       "More fixes from testing done on the rc kernel, including more SELinux
        testing. Looking forward, lockdep found regression today in ipoib
        which is still being fixed.
      
        Summary:
      
         - Fix for SELinux on the umad SMI path. Some old hardware does not
           fill the PKey properly exposing another bug in the newer SELinux
           code.
      
         - Check the input port as we can exceed array bounds from this user
           supplied value
      
         - Users are unable to use the hash field support as they want due to
           incorrect checks on the field restrictions, correct that so the
           feature works as intended
      
         - User triggerable oops in the NETLINK_RDMA handler
      
         - cxgb4 driver fix for a bad interaction with CQ flushing in iser
           caused by patches in this merge window, and bad CQ flushing during
           normal close.
      
         - Unbalanced memalloc_noio in ipoib in an error path"

      Revert "mm: replace p??_write with pte_access_permitted in fault + gup paths" · f6f37321
      Linus Torvalds authored
      This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c.
      
      We'll probably need to revisit this, but basically we should not
      complicate the get_user_pages_fast() case, and checking the actual page
      table protection key bits will require more care anyway, since the
      protection keys depend on the exact state of the VM in question.
      
      Particularly when doing a "remote" page lookup (ie in somebody elses VM,
      not your own), you need to be much more careful than this was.  Dave
      Hansen says:
      
       "So, the underlying bug here is that we now a get_user_pages_remote()
        and then go ahead and do the p*_access_permitted() checks against the
        current PKRU. This was introduced recently with the addition of the
        new p??_access_permitted() calls.
      
        We have checks in the VMA path for the "remote" gups and we avoid
        consulting PKRU for them. This got missed in the pkeys selftests
        because I did a ptrace read, but not a *write*. I also didn't
        explicitly test it against something where a COW needed to be done"
      
      It's also not entirely clear that it makes sense to check the protection
      key bits at this level at all.  But one possible eventual solution is to
      make the get_user_pages_fast() case just abort if it sees protection key
      bits set, which makes us fall back to the regular get_user_pages() case,
      which then has a vma and can do the check there if we want to.
      
      We'll see.
      
      Somewhat related to this all: what we _do_ want to do some day is to
      check the PAGE_USER bit - it should obviously always be set for user
      pages, but it would be a good check to have back.  Because we have no
      generic way to test for it, we lost it as part of moving over from the
      architecture-specific x86 GUP implementation to the generic one in
      commit e585513b
      
       ("x86/mm/gup: Switch GUP to the generic
      get_user_page_fast() implementation").

      Currently mdio read/write takes around ~115us as the timeout
      between status check is set to 100us.
      By reducing the timeout to 1us mdio read/write takes ~15us to
      complete. This improves the link up event response.

       "Misc fixes:
      
         - fix the s2ram regression related to confusion around segment
           register restoration, plus related cleanups that make the code more
           robust
      
         - a guess-unwinder Kconfig dependency fix
      
         - an isoimage build target fix for certain tool chain combinations
      
         - instruction decoder opcode map fixes+updates, and the syncing of
           the kernel decoder headers to the objtool headers
      
         - a kmmio tracing fix
      
         - two 5-level paging related fixes

      Pull locking fixes from Ingo Molnar:
       "Misc fixes:
      
         - Fix a S390 boot hang that was caused by the lock-break logic.
           Remove lock-break to begin with, as review suggested it was
           unreasonably fragile and our confidence in its continued good
           health is lower than our confidence in its removal.
      
         - Remove the lockdep cross-release checking code for now, because of
           unresolved false positive warnings. This should make lockdep work
           well everywhere again.
      
         - Get rid of the final (and single) ACCESS_ONCE() straggler and
           remove the API from v4.15.
      
         - Fix a liblockdep build warning"
