git cherry tells me that the following five commits are the difference
between the two branches.

934f85e8bfdbab9f3910d03f670799331f870444 x86/irq, ACPI: Implement ACPI 
driver to support IOAPIC hotplug

4edc52a55f82ea26b59e801e6907c49bd1615fb1 intel_idle: Add support for the 
Airmont Core in the Cherrytrail and Braswell SOCs

423e98721e048f6c7b925a75448f6c4ecb2b5b69 ACPI: Introduce 
has_acpi_companion()

468bad4f7a6f428d010f53d7d9a2c5772ee3552d dmaengine: dw: Split device_control

931304a6567e6d47914b43ff9af1be697c0dbd8a dmaengine: dw: provide DMA 
capabilities

reverting just these produces an identical branch to the one you
sent, so I've opted for the smaller set of reverts.

Build testing passed on qemux86-64, so I'll go forward with this.
