Subject: [PATCH] powerpc: xmon: use ktime_get_coarse_boottime64
Date:   Mon, 18 Jun 2018 11:56:24 +0200
Message-Id: <20180618095653.1538471-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
