      Pull io_uring updates from Jens Axboe:
       "Here are the io_uring changes for this merge window. Light on new
        features this time around (just splice + buffer selection), lots of
        cleanups, fixes, and improvements to existing support. In particular,
        this contains:
      
         - Cleanup fixed file update handling for stack fallback (Hillf)
      
         - Re-work of how pollable async IO is handled, we no longer require
           thread offload to handle that. Instead we rely using poll to drive
           this, with task_work execution.
      
         - In conjunction with the above, allow expendable buffer selection,
           so that poll+recv (for example) no longer has to be a split
           operation.
      
         - Make sure we honor RLIMIT_FSIZE for buffered writes
      
         - Add support for splice (Pavel)

             system_call+0x5c/0x68
      
      The crash is due to NULL dereference at
      
      	test_bit(idx, ms->usage->subsection_map);
      
      due to ms->usage = NULL in pfn_section_valid()
      
      With commit d41e2f3b ("mm/hotplug: fix hot remove failure in
      SPARSEMEM|!VMEMMAP case") section_mem_map is set to NULL after
      depopulate_section_mem().  This was done so that pfn_page() can work
      correctly with kernel config that disables SPARSEMEM_VMEMMAP.  With that
      config pfn_to_page does
      
      	__section_mem_map_addr(__sec) + __pfn;
      
      where
      
        static inline struct page *__section_mem_map_addr(struct mem_section *section)
        {
      	unsigned long map = section->section_mem_map;
      	map &= SECTION_MAP_MASK;
      	return (struct page *)map;
        }
      
      Now with SPASEMEM_VMEMAP enabled, mem_section->usage->subsection_map is
      used to check the pfn validity (pfn_valid()).  Since section_deactivate
      release mem_section->usage if a section is fully deactivated,
      pfn_valid() check after a subsection_deactivate cause a kernel crash.
      
        static inline int pfn_valid(unsigned long pfn)
        {
        ...
      	return early_section(ms) || pfn_section_valid(ms, pfn);
        }
      
      where
      
        static inline int pfn_section_valid(struct mem_section *ms, unsigned long pfn)
        {
      	int idx = subsection_map_index(pfn);
      
      	return test_bit(idx, ms->usage->subsection_map);
        }
      
      Avoid this by clearing SECTION_HAS_MEM_MAP when mem_section->usage is
      freed.  For architectures like ppc64 where large pages are used for
      vmmemap mapping (16MB), a specific vmemmap mapping can cover multiple
      sections.  Hence before a vmemmap mapping page can be freed, the kernel
      needs to make sure there are no valid sections within that mapping.
      Clearing the section valid bit before depopulate_section_memap enables
      this.

      mm: fork: fix kernel_stack memcg stats for various stack implementations · 8380ce47
      Roman Gushchin authored
      Depending on CONFIG_VMAP_STACK and the THREAD_SIZE / PAGE_SIZE ratio the
      space for task stacks can be allocated using __vmalloc_node_range(),
      alloc_pages_node() and kmem_cache_alloc_node().
      
      In the first and the second cases page->mem_cgroup pointer is set, but
      in the third it's not: memcg membership of a slab page should be
      determined using the memcg_from_slab_page() function, which looks at
      page->slab_cache->memcg_params.memcg .  In this case, using
      mod_memcg_page_state() (as in account_kernel_stack()) is incorrect:
      page->mem_cgroup pointer is NULL even for pages charged to a non-root
      memory cgroup.
      
      It can lead to kernel_stack per-memcg counters permanently showing 0 on
      some architectures (depending on the configuration).
      
      In order to fix it, let's introduce a mod_memcg_obj_state() helper,
      which takes a pointer to a kernel object as a first argument, uses
      mem_cgroup_from_obj() to get a RCU-protected memcg pointer and calls
      mod_memcg_state().  It allows to handle all possible configurations
      (CONFIG_VMAP_STACK and various THREAD_SIZE/PAGE_SIZE values) without
      spilling any memcg/kmem specifics into fork.c .
      
      Note: This is a special version of the patch created for stable
      backports.  It contains code from the following two patches:
        - mm: memcg/slab: introduce mem_cgroup_from_obj()
        - mm: fork: fix kernel_stack memcg stats for various stack implementations

      hugetlb_cgroup: fix illegal access to memory · 726b7bbe
      Mina Almasry authored
      This appears to be a mistake in commit faced7e0 ("mm: hugetlb
      controller for cgroups v2").
      
      Essentially that commit does a hugetlb_cgroup_from_counter assuming that
      page_counter_try_charge has initialized counter.
      
      But if that has failed then it seems will not initialize counter, so
      hugetlb_cgroup_from_counter(counter) ends up pointing to random memory,
      causing kasan to complain.
      
      The solution is to simply use 'h_cg', instead of
      hugetlb_cgroup_from_counter(counter), since that is a reference to the
      hugetlb_cgroup anyway.  After this change kasan ceases to complain.

      drivers/base/memory.c: indicate all memory blocks as removable · 53cdc1cb
      David Hildenbrand authored
      We see multiple issues with the implementation/interface to compute
      whether a memory block can be offlined (exposed via
      /sys/devices/system/memory/memoryX/removable) and would like to simplify
      it (remove the implementation).
      
      1. It runs basically lockless. While this might be good for performance,
         we see possible races with memory offlining that will require at
         least some sort of locking to fix.
      
