    Subject[PATCH] acpi_unlazy_tlb only on C3 entry


    Earlier patch here
    http://ussg.iu.edu/hypermail/linux/kernel/0712.2/1451.html
    was intending to add acpi_unlazy_tlb() to acpi_idle_enter_bm() routine which is
    used for C3 entry. But, some where along the way the call got added to
    acpi_idle_enter_simple() (which is C2 entry routine), probably due to identical
    context in that function. Move it back to acpi_idle_enter_bm().
