65d8defe2e PCI: label: remove #include of ACPI header to avoid warnings 
I found that including acpi/apci_drivers.h is not necessary and
introduces these warnings:

In file included from drivers/pci/pci-label.c:32:
include/acpi/acpi_drivers.h:103: warning: ‘struct acpi_device’ declared inside parameter list
include/acpi/acpi_drivers.h:103: warning: its scope is only this definition or declaration, which is probably not what you want
include/acpi/acpi_drivers.h:107: warning: ‘struct acpi_pci_root’ declared inside parameter list

6058989bad PCI: Export ACPI _DSM provided firmware instance number and string name to sysfs 
This patch exports ACPI _DSM (Device Specific Method) provided firmware
instance number and string name of PCI devices as defined by 'PCI
Firmware Specification Revision 3.1' section 4.6.7.( DSM for Naming a
PCI or PCI Express Device Under Operating Systems) to sysfs.

New files created are:
  /sys/bus/pci/devices/.../label which contains the firmware name for
the device in question, and
  /sys/bus/pci/devices/.../acpi_index which contains the firmware device type
instance for the given device.

cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/acpi_index
1
cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/label
Embedded Broadcom 5709C NIC 1

cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.1/acpi_index
2
cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.1/label
Embedded Broadcom 5709C NIC 2

The ACPI _DSM provided firmware 'instance number' and 'string name' will
be given priority if the firmware also provides 'SMBIOS type 41 device
type instance and string'.
