| |
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().
