Subject: [PATCH 0/8] infiniband: Remove semaphores

Hi,

These are a set of patches which removes semaphores from infiniband.
These are part of a bigger effort to eliminate all semaphores from the
linux kernel.

NB: A few semaphores which are counting ones are replaced with an open-coded
implementation by introducing a new type in 'include/rdma/ib_sa.h'. Need to
see if this can be programmed in a generic way using wait queues.

Thanks,
Binoy
