    Pull timer updates from Thomas Gleixner:
     "The timer and timekeeping departement delivers:
    
      Core:
    
       - The consolidation of the VDSO code into a generic library including
         the conversion of x86 and ARM64. Conversion of ARM and MIPS are en
         route through the relevant maintainer trees and should end up in
         5.4.
    
         This gets rid of the unnecessary different copies of the same code
         and brings all architectures on the same level of VDSO
         functionality.
    
       - Make the NTP user space interface more robust by restricting the
         TAI offset to prevent undefined behaviour. Includes a selftest.
    
       - Validate user input in the compat settimeofday() syscall to catch
         invalid values which would be turned into valid values by a
         multiplication overflow
    
       - Consolidate the time accessors
    
       - Small fixes, improvements and cleanups all over the place
    
      Drivers:
    
       - Support for the NXP system counter, TI davinci timer
    
       - Move the Microsoft HyperV clocksource/events code into the
         drivers/clocksource directory so it can be shared between x86 and
         ARM64.
    
       - Overhaul of the Tegra driver
    
       - Delay timer support for IXP4xx
    
       - Small fixes, improvements and cleanups as usual"
