sparc32: Kill off software 32-bit multiply/divide routines.
For the explicit calls to .udiv/.umul in assembler, I made a mechanical (read as: safe) transformation. I didn't attempt to make any simplifications. In particular, __ndelay and __udelay can be simplified significantly. Some of the %y reads are unnecessary and these routines have no need any longer for allocating a register window, they can be leaf functions. Signed-off-by: David S. Miller <davem@davemloft.net>
