Hi,
While looking at the kernel DRM code, I've noticed that in many places
we kmalloc() memory to store the raw EDID information, whether it be
from a DDC adapter, or loaded from firmware.
Nowhere can I find where this memory is freed. It seems in several
places that we assign it into connector-
We use __fls() to find the most significant bit. Using that, the
loop can be avoided. A second trick is to use the behaviour of the
rotate instructions to expand the range of the unsigned int to float
conversion to the full 32 bits in a branchless way.
The routine is now exact up to 2^24. Above

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
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.
