      This reverts commit 97303480.
      
      Commit 97303480 ("arm64: Increase the max granular size") increased
      the cache line size to 128 to match Cavium ThunderX, apparently for some
      performance benefit which could not be confirmed. This change, however,
      has an impact on the network packet allocation in certain circumstances,
      requiring slightly over a 4K page with a significant performance
      degradation. The patch reverts L1_CACHE_SHIFT back to 6 (64-byte cache
      line).

      KVM: x86: remove APIC Timer periodic/oneshot spikes · ecf08dad
      Anthoine Bourgeois authored
      Since the commit "8003c9ae: add APIC Timer periodic/oneshot mode VMX
      preemption timer support", a Windows 10 guest has some erratic timer
      spikes.
      
      Here the results on a 150000 times 1ms timer without any load:
      	  Before 8003c9ae | After 8003c9ae
      Max           1834us          |  86000us
      Mean          1100us          |   1021us
      Deviation       59us          |    149us
      Here the results on a 150000 times 1ms timer with a cpu-z stress test:
      	  Before 8003c9ae | After 8003c9ae
      Max          32000us          | 140000us
      Mean          1006us          |   1997us
      Deviation      140us          |  11095us
      
      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.

       "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.
      
        Summary:

      Pull xfs fixes from Darrick Wong:
       "I've got one more bug fix for xfs for 4.17-rc4, which caps the amount
        of data we try to handle in one dedupe request so that userspace can't
        livelock the kernel.
      
        This series has been run through a full xfstests run during the week
        and through a quick xfstests run against this morning's master, with
        no ajor failures reported.
      
        Summary:
      
        - Cap the maximum length of a deduplication request at MAX_RW_COUNT/2
          to avoid kernel livelock due to excessively large IO requests"
