Pull ACPI and power management fixes from Rafael J Wysocki:
 "Last-minute ACPI and power management fixes for 3.12

   - Revert epoll and select commits related to the freezer, introduced
     during the 3.11 cycle, that cause mysterious user space breakage to
     occur during resume from suspend to RAM for multiple users of
     32-bit x86 systems.  Material for 3.11.y stable kernels.

   - Revert a recent ACPI-based PCI hotplug (ACPIPHP) commit that was
     part of boot problem fixes for one machine, but turns out to cause
     issues with hotplug on Thunderbolt chains with multiple devices.
     It also turns out to be unnecessary after another fix in the same
     area that went in later.  From Mika Westerberg"
