 - The 2 patch series "pid: make sub-init creation retryable" from Oleg
   Nesterov increases the robustness of our creation of init in a new
   namespace.  By clearing away some historical cruft which is no longer
   needed.  Also some documentation fixups are provided.
 
 - The 2 patch series "selftests/fchmodat2: Error handling and general"
   from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
   selftest.
 
 - The 3 patch series "lib: polynomial: Move to math/ and clean up" from
   Andy Shevchenko does as advertised.
 
 - The 3 patch series "hung_task: Provide runtime reset interface for
   hung task detector" from Aaron Tomlin gives administrators the ability
   to zero out /proc/sys/kernel/hung_task_detect_count.
 
 - The 2 patch series "tools/getdelays: use the static UAPI headers from
   tools/include/uapi" from Thomas Weißschuh teaches getdelays to use the
   in-kernel UAPI headers rather than the system-provided ones.
 
 - The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
   from Mayank Rungta provides several cleanups and fixups to the
   hardlockup detector code and its documentation.
 
 - The 2 patch series "lib/bch: fix undefined behavior from signed
   left-shifts" from Josh Law provides a couple of small/theoretical fixes
   in the bch code.
 
 - The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
   from Junrui Luo does what is claims.
 
 - The 27 patch series "cleanup the RAID5 XOR library" from Christoph
   Hellwig is a quite far-reaching cleanup to this code.  I can't do better
   than to quote Christoph:
 
     The XOR library used for the RAID5 parity is a bit of a mess right
     now.  The main file sits in crypto/ despite not being cryptography and
     not using the crypto API, with the generic implementations sitting in
     include/asm-generic and the arch implementations sitting in an asm/
     header in theory.  The latter doesn't work for many cases, so
     architectures often build the code directly into the core kernel, or
     create another module for the architecture code.
 
     Change this to a single module in lib/ that also contains the
     architecture optimizations, similar to the library work Eric Biggers
     has done for the CRC and crypto libraries later.  After that it
     changes to better calling conventions that allow for smarter
     architecture implementations (although none is contained here yet),
     and uses static_call to avoid indirection function call overhead.
 
 - The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
   workarounds" from Kuan-Wei Chiu cleans up this library code by removing
   a hacky thing which was added for UBIFS, which UBIFS doesn't actually
   need.
 
 - The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
   Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
   for the now-fixed bugs and fixes a leak in the test itself.
 
 - The 3 patch series "kdump: Enable LUKS-encrypted dump target support
   in ARM64 and PowerPC" from Coiby Xu eenables support of the
   LUKS-encrypted device dump target on arm64 and powerpc.
 
 - The 4 patch series "ocfs2: consolidate extent list validation into
   block read callbacks" from Joseph Qi addresses ocfs2's validation of
   extent list fields - cleanup, simplification, robustness.  (Kernel test
   robot loves mounting corrupted fs images!)
