Merge branch 'PAGE_CACHE_SIZE-removal' 

Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov:
 "PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
  ago with promise that one day it will be possible to implement page
  cache with bigger chunks than PAGE_SIZE.

  This promise never materialized.  And unlikely will.

  Let's stop pretending that pages in page cache are special.  They are
  not.

  The first patch with most changes has been done with coccinelle.  The
  second is manual fixups on top.

  The third patch removes macros definition"

[ I was planning to apply this just before rc2, but then I spaced out,
  so here it is right _after_ rc2 instead.

  As Kirill suggested as a possibility, I could have decided to only
  merge the first two patches, and leave the old interfaces for
  compatibility, but I'd rather get it all done and any out-of-tree
  modules and patches can trivially do the converstion while still also
  working with older kernels, so there is little reason to try to
  maintain the redundant legacy model.    - Linus ]

* PAGE_CACHE_SIZE-removal:
  mm: drop PAGE_CACHE_* and page_cache_{get,release} definition
  mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage
  mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros

which the timestamp reverts to 1970, i.e. moves backwards in time.
Currently, cramfs must be written and read with architectures of the
same endianness, and can be read only by kernels with PAGE_CACHE_SIZE
same endianness, and can be read only by kernels with PAGE_SIZE
== 4096. At least the latter of these is a bug, but it hasn't been
decided what the best fix is. For the moment if you have larger pages
you can just change the #define in mkcramfs.c, so long as you don't

from the address space. This generally corresponds to either a
truncation, punch hole or a complete invalidation of the address
space (in the latter case 'offset' will always be 0 and 'length'
will be PAGE_CACHE_SIZE). Any private data associated with the page
will be PAGE_SIZE). Any private data associated with the page
should be updated to reflect this truncation. If offset is 0 and
length is PAGE_CACHE_SIZE, then the private data should be released,
length is PAGE_SIZE, then the private data should be released,
because the page must be able to be completely discarded. This may
be done by calling the ->releasepage function, but in this case the
release MUST succeed.
