Here is an implementation of an allocator that allocates blue flame registers. A blue flame register is used for generating send doorbells. A blue flame register can be used to generate either a regular doorbell or a blue flame doorbell where the data to be sent is written to the device's I/O memory hence saving the need to read the data from memory. For blue flame kind of doorbells to succeed, the blue flame register need to be mapped as write combining. The user can specify what kind of send doorbells she wishes to use. If she requested write combining mapping but that failed, the allocator will fall back to non write combining mapping and will indicate that to the user. Subsequent patches in this series will make use of this allocator.
