-Subject: hrtimer: Add support for CLOCK_MONOTONIC_RAW
-
-From: Marc Zyngier <marc.zyngier@arm.com>
-
-commit 9c808765e88efb6fa6af7e2206ef89512f1840a7 upstream.
-
-The KVM/ARM timer implementation arms a hrtimer when a vcpu is
-blocked (usually because it is waiting for an interrupt)
-while its timer is going to kick in the future.
-
-It is essential that this timer doesn't get adjusted, or the
-guest will end up being woken-up at the wrong time (NTP running
-on the host seems to confuse the hell out of some guests).
-
-In order to allow this, let's add CLOCK_MONOTONIC_RAW support
-to hrtimer (it is so far only supported for posix timers). It also
-has the (limited) benefit of fixing de0421d53bfb ("mac80211_hwsim:
-shuffle code to prepare for dynamic radios"), which already uses
-this functionnality without realizing wasn't implemented (just being
-lucky...).
