Subject: [PATCH] fix alpha boot/main.c warning

In current 2.6.23-rc1+git, make bootimage gives the following warning 
while compiling arch/alpha/boot/main.c. The patch below fixes the 
warning by casting callback argument explicitly to void*. The original 
value comes from START_ADDR macro and is clearly numeric so only cast it 
for the callback.

  CC      arch/alpha/boot/main.o
arch/alpha/boot/main.c: In function 'load':
arch/alpha/boot/main.c:135: warning: passing argument 3 of 'callback_read' makes pointer from integer without a cast
