--- Changes --
-
-  Date     Programmer	Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  10-Oct-2001 SS        port to 2.4 kernel
-  02-Apr-2002 SS        Mods to use allocator as a standalone module;
-                        Merged John Roll's changes (john@xxxxxxxxxxxxxxx)
-                        to make work with multiple boards.
-  02-Jul-2002 SS        Merged James Rose's chages (rosejr@xxxxxxxxxx) to:
-                         * fix successive interrupt-driven captures
-                         * add select/poll support.
-  10-Jul-2002 GCS       Add error check when ndevices > MAXBOARDS.
-  02-Aug-2002 GCS       Fix field mode so that odd (lower) field is stored
-                        in lower half of buffer.
-  05-Aug-2005 SS        port to 2.6 kernel.
-  26-Oct-2009 SS	port to 2.6.30 kernel.
-
--- Notes --
-
-** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
- * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
-    ftp://ftp.systemy.it/pub/develop (see README.allocator)
-
- + might want to get rid of MAXboards for allocating initial buffer.
-    confusing and not necessary
-
- + in cleanup_module the MOD_IN_USE looks like it is check after it should
-
- * GFP_DMA should not be set with a PCI system (pg 291)
-
- - NJC why are only two buffers allowed? (see isr, approx line 358)

-  Date       Programmer  Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  02-Apr-2002 SS        Mods to make work with separate allocator
-                        module; Merged John Roll's mods to make work with
-                        multiple boards.
-  10-Jul-2002 GCS       Complete rewrite of setup_buffers to disallow
-                        buffers which span a 4MB boundary.
-  24-Jul-2002 SS        GPL licence.
-  30-Jul-2002 NJC       Added support for buffer loop.
-  31-Jul-2002 NJC       Complete rewrite of buffer management
-  02-Aug-2002 NJC       Including slab.h instead of malloc.h (no warning).
-                        Also, allocator_init() now returns allocator_max
-                        so cleaned up allocate_buffers() accordingly.
-  08-Aug-2005 SS        port to 2.6 kernel.
