The root cause of the problem is starting hrtimer with an expiry time
already in the past can take more than 20 milliseconds to trigger the
timer function. It can be solved by forward such past timers
immediately, rather than submitting them to hrtimer_start().
In case the timer is periodic, update the target expiration and call
hrtimer_start with it.
v2: Check if the tsc deadline is already expired. Thank you Mika.
v3: Execute the past timers immediately rather than submitting them to
hrtimer_start().
v4: Rearm the periodic timer with advance_periodic_target_expiration() a
simpler version of set_target_expiration(). Thank you Paolo.

Pull rdma fixes from Doug Ledford:
"This is our first pull request of the rc cycle. It's not that it's
been overly quiet, we were just waiting on a few things before sending
this off.
For instance, the 6 patch series from Intel for the hfi1 driver had
actually been pulled in on Tuesday for a Wednesday pull request, only
to have Jason notice something I missed, so we held off for some
testing, and then on Thursday had to respin the series because the
very first patch needed a minor fix (unnecessary cast is all).
There is a sizable hns patch series in here, as well as a reasonably
largish hfi1 patch series, then all of the lines of uapi updates are
just the change to the new official Linux-OpenIB SPDX tag (a bunch of
our files had what amounts to a BSD-2-Clause + MIT Warranty statement
as their license as a result of the initial code submission years ago,
and the SPDX folks decided it was unique enough to warrant a unique
tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
and core/cache/cma updates to round out the bunch.
None of it was overly large by itself, but in the 2 1/2 weeks we've
been collecting patches, it has added up :-/.
As best I can tell, it's been through 0day (I got a notice about my
last for-next push, but not for my for-rc push, but Jason seems to
think that failure messages are prioritized and success messages not
so much). It's also been through linux-next. And yes, we did notice in
the context portion of the CMA query gid fix patch that there is a
dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
and remove it anywhere we can.
