff Wickman while investigating a\ncrash during kdump on a SGI UV system.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nTested-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nCc: stable@kernel.org\n",
