[Xen-devel] [PATCH v3 04/21] x86/mm: lift PAGE_CACHE_ATTRS to page.h

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Currently all the users are within x86/mm.c. But that will change once
we split PV specific mm code to another file. Lift that to page.h
along side _PAGE_* in preparation for later patches.

No functional change. Add some spaces around "|" while moving.
