      [IA64] rework memory attribute aliasing · 32e62c63
      Bjorn Helgaas 提交于
      This closes a couple holes in our attribute aliasing avoidance scheme:
      
        - The current kernel fails mmaps of some /dev/mem MMIO regions because
          they don't appear in the EFI memory map.  This keeps X from working
          on the Intel Tiger box.
      
        - The current kernel allows UC mmap of the 0-1MB region of
          /sys/.../legacy_mem even when the chipset doesn't support UC
          access.  This causes an MCA when starting X on HP rx7620 and rx8620
          boxes in the default configuration.
      
      There's more detail in the Documentation/ia64/aliasing.txt file this
      adds, but the general idea is that if a region might be covered by
      a granule-sized kernel identity mapping, any access via /dev/mem or
      mmap must use the same attribute as the identity mapping.
      
      Otherwise, we fall back to using an attribute that is supported
      according to the EFI memory map, or to using UC if the EFI memory
      map doesn't mention the region.

      Linux-2.6.12-rc2 · 1da177e4

      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!
