* [MIPS] ieee754[sd]p_neg workaroundAtsushi Nemoto2006-02-072-8/+20
| | | | | | | | | | It looks glibc's pow() assumes an unary '-' operation for any number (including NaNs) always inverts its sign bit (though IEEE754 does not specify the sign bit for NaNs). This patch make the kernel math-emu emulates real MIPS neg.[ds] instruction. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
