    The powernow-k8 driver checks to see that the Performance Control/Status
    Registers are declared as FFH (functional fixed hardware) by the BIOS.
    However, this check got broken in the commit:

  • 32b154c0b   x86: ignore VM_LOCKED when determining if hugetlb-backed page tables can be shared or not ... Browse Code »

    Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13302

    On x86 and x86-64, it is possible that page tables are shared beween
    shared mappings backed by hugetlbfs. As part of this,
    page_table_shareable() checks a pair of vma->vm_flags and they must match
    if they are to be shared. All VMA flags are taken into account, including
    VM_LOCKED.

    The problem is that VM_LOCKED is cleared on fork(). When a process with a
    shared memory segment forks() to exec() a helper, there will be shared
    VMAs with different flags. The impact is that the shared segment is
    sometimes considered shareable and other times not, depending on what
    process is checking.

    What happens is that the segment page tables are being shared but the
    count is inaccurate depending on the ordering of events. As the page
    tables are freed with put_page(), bad pmd's are found when some of the
    children exit. The hugepage counters also get corrupted and the Total and
    Free count will no longer match even when all the hugepage-backed regions
    are freed. This requires a reboot of the machine to "fix".

    This patch addresses the problem by comparing all flags except VM_LOCKED
    when deciding if pagetables should be shared or not for hugetlbfs-backed
    mapping.

  • c3dc5bec0   flat: fix data sections alignment ... Browse Code »

    The flat loader uses an architecture's flat_stack_align() to align the
    stack but assumes word-alignment is enough for the data sections.

    However, on the Xtensa S6000 we have registers up to 128bit width
    which can be used from userspace and therefor need userspace stack and
    data-section alignment of at least this size.

    This patch drops flat_stack_align() and uses the same alignment that
    is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's
    not defined by the architecture.

    It also fixes m32r which was obviously kaput, aligning an
    uninitialized stack entry instead of the stack pointer.

  • ecd322c9b   [ARM] Add cmpxchg support for ARMv6+ systems (v5) ... Browse Code »

    Add cmpxchg/cmpxchg64 support for ARMv6K and ARMv7 systems
    (original patch from Catalin Marinas )

    The cmpxchg and cmpxchg64 functions can be implemented using the
    LDREX*/STREX* instructions. Since operand lengths other than 32bit are
    required, the full implementations are only available if the ARMv6K
    extensions are present (for the LDREXB, LDREXH and LDREXD instructions).

    For ARMv6, only 32-bits cmpxchg is available.

    Mathieu :

    Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes).
    Make cmpxchg64_local always available.

    Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does.

    Change since v3 :
    - Add "memory" clobbers (thanks to Nicolas Pitre)
    - removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+.

    Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not
    supported by the Linux kernel currently.

    Put back arm < v6 cmpxchg support.

  • bac4e960b   [ARM] barriers: improve xchg, bitops and atomic SMP barriers ... Browse Code »

    Mathieu Desnoyers pointed out that the ARM barriers were lacking:

    - cmpxchg, xchg and atomic add return need memory barriers on
    architectures which can reorder the relative order in which memory
    read/writes can be seen between CPUs, which seems to include recent
    ARM architectures. Those barriers are currently missing on ARM.

    - test_and_xxx_bit were missing SMP barriers.

    So put these barriers in. Provide separate atomic_add/atomic_sub
    operations which do not require barriers.
