    SubjectTransparent Hugepage Support #27
    http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=shortlog

    first: git clone git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git
    or first: git clone --reference linux-2.6 git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git
    later: git fetch; git checkout -f origin/master

    The tree is rebased and git pull won't work.

    Diff #26 -> #27:

    b/compound_futex | 39 ++----

    Avoid taking compound_lock.

    b/compound_get_put | 13 +-

    Take compound_lock_irqsave/irqrestore.

    b/compound_lock | 22 +++

    Add compound_lock_irqsave/irqrestore.

    b/do_swap_page-VM_FAULT_WRITE | 21 +++

    Set VM_FAULT_WRITE when taking over the page in do_swap_page.

    b/has_transparent_hugepage | 45 +++++++

    Auto disable THP if PSE not set (needed when running as Xen guest
    paravirt and on 32bit kernels with THP enabled booted on old systems
    without 2M pages).

    b/khugepaged | 7 -

    Fix khugepaged startup race condition.

    b/memcg_check_room | 88 +++++++++++++++
    b/memcg_consume_stock | 51 +++++++++
    b/memcg_oom | 34 ++++++

    memcg fixes from Johannes.

    b/pmd_mangling_x86 | 38 +++++-

    Build with CONFIG_SMP=n.

    b/remove-lumpy_reclaim | 24 ++--

    Removed one leftover of lumpy reclaim.

    b/root_anon_vma-swapin | 91 ++++++++++++++++

    Use local vma->anon_vma when taking over the page, from Rik.

    b/swapin-race-conditions | 152 +++++++++++++++++++++++++++

    Fix two theoretical swapin race conditions (one only relevant for KSM
    the other only relevant when >50% swap is full).

    b/transparent_hugepage | 21 +--

    Robustness improvement to pmd_same checks, it wasn't a bug but let's
    not relay on complex locking and hold the page pins to be sure the
    pmd_same checks are reliable.

    net-regress | 72 ------------

    removed.
