Merge branch 'timers-2038-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull time/Y2038 updates from Thomas Gleixner:

 - Consolidate SySV IPC UAPI headers

 - Convert SySV IPC to the new COMPAT_32BIT_TIME mechanism

 - Cleanup the core interfaces and standardize on the ktime_get_* naming
   convention.

 - Convert the X86 platform ops to timespec64

 - Remove the ugly temporary timespec64 hack
