Logic changes based on top of the other patches:
This set of patches changed window_handle_t from being a pointer to an
unsigned long. The unsigned long is now a simple index into socket->win[].
Going from a pointer to unsigned long should leave the user space interface
unchanged unless I'm mistaken.
This change results in code that is less error prone and a user space
interface which is much cleaner and safer. A nice side effect is that we
are also are able to remove all members except one from window_t.
[ linux@dominikbrodowski.net:
Update to 2.6.31. Also, a plain "index" to socket->win[] does not
work, as several codepaths rely on "window_handle_t" being
non-zero if used. Therefore, set the window_handle_t to the
socket->win[] index + 1. ]

Use the generic "dynamic debug" infrastructure instead of
CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To
enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and
$ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control
for the complete module "pcmcia_core", for example. For more detailled
instructions, please see Documentation/dynamic-debug-howto.txt

As a replacement to pcmcia_get_{first,next}_tuple() and
pcmcia_get_tuple_data(), three new -- and easier to use --
functions are added:
- pcmcia_get_tuple() to get the very first CIS entry of one
type.
- pcmcia_loop_tuple() to loop over all CIS entries of one type.
- pcmcia_get_mac_from_cis() to read out the hardware MAC address
from CISTPL_FUNCE.
Only a handful of drivers need these functions anyway, as most
CIS access is already handled by pcmcia_loop_config(), which
now shares the same backed (pccard_loop_tuple()) with
pcmcia_loop_tuple().
A pcmcia_get_mac_from_cis() bug noted by Komuro
<komurojun-mbn@nifty.com> has been fixed in this revision.

pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():
- All calls to pcmcia_validate_cis() had set the "function" parameter to
BIND_FN_ALL. Therefore, remove the "function" parameter and make the
parameter to pccard_read_tuple explicit.
- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
already the case for calls to CISTPL_LONGLINK_MFC.

Since we're just parsing the tuple being passed to this function, we don't

Also, remove the call to pcmcia_validate_cis() from pcmciamtd.c, since it

Make the PCMCIA core stop using class_interface to hide socket attribute
registration. This removes the associated section mismatch warnings, and
helps get to the point where that mechanism can finally be removed.
Simplify that attribute registration by using an attribute_group.

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!
