warning in current tree...

[David Miller]

The current net-2.6.26 build warns on allmodconfig because:

WARNING: net/wireless/cfg80211: 'ieee80211_get_channel' exported twice. Previous exprort was in net/ieee80211/ieee80211.ko

Please fix this up, thanks!

Ahrg. I wasn't aware that had a similarly named function, I'll fix it,
thanks for the note.

That line looks like this:

			cpu_to_le32(MWL8K_RX_CTRL_OWNED_BY_HOST);

And MWL8K_RX_CTRL_OWNED_BY_HOST is defined like this:

#define MWL8K_RX_CTRL_OWNED_BY_HOST	0x02

I'm going to take a wild guess that Dave is building on 64-bit Sparc, and based on that I'm going to bet that the bare "0x02" is getting typed as a 64-bit integer.  My
first thought is to suggest changing "0x02" to "0x02L", but I think that would just change it to a "long" type.  IIRC, "long" would still be 64-bit on sparc64...?

What about a patch like this?
