The mkc is the key for the mkey cache, hence, created in each attempt to get a cache mkey, while pcie_relaxed_ordering_enabled() is called during the setting of the mkc, but used only for cases where IB_ACCESS_RELAXED_ORDERING is set. pcie_relaxed_ordering_enabled() is an expensive call (26 us).

A previous patch replaced all irqsave locks in rxe with bh locks. This ran into problems because rdmacm has a bad habit of calling rdma verbs APIs while disabling irqs. This is not allowed during spin_unlock_bh() causing programs that use rdmacm to fail. This patch reverts the changes to locks that had this problem or got dragged into the same mess.
