Range is already set to write-back, vesafb attempts to add a write-combining
mtrr (default for vesafb).
>> mtrr: size and base must be multiples of 4 kiB
This is a bug, vesafb attempts to add a size < PAGE_SIZE triggering
the messages below.
To eliminate the warning messages, you can add the option mtrr:2 to add a
write-back mtrr for vesafb. Or just use nomtrr option.
1. Fix algorithm for finding the best power of 2 size with mtrr_add().
2. Add option to choose the mtrr type by extending the mtrr boot option:
mtrr:n where n
0 = no mtrr (equivalent to using the nomtrr option)
1 = uncachable
2 = write back
3 = write combining (default)
4 = write through
