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 Richard Cochran says: ==================== 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. * ChangeLog ** V3 - dp83640: use timespec64 throughout per Arnd's suggestion - tilegx: use timespec64 throughout per Chris' suggestion - add Jeff's acked-bys ** V2 - use the new methods in the posix clock code right away (patch #3) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
