Subject: Page cache: Replace PAGE_CACHE_xx with inline functions V2

This patchset cleans up page cache handling by replacing
open coded shifts and adds with inline function calls.

The ultimate goal is to replace all uses of PAGE_CACHE_xxx in the
kernel through the use of these functions. All the functions take
a mapping parameter. The mapping parameter is required if we want
to support large block sizes in filesystems and block devices.

Patchset against 2.6.24-rc3-mm2.

V1->V2:
- Review by Dave Chinner. Multiple improvements and fixes.
- Review by Fengguand Wu with more improvements.
