Rename kernel patches accepted upstream to indicate at which version they have been accepted, replacing downstream variants which what was accepted upstream. Note that some of them are fixes which will find their way to older kernel versions as well via linux-stable. No functional changes. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
