 	Special thanks to Matt Sottek.  I did the "guts", he
 	did the "brains" and all the testing.

-Change history:
-
-	Version 1.0.0:
-	* Merge Intel, AMD, VIA RNG drivers into one.
-	  Further changelog in BitKeeper.
-
-	Version 0.9.8:
-	* Support other i8xx chipsets by adding 82801E detection
-	* 82801DB detection is the same as for 82801CA.
-
-	Version 0.9.7:
-	* Support other i8xx chipsets too (by adding 82801BA(M) and
-	  82801CA(M) detection)
-
-	Version 0.9.6:
-	* Internal driver cleanups, prep for 1.0.0 release.
-
-	Version 0.9.5:
-	* Rip out entropy injection via timer.  It never ever worked,
-	  and a better solution (rngd) is now available.
-
-	Version 0.9.4:
-	* Fix: Remove request_mem_region
-	* Fix: Horrible bugs in FIPS calculation and test execution
-
-	Version 0.9.3:
-	* Clean up rng_read a bit.
-	* Update i810_rng driver Web site URL.
-	* Increase default timer interval to 4 samples per second.
-	* Abort if mem region is not available.
-	* BSS zero-initialization cleanup.
-	* Call misc_register() from rng_init_one.
-	* Fix O_NONBLOCK to occur before we schedule.
-
-	Version 0.9.2:
-	* Simplify open blocking logic
-
-	Version 0.9.1:
-	* Support i815 chipsets too (Matt Sottek)
-	* Fix reference counting when statically compiled (prumpf)
-	* Rewrite rng_dev_read (prumpf)
-	* Make module races less likely (prumpf)
-	* Small miscellaneous bug fixes (prumpf)
-	* Use pci table for PCI id list
-
-	Version 0.9.0:
-	* Don't register a pci_driver, because we are really
-	  using PCI bridge vendor/device ids, and someone
-	  may want to register a driver for the bridge. (bug fix)
-	* Don't let the usage count go negative (bug fix)
-	* Clean up spinlocks (bug fix)
-	* Enable PCI device, if necessary (bug fix)
-	* iounmap on module unload (bug fix)
-	* If RNG chrdev is already in use when open(2) is called,
-	  sleep until it is available.
-	* Remove redundant globals rng_allocated, rng_use_count
-	* Convert numeric globals to unsigned
-	* Module unload cleanup
-
-	Version 0.6.2:
-	* Clean up spinlocks.  Since we don't have any interrupts
-	  to worry about, but we do have a timer to worry about,
-	  we use spin_lock_bh everywhere except the timer function
-	  itself.
-	* Fix module load/unload.
-	* Fix timer function and h/w enable/disable logic
-	* New timer interval sysctl
-	* Clean up sysctl names
