[patch][0/5] powerpc: Add support to fully comply with IEEE-754 standard

[Zhu Ebony-r57400]

Hi Kumar,

I think enabling SPEFSCR[FINXE] or SPEFSCR[FRMC]=0b10/0b11 to enable FP
round interrupt will cause the exception occurring very often, which
will dramatically decrease the performance of SPE instructions. Do you
think putting an option in menuconfig to let user choose whether to
enable FP round simulation is a reasonable idea?

Thanks.
