[Bug 715930] Re: geninitrd fails on masked vendor:device entries.

[Elan Ruusamäe]

this patch makes it accept module subid with "0x0000ffff"

this resulting these modules:
jmicron
pata_jmicron
ahci

what should be done with these? all of them be loaded?

matching modules.pcimap entries for those modules:
geninitrd/tests $ grep -E 'jmicron|pata_jmicron|ahci' modules.pcimap-2.6.33.4-1 | grep 197b
# pci module         vendor     device     subvendor  subdevice  class      class_mask driver_data
jmicron              0x0000197b 0x0000ffff 0x0000ffff 0x0000ffff 0x00010100 0x00ffff00 0x0
pata_jmicron         0x0000197b 0x0000ffff 0x0000ffff 0x0000ffff 0x00010100 0x00ffff00 0x0
ahci                 0x0000197b 0x0000ffff 0x0000ffff 0x0000ffff 0x00010601 0x00ffffff 0x0

Title:
  geninitrd fails on masked vendor:device entries.

Status in PLD Linux Distribution:
  New

Bug description:
  the new logic in /lib/geninitrd/mod-sata.sh is broken. it simply
  doesn't work for masked vendor's devices.

  e.g., for jmicorn sata/ide controlers we have masked 0xffff (all
  devices) entries:

  pata_jmicron         0x0000197b 0x0000ffff 0x0000ffff 0x0000ffff 0x00010100 0x00ffff00 0x0
  jmicron              0x0000197b 0x0000ffff 0x0000ffff 0x0000ffff 0x00010100 0x00ffff00 0x0

  in such situation the awk logic which uses equality operator won't work and return empty list of kernel modules.
  this is a serious bug.
