This is a refresh of my previous WEXT compat patch set.
I've actually tested these exact patches on sparc64 with a RNDIS based
USB wireless device from Linksys. I was able to perform iwconfig
commands, check iwlist, bring up the interface and use it properly.
All with 32-bit tools. I've also done an allmodconfig sanity
build check on sparc64.
The one thing I was not able to test yet is wpa_supplicant use, and
that likely doesn't work properly yet, but we can fix that on top and
these patches do not break native non-compat binaries. They do make a
lot of compat stuff work which wasn't the case before. So applying
this stuff makes sense, and we can get wpa_supplicant working if it
isn't working using follow-on patches.
The patch set starts by cleaning up the code so that we can avoid
having multiple copies of the WEXT main dispatch routines, one for
compat and one for the non-compat case.
Next, basic compat level handling of the WEXT ioctl is added, and the
equivalent code in the compat_ioctl.c file is removed.
Finally, compat IWE stream munging is added for the wireless layer.
When we get a compat WEXT ioctl request, we set a bit in the request
info blob, and the stream building helpers tip off this to format the
stream entries properly.
These patches are against net-next-2.6 and are also available as
a GIT tree at:
master.kernel.org:/pub/scm/linux/kernel/git/davem/wireless-2.6.git
John, please pull or apply as you deem appropriate.
Thanks!

Thanks, I'll look into this when I get a chance.
I want to redesign the interfaces so that the callers give
enough information to the helper routines such that the
compat stuff can be handled completely inside of the
helpers.
It is unpleasant (and error prone) to put this compat handling
at all of the call sites.

Thank you very much for testing.
I will respin my tree and look into the checkpatch warnings
so that I may make a final submission to John Linville.
Arigato gozaimasu!!
Thanks for updating the patch set!!

I'm testing these patches on my PS3. I've found a problem.
With 32-bit wireless-tools v28, the bitrates from the scan result were
wrong (with gelic/rt2x00 driver):
[root@localhost wireless_tools.28]# ./iwlist wlan3 scanning

I think the callers of iwe_stream_add_value() need to do some
preparations before the call if iocompat is needed, like the following.

Masakazu-san, thank you again for your testing and feedback.
Here is a new version of patch 12, which should fix the problems
you reported here. The idea is simple, all references to
IW_EV_LCP_LEN are replaced with calls to a new inline function
named iwe_stream_lcp_len() which returns the compat value if
necessary.
wext: Emit event stream entries correctly when compat.
Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.
