      x86, dmi, debug: Log board name (when present) in dmesg/oops output · 84e383b3
      Naga Chumbalkar authored 
      The "Type 2" SMBIOS record that contains Board Name is not
strictly required and may be absent in the SMBIOS on some
platforms.

( Please note that Type 2 is not listed in Table 3 in Sec 6.2
  ("Required Structures and Data") of the SMBIOS v2.7
  Specification. )

Use the Manufacturer Name (aka System Vendor) name.
Print Board Name only when it is present.

Before the fix:
  (i) dmesg output: DMI: /ProLiant DL380 G6, BIOS P62 01/29/2011
 (ii) oops output:  Pid: 2170, comm: bash Not tainted 2.6.38-rc4+ #3 /ProLiant DL380 G6

After the fix:
  (i) dmesg output: DMI: HP ProLiant DL380 G6, BIOS P62 01/29/2011
 (ii) oops output:  Pid: 2278, comm: bash Not tainted 2.6.38-rc4+ #4 HP ProLiant DL380 G6

      x86, ioapic: Don't warn about non-existing IOAPICs if we have none · 678301ec
      Paul Bolle authored 
      mp_find_ioapic() prints errors like:

    ERROR: Unable to locate IOAPIC for GSI 13

if it can't find the IOAPIC that manages that specific GSI. I
see errors like that at every boot of a laptop that apparently
doesn't have any IOAPICs.

But if there are no IOAPICs it doesn't seem to be an error that
none can be found. A solution that gets rid of this message is
to directly return if nr_ioapics (still) is zero. (But keep
returning -1 in that case, so nothing breaks from this change.)

The call chain that generates this error is:

pnpacpi_allocated_resource()
    case ACPI_RESOURCE_TYPE_IRQ:
        pnpacpi_parse_allocated_irqresource()
            acpi_get_override_irq()
                 mp_find_ioapic()

      x86: Fix section mismatch in LAPIC initialization · 2fb270f3

      Additionally doing things conditionally upon smp_processor_id()
being zero is generally a bad idea, as this means CPU 0 cannot
be offlined and brought back online later again.

While there may be other places where this is done, I think adding
more of those should be avoided so that some day SMP can really
become "symmetrical".
