  "message": "nohz: Allow 32-bit machines to sleep for more than 2.15 seconds\n\nIn the dynamic tick code, \"max_delta_ns\" (member of the\n\"clock_event_device\" structure) represents the maximum sleep time\nthat can occur between timer events in nanoseconds.\n\nThe variable, \"max_delta_ns\", is defined as an unsigned long\nwhich is a 32-bit integer for 32-bit machines and a 64-bit\ninteger for 64-bit machines (if -m64 option is used for gcc).\nThe value of max_delta_ns is set by calling the function\n\"clockevent_delta2ns()\" which returns a maximum value of LONG_MAX.\nFor a 32-bit machine LONG_MAX is equal to 0x7fffffff and in\nnanoseconds this equates to ~2.15 seconds. Hence, the maximum\nsleep time for a 32-bit machine is ~2.15 seconds, where as for\na 64-bit machine it will be many years.\n\nThis patch changes the type of max_delta_ns to be \"u64\" instead of\n\"unsigned long\" so that this variable is a 64-bit type for both 32-bit\nand 64-bit machines. It also changes the maximum value returned by\nclockevent_delta2ns() to KTIME_MAX.  Hence this allows a 32-bit\nmachine to sleep for longer than ~2.15 seconds. Please note that this\npatch also changes \"min_delta_ns\" to be \"u64\" too and although this is\nunnecessary, it makes the patch simpler as it avoids to fixup all\ncallers of clockevent_delta2ns().\n\n[ tglx: changed \"unsigned long long\" to u64 as we use this data type\n  \tthrough out the time code ]\n\nSigned-off-by: Jon Hunter \u003cjon-hunter@ti.com\u003e\nCc: John Stultz \u003cjohnstul@us.ibm.com\u003e\nLKML-Reference: \u003c1250617512-23567-3-git-send-email-jon-hunter@ti.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
