Patch from Daniel Jacobowitz

vfp_put_double didn't work in a CONFIG_AEABI kernel.  By swapping
the arguments, we arrange for them to be in the same place regardless
of ABI.  I made the same change to vfp_put_float for consistency.

Patch from Daniel Jacobowitz

The fcvtds and fcvtsd instructions were generating a qnan bit pattern
for both quiet and signalling NaNs.

Patch from Daniel Jacobowitz

The fcvtsd/fcvtds emulation was left behind when the numbering of double
precision registers was changed from 0-30 to 0-15.  Both conversion
instructions were writing their results to the wrong register.  Also,
the conversion instructions should stop after the first element even
if a vector length is specified.

The VFP code can leak VFP_NAN_FLAG into the FPSCR. It doesn't correspond
to any real FPSCR bit (and overlaps one of the exception flags).

Patch from Catalin Marinas

This patch changes the double registers numbering to 0-15 from even 0-30,
in preparation for future VFP extensions. It also fixes the VFP_REG_ZERO
bug (value 16 actually represents the 8th double register with the original
numbering).

The original mcrr/mrrc on CP10 were generating FMRRS/FMSRR instead of
FMRRD/FMDRR. The patch changes to CP11 for the correct instructions.

Patch from Catalin Marinas

The NaN case was dealed with by the "exponent >= ... + 32" condition but it
was not setting the value "d" to 0.

VFP used __divdi3 64-bit division needlessly.  Convert it to use
our 64-bit by 32-bit division instead.

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!
