  "message": "time: remove obsolete CLOCK_TICK_ADJUST\n\nThe first version of the ntp_interval/tick_length inconsistent usage patch was\nrecently merged as bbe4d18ac2e058c56adb0cd71f49d9ed3216a405\n\nhttp://git.kernel.org/gitweb.cgi?p\u003dlinux/kernel/git/torvalds/linux-2.6.git;a\u003dcommit;h\u003dbbe4d18ac2e058c56adb0cd71f49d9ed3216a405\n\nWhile the fix did greatly improve the situation, it was correctly pointed out\nby Roman that it does have a small bug: If the users change clocksources after\nthe system has been running and NTP has made corrections, the correctoins made\nagainst the old clocksource will be applied against the new clocksource,\ncausing error.\n\nThe second attempt, which corrects the issue in the NTP_INTERVAL_LENGTH\ndefinition has also made it up-stream as commit\ne13a2e61dd5152f5499d2003470acf9c838eab84\n\nhttp://git.kernel.org/gitweb.cgi?p\u003dlinux/kernel/git/torvalds/linux-2.6.git;a\u003dcommit;h\u003de13a2e61dd5152f5499d2003470acf9c838eab84\n\nRoman has correctly pointed out that CLOCK_TICK_ADJUST is calculated\nbased on the PIT\u0027s frequency, and isn\u0027t really relevant to non-PIT\ndriven clocksources (that is, clocksources other then jiffies and pit).\n\nThis patch reverts both of those changes, and simply removes\nCLOCK_TICK_ADJUST.\n\nThis does remove the granularity error correction for users of PIT and Jiffies\nclocksource users, but the granularity error but for the majority of users, it\nshould be within the 500ppm range NTP can accommodate for.\n\nFor systems that have granularity errors greater then 500ppm, the\n\"ntp_tick_adj\u003d\" boot option can be used to compensate.\n\n[johnstul@us.ibm.com: provided changelog]\n[mattilinnanvuori@yahoo.com: maek ntp_tick_adj static]\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nAcked-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Matti Linnanvuori \u003cmattilinnanvuori@yahoo.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: mingo@elte.hu\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
