Revision 2456e855354415bfaeb7badaa14e11b3e02c8466 authored by Thomas Gleixner on 25 December 2016, 10:38:40 UTC, committed by Thomas Gleixner on 25 December 2016, 16:21:22 UTC 
ktime: Get rid of the union
 
ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.

Get rid of the union and just keep ktime_t as simple typedef of type s64.

The conversion was done with coccinelle and some manual mopping up.
