This patch makes some slight alterations to linux-kernel.cat in preparation for adding support for data-race detection to the Linux-Kernel Memory Model. The definitions of relations involved in Acquire, Release, and unlock-lock ordering are moved up earlier in the source file. The rmb relation is factored through the new R4rmb class: the class of reads to which rmb will apply. The definition of the fence relation is moved earlier, and it is split up into read- and write-fences (rmb and wmb) and all the others. This should not make any functional changes.
