Right. I'll fix it.

No, it's not "two" like the number but "to" like in "add to the group" or
"add to the pile".

Should be ((1 << I2F_MAX_BITS) - 1): 2^n == (1 << n)
Right. I'll fix it.
Use WARN_ON_ONCE here to avoid spamming the kernel output. If this is
ever hit again

Evergreen and NI blit copy was broken if the buffer maps to a rectangle
whose one dimension is 16384 (max dimension allowed by these chips).
In the mainline kernel, the problem is exposed only when buffers are
very large (1G), but it's still a problem. The problem could be exposed
for smaller buffe
