      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.

      MIPS: traps.c: Verify the ISA for microMIPS RDHWR emulation · 3d50a7fb
      Maciej W. Rozycki authored
      Make sure it's the microMIPS rather than MIPS16 ISA before emulating
      microMIPS RDHWR.  Mostly needed as an optimisation for configurations
      where `cpu_has_mmips' is hardcoded to 0 and also a good measure in case
      we add further microMIPS instructions to emulate in the future, as the
      corresponding MIPS16 encoding is ADDIUSP, not supposed to trap.

      xen/events: Mask a moving irq · ff1e22e7
      Boris Ostrovsky authored
      Moving an unmasked irq may result in irq handler being invoked on both
      source and target CPUs.
      
      With 2-level this can happen as follows:
      
      On source CPU:
              evtchn_2l_handle_events() ->
                  generic_handle_irq() ->
                      handle_edge_irq() ->
                         eoi_pirq():
                             irq_move_irq(data);
      
                             /***** WE ARE HERE *****/
      
                             if (VALID_EVTCHN(evtchn))
                                 clear_evtchn(evtchn);
      
      If at this moment target processor is handling an unrelated event in
      evtchn_2l_handle_events()'s loop it may pick up our event since target's
      cpu_evtchn_mask claims that this event belongs to it *and* the event is
      unmasked and still pending. At the same time, source CPU will continue
      executing its own handle_edge_irq().
      
      With FIFO interrupt the scenario is similar: irq_move_irq() may result
      in a EVTCHNOP_unmask hypercall which, in turn, may make the event
      pending on the target CPU.
      
      We can avoid this situation by moving and clearing the event while
      keeping event masked.

      Convert straggling drivers to new six-argument get_user_pages() · cb107161
      Linus Torvalds authored
      Commit d4edcf0d ("mm/gup: Switch all callers of get_user_pages() to
      not pass tsk/mm") switched get_user_pages() callers to the simpler model
      where they no longer pass in the thread and mm pointer.  But since then
      we've merged changes to a few drivers that re-introduce use of the old
      interface.  Let's fix them up.
      
      They continued to work fine (thanks to the truly disgusting macros
      introduced in commit cde70140: "mm/gup: Overload get_user_pages()
      functions"), but cause unnecessary build noise.
