Merge branch 'ptp-2038'

Fixed two warnings in e1000e and igb, when switching to timespec64
some printf formats started to not match.  In theses cases actually
the new type is __kernel_time_t which is __kernel_long_t which
unfortunately can be either "long" or "long long".  So to solve
this I cases the arguments to "long long".  -DaveM

====================
ptp: get ready for 2038

This series converts the core driver methods of the PTP Hardware Clock
(PHC) subsystem to use the 64 bit version of the timespec structure,
making the core API ready for the year 2038.

In addition, I reviewed how each driver and device represents the time
value at the hardware register level.  Most of the drivers are ready,
but a few will need some work before the year 2038, as shown:

   Patch   Driver
   ------------------------------------------------
   12      drivers/net/ethernet/intel/igb/igb_ptp.c
   15 ?    drivers/net/ethernet/sfc/ptp.c
   16      drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c

The commit log messages document how each driver is ready or why it is
not ready.  For patch 15, I could not easily find out the hardware
representation of the time value, and so the SFC maintainers will have
to review their low level code in order to resolve any remaining
issues.
