[James S. <jsi...@us...>]

Update of /cvsroot/linux-mips/linux/arch/mips/math-emu
In directory usw-pr-cvs1:/tmp/cvs-serv18180

Modified Files:
	sp_fdp.c 
Log Message:
        FPU emulation fixes:

        o Converting a denormalized number now raises Inexact exception.

        o If rounding mode is "up", a positive denormalized double precision
        number should be converted to minimal (denormalized) single
        precision number.
