Hi, This series is a replacement for the following patch: https://patchwork.kernel.org/project/linux-pm/patch/3149540.aeNJFYEL58@kreacher/ allowing devices that only can signal PME from D3cold to be put into low-power states and signal wakeup from D3cold (if they get into it). However, the patch above works by adding a special case to pci_pme_capable() which actually is not necessary. Instead of doing that, it is sufficient to make pci_target_state() handle the case in which the device cannot signal PME from D0 consistently (patch [1/2] in this series) and make __pci_enable_wake() enable PM signaling for devices that can signal PME from D3cold (patch [2/2] in this series). Please see the patch changelogs for details. Thanks!
