tools/memory-model: Prepare for data-race detection
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
This should not make any functional changes.
