      Pull spi updates from Mark Brown:
       "The main focus of this release from a framework point of view has been
        spi-mem where we've acquired support for a few new hardware features
        which enable better performance on suitable hardware.
      
        Otherwise mostly thanks to Arnd's cleanup efforts on old platforms
        we've removed several obsolete drivers which just about balance out
        the newer drivers we've added this cycle.
      
        Summary:
      
         - Allow drivers to flag if they are unidirectional.
      
         - Support for DTR mode and hardware acceleration of dummy cycles in
           spi-mem.
      
         - Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra
           QuadSPI, Realtek RTL838x and RTL839x.
      
         - Removal of obsolete EFM32, Txx9 and SIRF Prima and Atlas drivers"

       - mostly driver updates. Bigger ones for mlxcpld and iproc. But most of

       - removal of the efm32, sirf, u300, and zte zx bus drivers because of
         platform removal. So, we have a pleasant diffstat this time.
      
       - first set of cleanups in the I2C core as preparation to increase
         maximum length of SMBus transfers to 255 (as specified in the new
         standard). Better documentation of struct i2c_msg and its flags stand
         out here.
      
       - the testunit can now respond to SMBus block process calls which is
         the testcase when implementing the above new maximum length.

           state change to be ready to send a command to the TPM chip. The bug
           has existed already since 2006, but has only made itself known in

       "We've got a good handful of patches for SELinux this time around; with
        everything passing the selinux-testsuite and applying cleanly to your
        tree as of a few minutes ago. The highlights are:
      
         - Add support for labeling anonymous inodes, and extend this new
           support to userfaultfd.
      
         - Fallback to SELinux genfs file labeling if the filesystem does not
           have xattr support. This is useful for virtiofs which can vary in
           its xattr support depending on the backing filesystem.
      
         - Classify and handle MPTCP the same as TCP in SELinux.
      
         - Ensure consistent behavior between inode_getxattr and
           inode_listsecurity when the SELinux policy is not loaded. This
           fixes a known problem with overlayfs.
      
         - A couple of patches to prune some unused variables from the SELinux
           code, mark private variables as static, and mark other variables as
           __ro_after_init or __read_mostly"

      Pull KVM updates from Paolo Bonzini:
       "x86:
      
         - Support for userspace to emulate Xen hypercalls
      
         - Raise the maximum number of user memslots
      
         - Scalability improvements for the new MMU.
      
           Instead of the complex "fast page fault" logic that is used in
           mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent,
           but the code that can run against page faults is limited. Right now
           only page faults take the lock for reading; in the future this will
           be extended to some cases of page table destruction. I hope to
           switch the default MMU around 5.12-rc3 (some testing was delayed
           due to Chinese New Year).
      
         - Cleanups for MAXPHYADDR checks
      
         - Use static calls for vendor-specific callbacks
      
         - On AMD, use VMLOAD/VMSAVE to save and restore host state
      
         - Stop using deprecated jump label APIs
      
         - Workaround for AMD erratum that made nested virtualization
           unreliable
      
         - Support for LBR emulation in the guest
      
         - Support for communicating bus lock vmexits to userspace

         - Make the nVHE EL2 object relocatable
      
         - Cleanups for concurrent translation faults hitting the same page
      
         - Support for the standard TRNG hypervisor call
      
         - A bunch of small PMU/Debug fixes
      
         - Simplification of the early init hypercall handling
      
        Non-KVM changes (with acks):
      
         - Detection of contended rwlocks (implemented only for qrwlocks,
           because KVM only needs it for x86)

      Pull scheduler updates from Ingo Molnar:
       "Core scheduler updates:
      
         - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
           preempt=none/voluntary/full boot options (default: full), to allow
           distros to build a PREEMPT kernel but fall back to close to
           PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via
           a boot time selection.
      
           There's also the /debug/sched_debug switch to do this runtime.
      
           This feature is implemented via runtime patching (a new variant of
           static calls).
      
           The scope of the runtime patching can be best reviewed by looking
           at the sched_dynamic_update() function in kernel/sched/core.c.
      
           ( Note that the dynamic none/voluntary mode isn't 100% identical,
             for example preempt-RCU is available in all cases, plus the
             preempt count is maintained in all models, which has runtime
             overhead even with the code patching. )
      
           The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast
           majority of distributions, are supposed to be unaffected.
      
         - Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
           was found via rcutorture triggering a hang. The bug is that
           rcu_idle_enter() may wake up a NOCB kthread, but this happens after
           the last generic need_resched() check. Some cpuidle drivers fix it
           by chance but many others don't.
      
           In true 2020 fashion the original bug fix has grown into a 5-patch
           scheduler/RCU fix series plus another 16 RCU patches to address the
           underlying issue of missed preemption events. These are the initial
           fixes that should fix current incarnations of the bug.
      
         - Clean up rbtree usage in the scheduler, by providing & using the
           following consistent set of rbtree APIs:
      
             partial-order; less() based:
               - rb_add(): add a new entry to the rbtree
               - rb_add_cached(): like rb_add(), but for a rb_root_cached
      
             total-order; cmp() based:
               - rb_find(): find an entry in an rbtree
               - rb_find_add(): find an entry, and add if not found
      
               - rb_find_first(): find the first (leftmost) matching entry
               - rb_next_match(): continue from rb_find_first()
               - rb_for_each(): iterate a sub-tree using the previous two
      
         - Improve the SMP/NUMA load-balancer: scan for an idle sibling in a
           single pass. This is a 4-commit series where each commit improves
           one aspect of the idle sibling scan logic.
      
         - Improve the cpufreq cooling driver by getting the effective CPU
           utilization metrics from the scheduler
      
         - Improve the fair scheduler's active load-balancing logic by
           reducing the number of active LB attempts & lengthen the
           load-balancing interval. This improves stress-ng mmapfork
           performance.
      
         - Fix CFS's estimated utilization (util_est) calculation bug that can
           result in too high utilization values
      
        Misc updates & fixes:
      
         - Fix the HRTICK reprogramming & optimization feature
      
         - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
      
         - Reduce dl_add_task_root_domain() overhead
      
         - Fix uprobes refcount bug
      
         - Process pending softirqs in flush_smp_call_function_from_idle()
      
         - Clean up task priority related defines, remove *USER_*PRIO and
           USER_PRIO()
      
         - Simplify the sched_init_numa() deduplication sort
      
         - Documentation updates
      
         - Fix EAS bug in update_misfit_status(), which degraded the quality
           of energy-balancing

      Pull io_uring updates from Jens Axboe:
       "Highlights from this cycles are things like request recycling and
        task_work optimizations, which net us anywhere from 10-20% of speedups
        on workloads that mostly are inline.
      
        This work was originally done to put io_uring under memcg, which adds
        considerable overhead. But it's a really nice win as well. Also worth
        highlighting is the LOOKUP_CACHED work in the VFS, and using it in
        io_uring. Greatly speeds up the fast path for file opens.
      
        Summary:
      
         - Put io_uring under memcg protection. We accounted just the rings
           themselves under rlimit memlock before, now we account everything.
      
         - Request cache recycling, persistent across invocations (Pavel, me)
      
         - First part of a cleanup/improvement to buffer registration (Bijan)
      
         - SQPOLL fixes (Hao)
      
         - File registration NULL pointer fixup (Dan)
      
         - LOOKUP_CACHED support for io_uring
      
         - Disable /proc/thread-self/ for io_uring, like we do for /proc/self
      
         - Add Pavel to the io_uring MAINTAINERS entry
      
         - Tons of code cleanups and optimizations (Pavel)
      
         - Support for skip entries in file registration (Noah)"
