      mm: re-architect the VM_UNPAGED logic · 6aab341e
      Linus Torvalds authored
      This replaces the (in my opinion horrible) VM_UNMAPPED logic with very
      explicit support for a "remapped page range" aka VM_PFNMAP.  It allows a
      VM area to contain an arbitrary range of page table entries that the VM
      never touches, and never considers to be normal pages.
      
      Any user of "remap_pfn_range()" automatically gets this new
      functionality, and doesn't even have to mark the pages reserved or
      indeed mark them any other way.  It just works.  As a side effect, doing
      mmap() on /dev/mem works for arbitrary ranges.
      
      Sparc update from David in the next commit.

      [PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addresses · 8b150478
      Roland Dreier authored
      Change the phys_mem_access_prot() function to take a pfn instead of an
      address.  This allows mmap64() to work on /dev/mem for addresses above 4G
      on 32-bit architectures.  We start with a pfn in mmap_mem(), so there's no
      need to convert to an address; in fact, it's actively bad, since the
      conversion can overflow when the address is above 4G.
      
      Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
      address by directly comparing to max_pfn.  Working with max_pfn instead of
      high_memory fixes page_is_ram() to give the right answer for highmem pages.

      Fix up mmap of /dev/kmem · 4bb82551
      Linus Torvalds authored
      This leaves the issue of whether we should deprecate the whole thing (or
      if we should check the whole mmap range, for that matter) open. Just do
      the minimal fix for now.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds authored
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
