Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * sound/pss.c
+ *
+ * The low level driver for the Personal Sound System (ECHO ESC614).
+ *
+ *
+ * Copyright (C) by Hannu Savolainen 1993-1997
+ *
+ * OSS/Free for Linux is distributed under the GNU GENERAL PUBLIC LICENSE (GPL)
+ * Version 2 (June 1991). See the "COPYING" file distributed with this software
+ * for more info.
+ *
+ *
+ * Thomas Sailer	ioctl code reworked (vmalloc/vfree removed)
+ * Alan Cox		modularisation, clean up.
+ *
+ * 98-02-21: Vladimir Michl <vladimir.michl@upol.cz>
+ *          Added mixer device for Beethoven ADSP-16 (master volume,
+ *	    bass, treble, synth), only for speakers.
+ *          Fixed bug in pss_write (exchange parameters)
+ *          Fixed config port of SB
+ *          Requested two regions for PSS (PSS mixer, PSS config)
+ *          Modified pss_download_boot
+ *          To probe_pss_mss added test for initialize AD1848
+ * 98-05-28: Vladimir Michl <vladimir.michl@upol.cz>
+ *          Fixed computation of mixer volumes
+ * 04-05-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ *          Added code that allows the user to enable his cdrom and/or 
+ *          joystick through the module parameters pss_cdrom_port and 
+ *          pss_enable_joystick.  pss_cdrom_port takes a port address as its
+ *          argument.  pss_enable_joystick takes either a 0 or a non-0 as its
+ *          argument.
+ * 04-06-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ *          Separated some code into new functions for easier reuse.  
+ *          Cleaned up and streamlined new code.  Added code to allow a user 
+ *          to only use this driver for enabling non-sound components 
+ *          through the new module parameter pss_no_sound (flag).  Added 
+ *          code that would allow a user to decide whether the driver should 
+ *          reset the configured hardware settings for the PSS board through 
+ *          the module parameter pss_keep_settings (flag).   This flag will 
+ *          allow a user to free up resources in use by this card if needbe, 
+ *          furthermore it allows him to use this driver to just enable the 
+ *          emulations and then be unloaded as it is no longer needed.  Both 
+ *          new settings are only available to this driver if compiled as a 
+ *          module.  The default settings of all new parameters are set to 
+ *          load the driver as it did in previous versions.
+ * 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ *          Added module parameter pss_firmware to allow the user to tell 
+ *          the driver where the fireware file is located.  The default 
+ *          setting is the previous hardcoded setting "/etc/sound/pss_synth".
+ * 00-03-03: Christoph Hellwig <chhellwig@infradead.org>
+ *	    Adapted to module_init/module_exit
+ * 11-10-2000: Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
+ *	    Added __init to probe_pss(), attach_pss() and probe_pss_mpu()
+ * 02-Jan-2001: Chris Rankin
+ *          Specify that this module owns the coprocessor
