Rename CACHE_LINE_SIZE to PG_CACHE_LINE_SIZE.
As noted inhttp://bugs.debian.org/763098 there is a conflict betweenpostgres' definition of CACHE_LINE_SIZE and the definition by various*bsd platforms. It's debatable who has the right to define such aname, but postgres' use was only introduced in375d852 (9.4), soit seems like a good idea to rename it.Discussion: 20140930195756.GC27407@msg.df7cb.dePer complaint of Christoph Berg in the above email, although he's notthe original bug reporter.Backpatch to 9.4 where the define was introduced.
