      Pull timer update from Thomas Gleixner:
       "New defines for the compat time* types so they can be shared between
        32bit and 64bit builds. Not used yet, but merging them now allows the
        actual conversions to be merged through different maintainer trees
        without dependencies
      
        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'
        interface for both 32bit native and 32bit on 64bit"

      Pull IDA updates from Matthew Wilcox:
       "A better IDA API:
      
            id = ida_alloc(ida, GFP_xxx);
            ida_free(ida, id);
      
        rather than the cumbersome ida_simple_get(), ida_simple_remove().
      
        The new IDA API is similar to ida_simple_get() but better named.  The
        internal restructuring of the IDA code removes the bitmap
        preallocation nonsense.
      
        I hope the net -200 lines of code is convincing"

      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"
