      [PATCH] Standardize pxx_page macros · 46a82b2d
      Dave McCracken authored
      One of the changes necessary for shared page tables is to standardize the
      pxx_page macros.  pte_page and pmd_page have always returned the struct
      page associated with their entry, while pte_page_kernel and pmd_page_kernel
      have returned the kernel virtual address.  pud_page and pgd_page, on the
      other hand, return the kernel virtual address.
      Shared page tables needs pud_page and pgd_page to return the actual page
      structures.  There are very few actual users of these functions, so it is
      simple to standardize their usage.
      Since this is basic cleanup, I am submitting these changes as a standalone
      patch.  Per Hugh Dickins' comments about it, I am also changing the
      pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

      [PATCH] mm: pte_offset_map_lock loops · 705e87c0
      Hugh Dickins authored
      Convert those common loops using page_table_lock on the outside and
      pte_offset_map within to use just pte_offset_map_lock within instead.
      These all hold mmap_sem (some exclusively, some not), so at no level can a
      page table be whipped away from beneath them.  But whereas pte_alloc loops
      tested with the "atomic" pmd_present, these loops are testing with pmd_none,
      which on i386 PAE tests both lower and upper halves.
      That's now unsafe, so add a cast into pmd_none to test only the vital lower
      half: we lose a little sensitivity to a corrupt middle directory, but not
      enough to worry about.  It appears that i386 and UML were the only
      architectures vulnerable in this way, and pgd and pud no problem.

      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!
