      x86/apic/timer: Set ->min_delta_ticks and ->max_delta_ticks · 747d04b3
      Nicolai Stange 提交于
      In preparation for making the clockevents core NTP correction aware,
      all clockevent device drivers must set ->min_delta_ticks and
      ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
      clockevent device's rate is going to change dynamically and thus, the
      ratio of ns to ticks ceases to stay invariant.
      
      Make the x86 arch's apic clockevent driver initialize these fields
      properly.
      
      This patch alone doesn't introduce any change in functionality as the
      clockevents core still looks exclusively at the (untouched) ->min_delta_ns
      and ->max_delta_ns. As soon as this has changed, a followup patch will
      purge the initialization of ->min_delta_ns and ->max_delta_ns from this
      driver.

      x86/acpi: Restore the order of CPU IDs · 2b85b3d2
      Dou Liyang 提交于
      The following commits:
      
        f7c28833 ("x86/acpi: Enable acpi to register all possible cpus at
      boot time") and 8f54969d ("x86/acpi: Introduce persistent storage
      for cpuid <-> apicid mapping")
      
      ... registered all the possible CPUs at boot time via ACPI tables to
      make the mapping of cpuid <-> apicid fixed. Both enabled and disabled
      CPUs could have a logical CPU ID after boot time.
      
      But, ACPI tables are unreliable. the number amd order of Local APIC
      entries which depends on the firmware is often inconsistent with the
      physical devices. Even if they are consistent, The disabled CPUs which
      take up some logical CPU IDs will also make the order discontinuous.
      
      Revert the part of disabled CPUs registration, keep the allocation
      logic of logical CPU IDs and also keep some code location changes.

      Revert "x86/ioapic: Restore IO-APIC irq_chip retrigger callback" · d966564f
      Linus Torvalds 提交于
      This reverts commit 020eb3da.
      
      Gabriel C reports that it causes his machine to not boot, and we haven't
      tracked down the reason for it yet.  Since the bug it fixes has been
      around for a longish time, we're better off reverting the fix for now.
      
      Gabriel says:
       "It hangs early and freezes with a lot RCU warnings.
      
        I bisected it down to :
      
        > Ruslan Ruslichenko (1):
        >       x86/ioapic: Restore IO-APIC irq_chip retrigger callback
      
        Reverting this one fixes the problem for me..
      
        The box is a PRIMERGY TX200 S5 , 2 socket , 2 x E5520 CPU(s) installed"
      
      and Ruslan and Thomas are currently stumped.

      x86/boot/e820: Remove spurious asm/e820/api.h inclusions · 5520b7e7
      Ingo Molnar 提交于
      A commonly used lowlevel x86 header, asm/pgtable.h, includes asm/e820/api.h
      spuriously, without making direct use of it.
      
      Removing it is not simple: over the years various .c code learned to rely
      on this indirect inclusion.
      
      Remove the unnecessary include - this should speed up the kernel build a bit,
      as a large header is not included anymore in totally unrelated code.
