The proper metric for fence utilization over several
contexts is an harmonic mean, but such calculation is
prohibitive in kernel space, so the code approximates it.

Because the approximation diverges when one context has a
very small ratio compared with the other context, this change
filter out ratios smaller that 0.01%

It's very confusing for userspace to have to deal with inconsistencies
here, and some drivers screwed this up a bit. Most just ommitted the
format list when they meant to say that only linear modifier is
allowed, but some also meant that only implied modifiers are
acceptable (because actually none of the planes registered supported
modifiers).

Now that this is all done consistently across all drivers, document
the rules and enforce it in the drm core.

In cases where the dirty linear memory range spans multiple sample sheets
in a surface, the dirty surface region is incorrectly computed.
To do this correctly and in an optimized fashion  we would have to compute
the dirty region of each sample sheet and compute the union of those
regions.

But assuming that cpu writing to a multisample surface is rather a corner
case than a common case, just set the dirty region to the full surface.

   - Two fixes for the futex syscall related to the timeout handling.

     FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and
     because it's not set the time namespace adjustment for clock
     MONOTONIC is applied wrongly.

     FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
     always a relative timeout.

   - Cleanups in the futex syscall entry points which became obvious
     when the two timeout handling bugs were fixed.

   - Cleanup of queued_write_lock_slowpath() as suggested by Linus

   - Fixup of the smp_call_function_single_async() prototype"

Pull x86 fixes from Borislav Petkov:
 "A bunch of things accumulated for x86 in the last two weeks:

   - Fix guest vtime accounting so that ticks happening while the guest
     is running can also be accounted to it. Along with a consolidation
     to the guest-specific context tracking helpers.

   - Provide for the host NMI handler running after a VMX VMEXIT to be
     able to run on the kernel stack correctly.

   - Initialize MSR_TSC_AUX when RDPID is supported and not RDTSCP (virt
     relevant - real hw supports both)

   - A code generation improvement to TASK_SIZE_MAX through the use of
     alternatives

   - The usual misc and related cleanups and improvements"

This reverts commit cd2c7545.

Alex reports that the commit causes corruption with LUKS on ext4. Revert
it for now so that this can be investigated properly.

 - A fix to avoid over-allocating the kernel's mapping on !MMU systems,
   which could lead to up to 2MiB of lost memory

 - The SiFive address extension errata only manifest on rv64, they are
   now disabled on rv32 where they are unnecessary
