Applying patches with 'patch' creates problems when renaming files and
changing them later in a different change in the the same patch file,
causing patch to complain that the file does not exist. So use 'git am'
instead.

Changes:

Studio. This includes support for battery status information,
keyboard, touchpad, as well as other HID devices, and performance /
platform profiles.

Recent Ubuntu mainline versions have enabled UBSAN. UBSAN has a runtime
cost and should only be enabled for debugging and testing.
Furthermore, UBSAN actively causes problems on the Surface Pro 4 and
Surface Book 1, preventing them from waking from suspend in some
instances. Disabling UBSAN should work around issue #585.
