  • Add hooks to allow a paravirt implementation to track the lifetime of
    an mm. Paravirtualization requires three hooks, but only two are
    needed in common code. They are:

    arch_dup_mmap, which is called when a new mmap is created at fork

    arch_exit_mmap, which is called when the last process reference to an
    mm is dropped, which typically happens on exit and exec.

    The third hook is activate_mm, which is called from the arch-specific
    activate_mm() macro/function, and so doesn't need stub versions for
    other architectures. It's called when an mm is first used.

  • Merged cputable.h between ppc32 and ppc64. In doing this removed support
    for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
    dont compile correctly. C code should use cpu_has_feature(). This is
    based on Arnd Bergmann's initial patch.

  • Fix for a race condition when a task gets preempted by another task while
    executing the destroy_context(...) in a FEW_CONTEXTS environment.
    mm->context == NO_CONTEXT but the context_map may indicate all contexts are
    in use.

    The solution to this problem is to disable kernel preemption while
    destroying a MMU context.

  • The e200 core is a Book-E core (similar to e500) that has a unified L1 cache
    and is not cache coherent on the bus. The e200 core also adds a separate
    exception level for debug exceptions. Part of this patch helps to cleanup a
    few cases that are true for all Freescale Book-E parts, not just e500.

  • 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!
