      "message": "Revert \"time: Remove xtime_cache\"\n\nThis reverts commit 7bc7d637452383d56ba4368d4336b0dde1bb476d, as\nrequested by John Stultz. Quoting John:\n\n \"Petr Titěra reported an issue where he saw odd atime regressions with\n  2.6.33 where there were a full second worth of nanoseconds in the\n  nanoseconds field.\n\n  He also reviewed the time code and narrowed down the problem: unhandled\n  overflow of the nanosecond field caused by rounding up the\n  sub-nanosecond accumulated time.\n\n  Details:\n\n   * At the end of update_wall_time(), we currently round up the\n  sub-nanosecond portion of accumulated time when storing it into xtime.\n  This was added to avoid time inconsistencies caused when the\n  sub-nanosecond portion was truncated when storing into xtime.\n  Unfortunately we don\u0027t handle the possible second overflow caused by\n  that rounding.\n\n   * Previously the xtime_cache code hid this overflow by normalizing the\n  xtime value when storing into the xtime_cache.\n\n   * We could try to handle the second overflow after the rounding up, but\n  since this affects the timekeeping\u0027s internal state, this would further\n  complicate the next accumulation cycle, causing small errors in ntp\n  steering. As much as I\u0027d like to get rid of it, the xtime_cache code is\n  known to work.\n\n   * The correct fix is really to include the sub-nanosecond portion in the\n  timekeeping accessor function, so we don\u0027t need to round up at during\n  accumulation. This would greatly simplify the accumulation code.\n  Unfortunately, we can\u0027t do this safely until the last three\n  non-GENERIC_TIME arches (sparc32, arm, cris) are converted  (those\n  patches are in -mm) and we kill off the spots where arches set xtime\n  directly. This is all 2.6.34 material, so I think reverting the\n  xtime_cache change is the best approach for now.\n\n  Many thanks to Petr for both reporting and finding the issue!\"\n\nReported-by: Petr Titěra \u003cP.Titera@century.cz\u003e\nRequested-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "avoid overflows in kernel/time.c\n\nWhen the conversion factor between jiffies and milli- or microseconds is\nnot a single multiply or divide, as for the case of HZ \u003d\u003d 300, we currently\ndo a multiply followed by a divide.  The intervening result, however, is\nsubject to overflows, especially since the fraction is not simplified (for\nHZ \u003d\u003d 300, we multiply by 300 and divide by 1000).\n\nThis is exposed to the user when passing a large timeout to poll(), for\nexample.\n\nThis patch replaces the multiply-divide with a reciprocal multiplication on\n32-bit platforms.  When the input is an unsigned long, there is no portable\nway to do this on 64-bit platforms there is no portable way to do this\nsince it requires a 128-bit intermediate result (which gcc does support on\n64-bit platforms but may generate libgcc calls, e.g.  on 64-bit s390), but\nsince the output is a 32-bit integer in the cases affected, just simplify\nthe multiply-divide (*3/10 instead of *300/1000).\n\nThe reciprocal multiply used can have off-by-one errors in the upper half\nof the valid output range.  This could be avoided at the expense of having\nto deal with a potential 65-bit intermediate result.  Since the intent is\nto avoid overflow problems and most of the other time conversions are only\nsemiexact, the off-by-one errors were considered an acceptable tradeoff.\n\nAt Ralf Baechle\u0027s suggestion, this version uses a Perl script to compute\nthe necessary constants.  We already have dependencies on Perl for kernel\ncompiles.  This does, however, require the Perl module Math::BigInt, which\nis included in the standard Perl distribution starting with version 5.8.0.\nIn order to support older versions of Perl, include a table of canned\nconstants in the script itself, and structure the script so that\nMath::BigInt isn\u0027t required if pulling values from said table.\n\nRunning the script requires that the HZ value is available from the\nMakefile.  Thus, this patch also adds the Kconfig variable CONFIG_HZ to the\narchitectures which didn\u0027t already have it (alpha, cris, frv, h8300, m32r,\nm68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or\nsh64 architectures, since Paul Mundt has dealt with those separately in the\nsh tree.\n\nSigned-off-by: H.
