      x86: Print real IOAPIC version for x86-64 · 58f892e0
      由 Naga Chumbalkar 提交于 
      Fix the fact that the IOAPIC version number in the x86_64 code path always
gets assigned to 0, instead of the correct value.

Before the patch: (from "dmesg" output):

 ACPI: IOAPIC (id[0x08] address[0xfec00000] gsi_base[0])
 IOAPIC[0]: apic_id 8, version 0, address 0xfec00000, GSI 0-23     <---

 After the patch:
 ACPI: IOAPIC (id[0x08] address[0xfec00000] gsi_base[0])
 IOAPIC[0]: apic_id 8, version 32, address 0xfec00000, GSI 0-23    <---

History:

io_apic_get_version() was compiled out of the x86_64 code path in the commit
f2c2cca3:

    [PATCH] Remove APIC version/cpu capability mpparse checking/printing

    ACPI went to great trouble to get the APIC version and CPU capabilities
    of different CPUs before passing them to the mpparser. But all
    that data was used was to print it out.  Actually it even faked some data
    based on the boot cpu, not on the actual CPU being booted.

    Remove all this code because it's not needed.

    Cc: len.brown@intel.com

At the time, the IOAPIC version number was deliberately not printed
in the x86_64 code path. However, after the x86 and x86_64 files were
merged, the net result is that the IOAPIC version is printed incorrectly
in the x86_64 code path.

The patch below provides a fix. I have tested it with acpi, and with
acpi=off, and did not see any problems.

      Merge branch 'x86/cpufeature' into irq/numa · ee4c24a5
      由 Ingo Molnar 提交于 
      Merge reason: irq/numa didnt build because this commit:

  2759c328: x86: don't call read_apic_id if !cpu_has_apic

Had a dependency on x86/cpufeature changes. Pull in that
(small) branch to fix the dependency.
