timex: use __kernel_timex internally
struct timex is not y2038 safe.
Replace all uses of timex with y2038 safe __kernel_timex.
Note that struct __kernel_timex is an ABI interface definition.
We could define a new structure based on __kernel_timex that
is only available internally instead. Right now, there isn't
a strong motivation for this as the structure is isolated to
a few defined struct timex interfaces and such a structure would
be exactly the same as struct timex.
The patch was generated by the following coccinelle script:
