      [PATCH] init call cleanup · 0bb3184d
      Li Shaohua 提交于
      Trival patch for CPU hotplug.  In CPU identify part, only did cleaup for intel
      CPUs.  Need do for other CPUs if they support S3 SMP.

      [PATCH] i386 CPU hotplug · f3705136
      Zwane Mwaikambo 提交于
      (The i386 CPU hotplug patch provides infrastructure for some work which Pavel
      is doing as well as for ACPI S3 (suspend-to-RAM) work which Li Shaohua
      <shaohua.li@intel.com> is doing)
      
      The following provides i386 architecture support for safely unregistering and
      registering processors during runtime, updated for the current -mm tree.  In
      order to avoid dumping cpu hotplug code into kernel/irq/* i dropped the
      cpu_online check in do_IRQ() by modifying fixup_irqs().  The difference being
      that on cpu offline, fixup_irqs() is called before we clear the cpu from
      cpu_online_map and a long delay in order to ensure that we never have any
      queued external interrupts on the APICs.  There are additional changes to s390
      and ppc64 to account for this change.
      
      1) Add CONFIG_HOTPLUG_CPU
      2) disable local APIC timer on dead cpus.
      3) Disable preempt around irq balancing to prevent CPUs going down.
      4) Print irq stats for all possible cpus.
      5) Debugging check for interrupts on offline cpus.
      6) Hacky fixup_irqs() to redirect irqs when cpus go off/online.
      7) play_dead() for offline cpus to spin inside.
      8) Handle offline cpus set in flush_tlb_others().
      9) Grab lock earlier in smp_call_function() to prevent CPUs going down.
      10) Implement __cpu_disable() and __cpu_die().
      11) Enable local interrupts in cpu_enable() after fixup_irqs()
      12) Don't fiddle with NMI on dead cpu, but leave intact on other cpus.
      13) Program IRQ affinity whilst cpu is still in cpu_online_map on offline.

      [PATCH] check nmi watchdog is broken · 67701ae9
      Jack F Vogel 提交于
      A bug against an xSeries system showed up recently noting that the
      check_nmi_watchdog() test was failing.
      
      I have been investigating it and discovered in both i386 and x86_64 the
      recent change to the routine to use the cpu_callin_map has uncovered a
      problem.  Prior to that change, on an SMP box, the test was trivally
      passing because all cpu's were found to not yet be online, but now with the
      callin_map they are discovered, it goes on to test the counter and they
      have not yet begun to increment, so it announces a CPU is stuck and bails
      out.
      
      On all the systems I have access to test, the announcement of failure is
      also bougs...  by the time you can login and check /proc/interrupts, the
      NMI count is happily incrementing on all CPUs.  Its just that the test is
      being done too early.
      
      I have tried moving the call to the test around a bit, and it was always
      too early.  I finally hit on this proposed solution, it delays the routine
      via a late_initcall(), seems like the right solution to me.

      [PATCH] pm_message_t: more fixes in common and i386 · 438510f6
      Pavel Machek 提交于
      I thought I'm done with fixing u32 vs.  pm_message_t ...  unfortunately
      that turned out not to be the case as Russel King pointed out.  Here are
      fixes for Documentation and common code (mainly system devices).

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
