9e9eb7c60d Annotate int2float() as being a pure function. 
This allows gcc to fold duplicate calls into a single call.  Since
the current users do actually call it multiple times with the
same arguments, this is an obvious win.

7ff64fcaa7 Rename i2f() to int2float(), and make it global so one copy can be removed. 
Remove the copy of i2f() in r600_blit_kms.c
We rename the function to something longer now that it is a global
symbol.  This reduces the likelyhood of unintended clashes later.

This might be a candidate for inclusion inside general drm infrastructure.
However, at the moment only the radeon driver uses it.

3ce0a23d2d drm/radeon/kms: add r600 KMS support 
This adds the r600 KMS + CS support to the Linux kernel.

The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.

Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.