      2. Nowadays, more false positives are possible. No arch-specific checks
         are performed that validate if memory offlining will not be denied
         right away (and such check will require locking). For example, arm64
         won't allow to offline any memory block that was added during boot -
         which will imply a very high error rate. Other archs have other
         constraints.
      
      3. The interface is inherently racy. E.g., if a memory block is detected
         to be removable (and was not a false positive at that time), there is
         still no guarantee that offlining will actually succeed. So any
         caller already has to deal with false positives.
      
      4. It is unclear which performance benefit this interface actually
         provides. The introducing commit 5c755e9f ("memory-hotplug: add
         sysfs removable attribute for hotplug memory remove") mentioned
      
      	"A user-level agent must be able to identify which sections
      	 of memory are likely to be removable before attempting the
      	 potentially expensive operation."
      
         However, no actual performance comparison was included.
      
      Known users:
      
       - lsmem: Will group memory blocks based on the "removable" property. [1]
      
       - chmem: Indirect user. It has a RANGE mode where one can specify
                removable ranges identified via lsmem to be offlined. However,
                it also has a "SIZE" mode, which allows a sysadmin to skip the
                manual "identify removable blocks" step. [2]
      
       - powerpc-utils: Uses the "removable" attribute to skip some memory
                blocks right away when trying to find some to offline+remove.
                However, with ballooning enabled, it already skips this
                information completely (because it once resulted in many false
                negatives). Therefore, the implementation can deal with false
                positives properly already. [3]
      
      According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer
      driven from userspace via the drmgr command (powerpc-utils).  Nowadays
      it's managed in the kernel - including onlining/offlining of memory
      blocks - triggered by drmgr writing to /sys/kernel/dlpar.  So the
      affected legacy userspace handling is only active on old kernels.  Only
      very old versions of drmgr on a new kernel (unlikely) might execute
      slower - totally acceptable.
      
      With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not
      break any user space tool.  We implement a very bad heuristic now.
      Without CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report
      "not removable" as before.
      
      Original discussion can be found in [4] ("[PATCH RFC v1] mm:
      is_mem_section_removable() overhaul").
      
      Other users of is_mem_section_removable() will be removed next, so that
      we can remove is_mem_section_removable() completely.

      mm/swapfile.c: move inode_lock out of claim_swapfile · d795a90e
      Naohiro Aota authored
      claim_swapfile() currently keeps the inode locked when it is successful,
      or the file is already swapfile (with -EBUSY).  And, on the other error
      cases, it does not lock the inode.
      
      This inconsistency of the lock state and return value is quite confusing
      and actually causing a bad unlock balance as below in the "bad_swap"
      section of __do_sys_swapon().
      
      This commit fixes this issue by moving the inode_lock() and IS_SWAPFILE
      check out of claim_swapfile().  The inode is unlocked in
      "bad_swap_unlock_inode" section, so that the inode is ensured to be
      unlocked at "bad_swap".  Thus, error handling codes after the locking now
      jumps to "bad_swap_unlock_inode" instead of "bad_swap".
      
          =====================================
          WARNING: bad unlock balance detected!

      The main changes are:
      
      1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid
         having to rely on compiler to do so. Issues have been noticed on
         some compilers with padding and other oddities where the request was
         then unexpectedly rejected, from Greg Kroah-Hartman.
      
      2) Sanitize the bpf_struct_ops TCP congestion control name in order to
         avoid problematic characters such as whitespaces, from Martin KaFai Lau.

      r8169: fix PHY driver check on platforms w/o module softdeps · 2e8c339b
      Heiner Kallweit authored
      On Android/x86 the module loading infrastructure can't deal with
      softdeps. Therefore the check for presence of the Realtek PHY driver
      module fails. mdiobus_register() will try to load the PHY driver
      module, therefore move the check to after this call and explicitly
      check that a dedicated PHY driver is bound to the PHY device.

      Pull ARM DT and driver fixes from Arnd Bergmann:
       "For the devicetree files, there are a total of 20 patches, almost
        entirely for 32-bit machines:
      
         - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
           both for correctness and for style that are addressed in separate
           patches. This causes most of the changed lines of the DT updates
           this time.
      
         - More Allwinner updates fixing the identification of the security
           system on sun8i/A33, a recent regression of the A83t ethernet, and
           a few board specific issues on the TBS-A711 macine.
      
         - Several bug fixes for OMAP dts files, most notably fixing the
           timings for the NAND flash on the Nokia N900 that regressed a while
           ago after the move to configuring them from DT. Some other OMAPs
           now set the correct dma limits on the L3 bus, and a regression fix
           addresses lost Ethernet on dm814x
      
         - One incorrect setting in the newly added Raspberry Pi Zero W that
           may cause issues with the SD card controller.
      
         - A missing property on the bcm2835 firmware node caused incorrect
           DMA settings.
      
         - An old bug on the oxnas platform causing spurious interrupts is
           finally addressed.
      
         - A regression on the Exynos Midas board broke the OLED panel power
           supply.
      
         - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
           is now set to the values from the datasheet.
      
         - Some 64-bit machines use a deprecated string to identify the PSCI
           firmware.
      
        There are also several small code fixes addressing mostly serious
        issues:
      
         - Fix the sunxi rsb bus access to no longer return incorrect data
           when mixing 8 and 16 bit I/O.
      
         - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
           quirk in the ti-sysc driver
      
         - Fix a NULL pointer access from a race in the fsl dpio driver
      
         - Fix a v5.5 regression in the exynos-chipid driver that caused an
           invalid error code probing the device on non-exynos platforms
      
         - Fix an out-of-bounds access in the AMD TEE driver"
