From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
Subject: include: remove pagemap.h from blkdev.h
My UEK-derived config has 1030 files depending on pagemap.h before this
change. Afterwards, just 326 files need to be rebuilt when I touch
pagemap.h. I think blkdev.h is probably included too widely, but
untangling that dependency is harder and this solves my problem. x86
allmodconfig builds, but there may be implicit include problems on other
architectures.
