• 6c036527a   [PATCH] mostly_read data section ... Browse Code »

  Add a new section called ".data.read_mostly" for data items that are read
  frequently and rarely written to like cpumaps etc.

  If these maps are placed in the .data section then these frequenly read
  items may end up in cachelines with data is is frequently updated. In that
  case all processors in an SMP system must needlessly reload the cachelines
  again and again containing elements of those frequently used variables.

  The ability to share these cachelines will allow each cpu in an SMP system
  to keep local copies of those shared cachelines thereby optimizing
  performance.

• dfaa9c94b   [PATCH] profile.c: `schedule' parsing fix ... Browse Code »

  profile=schedule parsing is not quite what it should be. First, str[7] is
  'e', not ',', but then even if it did fall through, prof_on =
  SCHED_PROFILING would be clobbered inside if (get_option(...)) So a small
  amount of rearrangement is done in this patch to correct it.

  synchronize_rcu() and synchronize_sched() APIs.

  Replace a number of memory barriers with smp_ variants. This means we won't
  take the unnecessary hit on UP machines.

  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!
