Cover letter [patch 00/19] 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 Fengguand Wu with more improvements.
