2.6.9-rc2-bk5 allyesconfig fails to build for me with gcc 3.4.1 with the 
following error : 

  CC      drivers/scsi/qla2xxx/qla_os.o
drivers/scsi/qla2xxx/qla_os.c: In function `qla2x00_queuecommand':

make[2]: *** [drivers/scsi/qla2xxx] Error 2
make[1]: *** [drivers/scsi] Error 2
make: *** [drivers] Error 2
 
Here's a patch to fix this by simply moving the function. 
An alternative fix would be to uninline the function.

Since I don't have the hardware I have only been able to compile test this 
patch, but it's fairly trivial in nature so I can't imagine anything 
breaking from this small change.
