      [PATCH] sky2: revert IRQ dance on suspend/resume · 4cbf2aa3
      Stephen Hemminger authored
      Let's just backout the IRQ hack, and for those crap machines (like some
      Sony VAIO's) can just disable MSI with the module parameter.
      
      This reverts 44ade178.

      Fix balance_dirty_page() calculations with CONFIG_HIGHMEM · dc6e29da
      Linus Torvalds authored
      This makes balance_dirty_page() always base its calculations on the
      amount of non-highmem memory in the machine, rather than try to base it
      on total memory and then falling back on non-highmem memory if the
      mapping it was writing wasn't highmem capable.
      
      This not only fixes a situation where two different writers can have
      wildly different notions about what is a "balanced" dirty state, but it
      also means that people with highmem machines don't run into an OOM
      situation when regular memory fills up with dirty pages.
      
      We used to try to handle the latter case by scaling down the dirty_ratio
      if the machine had a lot of highmem pages in page_writeback_init(), but
      it wasn't aggressive enough for some situations, and since basing the
      dirty ratio on highmem memory was broken in the first place, let's just
      stop doing so.
      
      (A variation of this theme fixed Justin Piszcz's OOM problem when
      copying an 18GB file on a RAID setup).
