All I wanted to do was "secal = BIN_TO_BCD(secs % 60)" ...

Has anyone else noticed the number of BCD_TO_BIN / BIN_TO_BCD
definitions?
egrep -lr -e "define (BCD_TO_BIN|BIN_TO_BCD)" linux/

Definitions are all over (in arch C files, arch includes, generic
includes, even a SCSI C file). They're all identical. They're almost all
wrapped with #ifndef to keep from clobbering each other.

My biggest problem is that they make an assignment:
#define BIN_TO_BCD(val) ((val)=(((val)/10)<<4) + (val)%10)
This makes it impossible to write code like
secal = BIN_TO_BCD(secs % 60);
because 'secs % 60' is not an lvalue.

The following patch moves all those definitions into include/linux/bcd.h
and defines BIN2BCD which doesn't make an assignment. I don't care what
it's called if that offends anyone; I just want to be able to do it. I'd
like to see BIN_TO_BCD deprecated, but maybe that's just me.

I tried to catch everything; I apologize if I missed an instance or two.
Obviously I couldn't test it all, but it builds on PPC. Comments?
