CFT: new ath hal (take 2)

[Sam Leffler]

I don't know why you are posting patches like this; they include changes 
that are not MFC'd for specific reasons.  I've already told you 
privately that the new hal has nothing to do with the issue of 
supporting the 1/2 and 1/4-rate channels in the public safety band (as 
enabled with regdomain 18).

If people want to try the new hal on a branch other than HEAD they 
should follow the directions I gave in my original mail (modulo my 
obtuseness).  I did not tell people to take the driver off head or 
anything similar.  You need ONE change; the change in rev 1.143 of 
if_ath.c that explicitly casts the bus tag and bus handle parameters in 
the call to ath_hal_attach.  The main reason for the new hal is to fix 
sparc64 support (and possibly alpha).
