Nigel Stephens cea2be4443 MIPS: Fix abs.[sd] and neg.[sd] emulation for NaN operands 
This patch ensures that the sign bit is always updated for NaN operands.

Atsushi Nemoto c5033d7803 [MIPS] ieee754[sd]p_neg workaround 
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.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
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!
