        We still have compat interfaces for 32bit on 64bit even with the new
        2038 safe timespec/val variants because pointer size is different. And
        for the old style timespec/val interfaces we need yet another 'compat'

      Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm
      
      Pull libnvdimm memory-failure update from Dave Jiang:
       "As it stands, memory_failure() gets thoroughly confused by dev_pagemap
        backed mappings. The recovery code has specific enabling for several
        possible page states and needs new enabling to handle poison in dax
        mappings.
      
        In order to support reliable reverse mapping of user space addresses:
      
         1/ Add new locking in the memory_failure() rmap path to prevent races
            that would typically be handled by the page lock.
      
         2/ Since dev_pagemap pages are hidden from the page allocator and the
            "compound page" accounting machinery, add a mechanism to determine
            the size of the mapping that encompasses a given poisoned pfn.
      
         3/ Given pmem errors can be repaired, change the speculatively
            accessed poison protection, mce_unmap_kpfn(), to be reversible and
            otherwise allow ongoing access from the kernel.
      
        A side effect of this enabling is that MADV_HWPOISON becomes usable
        for dax mappings, however the primary motivation is to allow the
        system to survive userspace consumption of hardware-poison via dax.
        Specifically the current behavior is:
      
           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
           <reboot>
      
        ...and with these changes:
      
           Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000
           Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption
           Memory failure: 0x20cb00: recovery action for dax page: Recovered
      
        Given all the cross dependencies I propose taking this through
        nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax
        folks"

      mm/cow: don't bother write protecting already write-protected pages · 1b2de5d0
      Linus Torvalds authored
      This is not normally noticeable, but repeated forks are unnecessarily
      expensive because they repeatedly dirty the parent page tables during
      the page table copy operation.
      
      It's trivial to just avoid write protecting the page table entry if it
      was already not writable.
      
      This patch was inspired by
      
          https://bugzilla.kernel.org/show_bug.cgi?id=200447
      
      which points to an ancient "waste time re-doing fork" issue in the
      presence of lots of signals.
      
      That bug was fixed by Eric Biederman's signal handling series
      culminating in commit c3ad2c3b ("signal: Don't restart fork when
      signals come in"), but the unnecessary work for repeated forks is still
      work just fixing, particularly since the fix is trivial.

      hpfs: remove unnecessary checks on the value of r when assigning error code · e0fcfe1f
      Colin Ian King authored
      At the point where r is being checked for different values, r is always
      going to be equal to 2 as the previous if statements jump to end or end1
      if r is not 2.  Hence the assignment to err can be simplified to just
      err an assignment without any checks on the value or r.

      Thanks for your work in this area. I still remember the first linux
      storage summit we did in Vancouver 2001, Tejun was invited to talk about
      his libata error handling work. Before that, it was basically a crap
      shoot if we recovered properly or not... A lot of water has flown under
      the bridge since then!
      
      Here's an "official" patch. Linus, can you apply it?
