[Y2038] [PATCH] [RESEND] powerpc: xmon: use ktime_get_coarse_boottime64

[Arnd Bergmann]

get_monotonic_boottime() is deprecated, and may not be safe to call in
every context, as it has to read a hardware clocksource.

This changes xmon to print the time using ktime_get_coarse_boottime64()
instead, which avoids the old timespec type and the HW access.

Originally sent Jun 18, but this hasn't appeared in linux-next yet.

Resending to make sure this is still on the radar. Please apply
to the powerpc git for 4.19
