      x86/memory_failure: Introduce {set, clear}_mce_nospec() · 284ce401
      Dan Williams authored
      Currently memory_failure() returns zero if the error was handled. On
      that result mce_unmap_kpfn() is called to zap the page out of the kernel
      linear mapping to prevent speculative fetches of potentially poisoned
      memory. However, in the case of dax mapped devmap pages the page may be
      in active permanent use by the device driver, so it cannot be unmapped
      from the kernel.
      
      Instead of marking the page not present, marking the page UC should
      be sufficient for preventing poison from being pre-fetched into the
      cache. Convert mce_unmap_pfn() to set_mce_nospec() remapping the page as
      UC, to hide it from speculative accesses.
      
      Given that that persistent memory errors can be cleared by the driver,
      include a facility to restore the page to cacheable operation,
      clear_mce_nospec().

      x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses · 510ee090
      Dan Williams authored
      In preparation for using set_memory_uc() instead set_memory_np() for
      isolating poison from speculation, teach the memtype code to sanitize
      physical addresses vs __PHYSICAL_MASK.
      
      The motivation for using set_memory_uc() for this case is to allow
      ongoing access to persistent memory pages via the pmem-driver +
      memcpy_mcsafe() until the poison is repaired.

      mm, memory_failure: Teach memory_failure() about dev_pagemap pages · 6100e34b
      Dan Williams authored
      mce: Uncorrected hardware memory error in user-access at af34214200
          {1}[Hardware Error]: It has been corrected by h/w and requires no further action
          mce: [Hardware Error]: Machine check events logged
          {1}[Hardware Error]: event severity: corrected
          Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users
          [..]
          Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed
          mce: Memory error not recovered
      
      In contrast to typical memory, dev_pagemap pages may be dax mapped. With
      dax there is no possibility to map in another page dynamically since dax
      establishes 1:1 physical address to file offset associations. Also
      dev_pagemap pages associated with NVDIMM / persistent memory devices can
      internal remap/repair addresses with poison. While memory_failure()
      assumes that it can discard typical poisoned pages and keep them
      unmapped indefinitely, dev_pagemap pages may be returned to service
      after the error is cleared.
      
      Teach memory_failure() to detect and handle MEMORY_DEVICE_HOST
      dev_pagemap pages that have poison consumed by userspace. Mark the
      memory as UC instead of unmapping it completely to allow ongoing access
      via the device driver (nd_pmem). Later, nd_pmem will grow support for
      marking the page back to WB when the error is cleared.

      filesystem-dax: Introduce dax_lock_mapping_entry() · c2a7d2a1
      Dan Williams authored
      In preparation for implementing support for memory poison (media error)
      handling via dax mappings, implement a lock_page() equivalent. Poison
      error handling requires rmap and needs guarantees that the page->mapping
      association is maintained / valid (inode not freed) for the duration of
      the lookup.
      
      In the device-dax case it is sufficient to simply hold a dev_pagemap
      reference. In the filesystem-dax case we need to use the entry lock.
      
      Export the entry lock via dax_lock_mapping_entry() that uses
      rcu_read_lock() to protect against the inode being freed, and
      revalidates the page->mapping association under xa_lock().

      mm, memory_failure: Collect mapping size in collect_procs() · ae1139ec
      Dan Williams authored
      In preparation for supporting memory_failure() for dax mappings, teach
      collect_procs() to also determine the mapping size. Unlike typical
      mappings the dax mapping size is determined by walking page-table
      entries rather than using the compound-page accounting for THP pages.

      mm, madvise_inject_error: Let memory_failure() optionally take a page reference · 23e7b5c2
      Dan Williams authored
      The madvise_inject_error() routine uses get_user_pages() to lookup the
      pfn and other information for injected error, but it does not release
      that pin. The assumption is that failed pages should be taken out of
      circulation.
      
      However, for dax mappings it is not possible to take pages out of
      circulation since they are 1:1 physically mapped as filesystem blocks,
      or device-dax capacity. They also typically represent persistent memory
      which has an error clearing capability.
      
      In preparation for adding a special handler for dax mappings, shift the
      responsibility of taking the page reference to memory_failure(). I.e.
      drop the page reference and do not specify MF_COUNT_INCREASED to
      memory_failure().

      mm, dev_pagemap: Do not clear ->mapping on final put · 2fa147bd
      Dan Williams authored
      MEMORY_DEVICE_FS_DAX relies on typical page semantics whereby ->mapping
      is only ever cleared by truncation, not final put.
      
      Without this fix dax pages may forget their mapping association at the
      end of every page pin event.
      
      Move this atypical behavior that HMM wants into the HMM ->page_free()
      callback.

      Pull selinux fix from Paul Moore:
       "One fairly straightforward patch to fix a longstanding issue where a
        process could stall while accessing files in selinuxfs and block
        everyone else due to a held mutex.
      
        The patch passes all our tests and looks to apply cleanly to your
        current tree"

      Pull block fixes from Jens Axboe:
       "Small set of fixes for this series. Mostly just minor fixes, the only
        oddball in here is the sg change.
      
        The sg change came out of the stall fix for NVMe, where we added a
        mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
        sort-of ruins that, since we'd need to account for that. That's
        actually a generic problem, since lots of drivers need to allocate SG
        lists. So this just removes support for CONFIG_SG_DEBUG, which I added
        back in 2007 and to my knowledge it was never useful.
      
        Anyway, outside of that, this pull contains:
      
         - clone of request with special payload fix (Bart)
      
         - drbd discard handling fix (Bart)
      
         - SATA blk-mq stall fix (me)
      
         - chunk size fix (Keith)
      
         - double free nvme rdma fix (Sagi)"

      Pull powerpc fixes from Michael Ellerman:
       "Two regression fixes, and a new syscall wire-up:
      
         - A fix for the recent conversion to time64_t in the powermac RTC
           routines, which caused time to go backward.
      
         - Another fix for fallout from the split PMD PTL conversion.
      
         - Wire up the new io_pgetevents() syscall.
