      gma500: remove annoying deprecation warning · 166c5a6e
      Linus Torvalds authored
      
      
      In commit e4570897 ("drm/dp-helper: Move the legacy helpers to
      gma500") the legacy i2c helpers were moved to the only remaining user of
      them, the gma500 driver.  Together with that move, i2c_dp_aux_add_bus()
      was marked deprecated and started warning about its remaining use.
      
      It's now been a year and a half of annoying warning, and apparently
      nobody cares enough about gma500 to try to move it along to the more
      modern models.
      
      Get rid of the warning - if even the gma500 people don't care enough,
      then they should certainly not spam other innocent developers with a
      warning that might hide other, much more real issues.

      Merge branch 'PAGE_CACHE_SIZE-removal' · 4a2d057e
      Linus Torvalds authored
      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 ]

      mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros · 09cbfeaf
      Kirill A. Shutemov authored
      
      
      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.
      
      We have many places where PAGE_CACHE_SIZE assumed to be equal to
      PAGE_SIZE.  And it's constant source of confusion on whether
      PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
      especially on the border between fs and mm.
      
      Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
      breakage to be doable.
      
      Let's stop pretending that pages in page cache are special.  They are
      not.
      
      The changes are pretty straight-forward:
      
       - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
      
       - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
      
       - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
      
       - page_cache_get() -> get_page();
      
       - page_cache_release() -> put_page();
      
      This patch contains automated changes generated with coccinelle using
      script below.  For some reason, coccinelle doesn't patch header files.
      I've called spatch for them manually.
      
      The only adjustment after coccinelle is revert of changes to
      PAGE_CAHCE_ALIGN definition: we are going to drop it later.
      
      There are few places in the code where coccinelle didn't reach.  I'll
      fix them manually in a separate patch.  Comments and documentation also
      will be addressed with the separate patch.
