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!

+  Changelog:
+
+  Mike Cruse        : mcruse@cti-ltd.com
+                    : Changes for Linux 2.0 compatibility. 
+                    : Added dev_id parameter in net_interrupt(),
+                    : request_irq() and free_irq(). Just NULL for now.
+
+  Mike Cruse        : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
+                    : in net_open() and net_close() so kerneld would know
+                    : that the module is in use and wouldn't eject the 
+                    : driver prematurely.
+
+  Mike Cruse        : Rewrote init_module() and cleanup_module using 8390.c
+                    : as an example. Disabled autoprobing in init_module(),
+                    : not a good thing to do to other devices while Linux
+                    : is running from all accounts.
+                    
+  Alan Cox          : Removed 1.2 support, added 2.1 extra counters.
+
+  David Huggins-Daines <dhd@debian.org>
+  
+  Split this off into mac89x0.c, and gutted it of all parts which are
+  not relevant to the existing CS8900 cards on the Macintosh
+  (i.e. basically the Daynaport CS and LC cards).  To be precise:
+
+    * Removed all the media-detection stuff, because these cards are
+    TP-only.
+
+    * Lobotomized the ISA interrupt bogosity, because these cards use
+    a hardwired NuBus interrupt and a magic ISAIRQ value in the card.
+
+    * Basically eliminated everything not relevant to getting the
+    cards minimally functioning on the Macintosh.
+
+  I might add that these cards are badly designed even from the Mac
+  standpoint, in that Dayna, in their infinite wisdom, used NuBus slot
+  I/O space and NuBus interrupts for these cards, but neglected to
+  provide anything even remotely resembling a NuBus ROM.  Therefore we
+  have to probe for them in a brain-damaged ISA-like fashion.
+
+  Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
+  check kmalloc and release the allocated memory on failure in
+  mac89x0_probe and in init_module
+  use local_irq_{save,restore}(flags) in net_get_stat, not just
+  local_irq_{dis,en}able()
