  2981557cb0408e14 x86,kcfi: Fix EXPORT_SYMBOL vs kCFI

That required adding a copy of include/linux/cfi_types.h and its checking

Pull MM updates from Andrew Morton:

 - The series "Enable strict percpu address space checks" from Uros
   Bizjak uses x86 named address space qualifiers to provide
   compile-time checking of percpu area accesses.

   This has caused a small amount of fallout - two or three issues were
   reported. In all cases the calling code was found to be incorrect.

 - The series "Some cleanup for memcg" from Chen Ridong implements some
   relatively monir cleanups for the memcontrol code.

 - The series "mm: fixes for device-exclusive entries (hmm)" from David
   Hildenbrand fixes a boatload of issues which David found then using
   device-exclusive PTE entries when THP is enabled. More work is
   needed, but this makes thins better - our own HMM selftests now
   succeed.

 - The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed
   remove the z3fold and zbud implementations. They have been deprecated
   for half a year and nobody has complained.

   effects are anticipated.

   huge page sizes.

   from Tang Yizhou fixes the tracing output from the dirty page
   balancing code.

Patch series "lib/interval_tree: add some test cases and cleanup", v2.

Since rbtree/augmented tree/interval tree share similar data structure,
besides new cases for interval tree, this patch set also does cleanup for
others.


This patch (of 7):

Currently we have some tests for rbtree related data structure, e.g. 
rbtree, augmented rbtree, interval tree, in lib/ as kernel module.

To facilitate the test and debug for those fundamental data structure,
this patch enable those tests in userland.

To enable SLAB_TYPESAFE_BY_RCU for vma cache we need to ensure that
object reuse before RCU grace period is over will be detected by
lock_vma_under_rcu().

Current checks are sufficient as long as vma is detached before it is
freed.  The only place this is not currently happening is in exit_mmap(). 
Add the missing vma_mark_detached() in exit_mmap().

Another issue which might trick lock_vma_under_rcu() during vma reuse is
vm_area_dup(), which copies the entire content of the vma into a new one,
overriding new vma's vm_refcnt and temporarily making it appear as
attached.  This might trick a racing lock_vma_under_rcu() to operate on a
reused vma if it found the vma before it got reused.  To prevent this
situation, we should ensure that vm_refcnt stays at detached state (0)
when it is copied and advances to attached state only after it is added
into the vma tree.  Introduce vm_area_init_from() which preserves new
vma's vm_refcnt and use it in vm_area_dup().  Since all vmas are in
detached state with no current readers when they are freed,

lock_vma_under_rcu() will not be able to take vm_refcnt after vma got
detached even if vma is reused. vma_mark_attached() in modified to
include a release fence to ensure all stores to the vma happen before
vm_refcnt gets initialized.

Finally, make vm_area_cachep SLAB_TYPESAFE_BY_RCU. This will facilitate
vm_area_struct reuse and will minimize the number of call_rcu() calls.

Pull KVM/arm64 updates from Will Deacon:
 "New features:

   - Support for non-protected guest in protected mode, achieving near
     feature parity with the non-protected mode

   - Support for the EL2 timers as part of the ongoing NV support

   - Allow control of hardware tracing for nVHE/hVHE

  Improvements, fixes and cleanups:

   - Massive cleanup of the debug infrastructure, making it a bit less
     awkward and definitely easier to maintain. This should pave the way
     for further optimisations

   - Complete rewrite of pKVM's fixed-feature infrastructure, aligning
     it with the rest of KVM and making the code easier to follow

   - Large simplification of pKVM's memory protection infrastructure

   - Better handling of RES0/RES1 fields for memory-backed system
     registers

   - Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
     from a pretty nasty timer bug

   - Small collection of cleanups and low-impact fixes"

Pull bpf updates from Alexei Starovoitov:
 "A smaller than usual release cycle.

  The main changes are:

   - Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)

     In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
     only mode. Half of the tests are failing, since support for
     btf_decl_tag is still WIP, but this is a great milestone.

   - Convert various samples/bpf to selftests/bpf/test_progs format
     (Alexis Lothoré and Bastien Curutchet)

   - Teach verifier to recognize that array lookup with constant
     in-range index will always succeed (Daniel Xu)

   - Cleanup migrate disable scope in BPF maps (Hou Tao)

   - Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)

   - Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
     KaFai Lau)

   - Refactor verifier lock support (Kumar Kartikeya Dwivedi)

     This is a prerequisite for upcoming resilient spin lock.

   - Remove excessive 'may_goto +0' instructions in the verifier that
     LLVM leaves when unrolls the loops (Yonghong Song)

   - Remove unhelpful bpf_probe_write_user() warning message (Marco
     Elver)

   - Add fd_array_cnt attribute for prog_load command (Anton Protopopov)
