Linux v2.5.53

[Linus Torvalds]

A happy christmas to you all, and in case I'm too busy putting batteries
in the kids presents the rest of the year, here's a 2.5.53 for you.

It's got stuff all over - SCSI updates, ACPI, ia64, sparc, USB, net,
device mapper, AGP, ALSA, you name it. Meanwhile I worked mostly on the
sysenter support, we'll have to wait for glibc releases to test that out
more.

Oh, and merges with Andrew and Dave.

		Linus

Summary of changes from v2.5.52 to v2.5.53
============================================

<[e-mail]>:
  o namespace pollution in STV0680 camera driver
  o namespace pollution in ibmcam driver
  o [PKTGEN]: Mark some functions static

  o aic7xxx_old: improve usage of pci_request_regions due to device

  o Change all uses of device->request_queue (was struct, now pointer)
    Update scsi_scan so that we don't pass around a scsi_device struct
    for scanning.  Instead, we pass around a request_queue during
    scanning and create and destroy device structs as needed.  This
    allows us to have a 1:1 correlation between scsi_alloc_sdev() and
    scsi_free_sdev() calls, which we didn't have before.
