      "message": "x86, nmi_watchdog: Remove ARCH_HAS_NMI_WATCHDOG and rely on CONFIG_HARDLOCKUP_DETECTOR\n\nThe x86 arch has shifted its use of the nmi_watchdog from a\nlocal implementation to the global one provide by\nkernel/watchdog.c.  This shift has caused a whole bunch of\ncompile problems under different config options.  I attempt to\nsimplify things with the patch below.\n\nIn order to simplify things, I had to come to terms with the\nmeaning of two terms ARCH_HAS_NMI_WATCHDOG and\nCONFIG_HARDLOCKUP_DETECTOR.  Basically they mean the same thing,\nthe former on a local level and the latter on a global level.\n\nWith the old x86 nmi watchdog gone, there is no need to rely on\ndefining the ARCH_HAS_NMI_WATCHDOG variable because it doesn\u0027t\nmake sense any more.  x86 will now use the global\nimplementation.\n\nThe changes below do a few things.  First it changes the few\nplaces that relied on ARCH_HAS_NMI_WATCHDOG to use\nCONFIG_X86_LOCAL_APIC (the former was an alias for the latter\nanyway, so nothing unusual here).  Those pieces of code were\nrelying more on local apic functionality the nmi watchdog\nfunctionality, so the change should make sense.\n\nSecond, I removed the x86 implementation of\ntouch_nmi_watchdog().  It isn\u0027t need now, instead x86 will rely\non kernel/watchdog.c\u0027s implementation.\n\nThird, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from\nx86.  And tweaked the include/linux/nmi.h file to tell users to\nlook for an externally defined touch_nmi_watchdog in the case of\nARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This\nchanges removes some of the ugliness in that file.\n\nFinally, I added a Kconfig dependency for\nCONFIG_HARDLOCKUP_DETECTOR that said you can\u0027t have\nARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR.  You can\nonly have one nmi_watchdog.\n\nTested with\nARCH\u003di386: allnoconfig, defconfig, allyesconfig, (various broken\nconfigs) ARCH\u003dx86_64: allnoconfig, defconfig, allyesconfig,\n(various broken configs)\n\nHopefully, after this patch I won\u0027t get any more compile broken\nemails. :-)\n\nv3:\n  changed a couple of \u0027linux/nmi.h\u0027 -\u003e \u0027asm/nmi.h\u0027 to pick-up correct function\n  prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: fweisbec@gmail.com\nLKML-Reference: \u003c1293044403-14117-1-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

On many Dell\nmachines, these windows overlap some E820 reserved areas, e.g.,\n\n    BIOS-e820: 00000000bfe4dc00 - 00000000c0000000 (reserved)\n    pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xdfffffff]\n\nIf we put devices at 0xbff00000, they don\u0027t work, probably because\nthat\u0027s really RAM, not I/O memory.  This patch prevents that by removing\nthe 0xbfe4dc00-0xbfffffff area from the \"available\" resource.\n\nI\u0027m not very happy with this solution because Windows solves the problem\ndifferently (it seems to ignore E820 reserved areas and it allocates\ntop-down instead of bottom-up; details at comment 45 of the bugzilla\nbelow).  That means we\u0027re vulnerable to BIOS defects that Windows would not\ntrip over.  For example, if BIOS described a device in ACPI but didn\u0027t\nmention it in E820, Windows would work fine but Linux would fail.\n\nReference: https://bugzilla.kernel.org/show_bug.cgi?id\u003d16228\nAcked-by: H.

      "message": "x86: Improve TSC calibration using a delayed workqueue\n\nBoot to boot the TSC calibration may vary by quite a large amount.\n\nWhile normal variance of 50-100ppm can easily be seen, the quick\ncalibration code only requires 500ppm accuracy, which is the limit\nof what NTP can correct for.\n\nThis can cause problems for systems being used as NTP servers, as\nevery time they reboot it can take hours for them to calculate the\nnew drift error caused by the calibration.\n\nThe classic trade-off here is calibration accuracy vs slow boot times,\nas during the calibration nothing else can run.\n\nThis patch uses a delayed workqueue  to calibrate the TSC over the\nperiod of a second. This allows very accurate calibration (in my\ntests only varying by 1khz or 0.4ppm boot to boot). Additionally this\nrefined calibration step does not block the boot process, and only\ndelays the TSC clocksoure registration by a few seconds in early boot.\nIf the refined calibration strays 1% from the early boot calibration\nvalue, the system will fall back to already calculated early boot\ncalibration.\n\nCredit to Andi Kleen who suggested using a timer quite awhile back,\nbut I dismissed it thinking the timer calibration would be done after\nthe clocksource was registered (which would break things). Forgive\nme for my short-sightedness.\n\nThis patch has worked very well in my testing, but TSC hardware is\nquite varied so it would probably be good to get some extended\ntesting, possibly pushing inclusion out to 2.6.39.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nLKML-Reference: \u003c1289003985-29060-1-git-send-email-johnstul@us.ibm.com\u003e\nReviewed-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Ingo Molnar \u003cmingo@elte.hu\u003e\nCC: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCC: Clark Williams \u003cwilliams@redhat.com\u003e\nCC: Andi Kleen \u003candi@firstfloor.org\u003e\n"

The perf nmi handler uses the fact that crossing\na zero means the counter overflowed (for those counters that do not have\nspecific interrupt bits). Therefore on kvm guests, perf will swallow all\nNMIs thinking the counters overflowed.\n\nThis causes problems for subsystems like kgdb which needs NMIs to do its\nmagic. This problem was discovered by running kgdb tests.\n\nThe solution is to write garbage into a perf counter during the\ninitialization and hopefully reading back the same number.  On kvm\nguests, the value will be read back as zero and we disable perf as\na result.\n\nReported-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nPatch-inspired-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nLKML-Reference: \u003c1290462923-30734-1-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "x86: Eliminate bp argument from the stack tracing routines\n\nThe various stack tracing routines take a \u0027bp\u0027 argument in which the\ncaller is supposed to provide the base pointer to use, or 0 if doesn\u0027t\nhave one. Since bp is garbage whenever CONFIG_FRAME_POINTER is not\ndefined, this means all callers in principle should either always pass\n0, or be conditional on CONFIG_FRAME_POINTER.\n\nHowever, there are only really three use cases for stack tracing:\n\n(a) Trace the current task, including IRQ stack if any\n(b) Trace the current task, but skip IRQ stack\n(c) Trace some other task\n\nIn all cases, if CONFIG_FRAME_POINTER is not defined, bp should just\nbe 0.  If it _is_ defined, then\n\n- in case (a) bp should be gotten directly from the CPU\u0027s register, so\n  the caller should pass NULL for regs,\n\n- in case (b) the caller should should pass the IRQ registers to\n  dump_trace(),\n\n- in case (c) bp should be gotten from the top of the task\u0027s stack, so\n  the caller should pass NULL for regs.\n\nHence, the bp argument is not necessary because the combination of\ntask and regs is sufficient to determine an appropriate value for bp.\n\nThis patch introduces a new inline function stack_frame(task, regs)\nthat computes the desired bp. This function is then called from the\ntwo versions of dump_stack().\n\nSigned-off-by: Soren Sandmann \u003cssp@redhat.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: H.
