Merge master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6:
  [PATCH] i386: export memory more than 4G through /proc/iomem
  [PATCH] 64bit Resource: finally enable 64bit resource sizes
  [PATCH] 64bit Resource: convert a few remaining drivers to use resource_size_t where needed
  [PATCH] 64bit resource: change pnp core to use resource_size_t
  [PATCH] 64bit resource: change pci core and arch code to use resource_size_t
  [PATCH] 64bit resource: change resource core to use resource_size_t
  [PATCH] 64bit resource: introduce resource_size_t for the start and end of struct resource
  [PATCH] 64bit resource: fix up printks for resources in misc drivers
  [PATCH] 64bit resource: fix up printks for resources in arch and core code
  [PATCH] 64bit resource: fix up printks for resources in pcmcia drivers
  [PATCH] 64bit resource: fix up printks for resources in video drivers
  [PATCH] 64bit resource: fix up printks for resources in ide drivers
  [PATCH] 64bit resource: fix up printks for resources in mtd drivers
  [PATCH] 64bit resource: fix up printks for resources in pci core and hotplug drivers
  [PATCH] 64bit resource: fix up printks for resources in networks drivers
  [PATCH] 64bit resource: fix up printks for resources in sound drivers
  [PATCH] 64bit resource: C99 changes for struct resource declarations

Fixed up trivial conflict in drivers/ide/pci/cmd64x.c (the printk that
was changed by the 64-bit resources had been deleted in the meantime ;)
