       "Lots of stuff going on in the core for SPI this time around, the two
        big changes both being around time in different forms:
      
         - A rework of delay times from Alexandru Ardelean which makes the
           ways in which they are specified more consistent between drivers so
           that what's available to clients is less dependent on the hardware
           implementation.
      
         - Support for PTP timestamping of transfers from Vladimir Oltean,
           useful for use with precision clocks with SPI control interfaces.
      
         - Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers"

       - A pidfd's fdinfo file currently contains the field "Pid:\t<pid>"
         where <pid> is the pid of the process in the pid namespace of the
         procfs instance the fdinfo file for the pidfd was opened in.
      
         The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]"
         field which lists the pids of the process in all child pid namespaces
         provided the pid namespace of the procfs instance it is looked up
         under has an ancestoral relationship with the pid namespace of the
         process. If it does not 0 will be shown and no further pid namespaces
         will be listed. Tests included. (Christian Kellner)
      
       - If the process the pidfd references has already exited, print -1 for
         the Pid and NSpid fields in the pidfd's fdinfo file. Tests included.
         (me)
      
       - Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler
         that are not SIG_DFL or SIG_IGN at process creation time. This
         originated as a feature request from glibc to improve performance and
         elimate races in their posix_spawn() implementation. Tests included.
         (me)
      
       - Add support for choosing a specific pid for a process with clone3().
         This is the feature which was part of the thread update for v5.4 but
         after a discussion at LPC in Lisbon we decided to delay it for one
         more cycle in order to make the interface more generic. This has now
         done. It is now possible to choose a specific pid in a whole pid
         namespaces (sub)hierarchy instead of just one pid namespace. In order
         to choose a specific pid the caller must have CAP_SYS_ADMIN in all
         owning user namespaces of the target pid namespaces. Tests included.

      ====================
      pull-request: bpf-next 2019-11-26
      
      The following pull-request contains BPF updates for your *net-next* tree.
      
      We've added 2 non-merge commits during the last 1 day(s) which contain
      a total of 2 files changed, 14 insertions(+), 3 deletions(-).
      
      The main changes, 2 small fixes are:
      
      1) Fix libbpf out of tree compilation which complained about unknown u32
         type used in libbpf_find_vmlinux_btf_id() which needs to be __u32 instead,
         from Andrii Nakryiko.
      
      2) Follow-up fix for the prior BPF mmap series where kbuild bot complained
         about missing vmalloc_user_node_flags() for no-MMU, also from Andrii Nakryiko.

      Pull arm64 updates from Catalin Marinas:
       "Apart from the arm64-specific bits (core arch and perf, new arm64
        selftests), it touches the generic cow_user_page() (reviewed by
        Kirill) together with a macro for x86 to preserve the existing
        behaviour on this architecture.
      
        Summary:
      
         - On ARMv8 CPUs without hardware updates of the access flag, avoid
           failing cow_user_page() on PFN mappings if the pte is old. The
           patches introduce an arch_faults_on_old_pte() macro, defined as
           false on x86. When true, cow_user_page() makes the pte young before
           attempting __copy_from_user_inatomic().
      
         - Covert the synchronous exception handling paths in
           arch/arm64/kernel/entry.S to C.
      
         - FTRACE_WITH_REGS support for arm64.
      
         - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4
      
         - Several kselftest cases specific to arm64, together with a
           MAINTAINERS update for these files (moved to the ARM64 PORT entry).
      
         - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
           instructions under certain conditions.
      
         - Workaround for Cortex-A57 and A72 errata where the CPU may
           speculatively execute an AT instruction and associate a VMID with
           the wrong guest page tables (corrupting the TLB).
      
         - Perf updates for arm64: additional PMU topologies on HiSilicon
           platforms, support for CCN-512 interconnect, AXI ID filtering in
           the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.
      
         - GICv3 optimisation to avoid a heavy barrier when accessing the
           ICC_PMR_EL1 register.
      
         - ELF HWCAP documentation updates and clean-up.
      
         - SMC calling convention conduit code clean-up.
      
         - KASLR diagnostics printed during boot
      
         - NVIDIA Carmel CPU added to the KPTI whitelist
      
         - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove
           stale macro, simplify calculation in __create_pgd_mapping(), typos.
      
         - Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for
           endinanness to help with allmodconfig"

      Pull btrfs updates from David Sterba:
       "User visible changes:
         - new block group profiles: RAID1 with 3- and 4- copies
             - RAID1 in btrfs has always 2 copies, now add support for 3 and 4
             - this is an incompat feature (named RAID1C34)
             - recommended use of RAID1C3 is replacement of RAID6 profile on
               metadata, this brings a more reliable resiliency against 2
               device loss/damage
      
         - support for new checksums
             - per-filesystem, set at mkfs time
             - fast hash (crc32c successor): xxhash, 64bit digest
             - strong hashes (both 256bit): sha256 (slower, FIPS), blake2b
               (faster)
             - the blake2b module goes via the crypto tree, btrfs.ko has a
               soft dependency
      
         - speed up lseek, don't take inode locks unnecessarily, this can
           speed up parallel SEEK_CUR/SEEK_SET/SEEK_END by 80%
      
         - send:
             - allow clone operations within the same file
             - limit maximum number of sent clone references to avoid slow
               backref walking
      
         - error message improvements: device scan prints process name and PID
      
        Core changes:
         - cleanups
             - remove unique workqueue helpers, used to provide a way to avoid
               deadlocks in the workqueue code, now done in a simpler way
             - remove lots of indirect function calls in compression code
             - extent IO tree code moved out of extent_io.c
             - cleanup backup superblock handling at mount time
             - transaction life cycle documentation and cleanups
             - locking code cleanups, annotations and documentation
             - add more cold, const, pure function attributes
             - removal of unused or redundant struct members or variables
      
         - new tree-checker sanity tests
             - try to detect missing INODE_ITEM, cross-reference checks of
               DIR_ITEM, DIR_INDEX, INODE_REF, and XATTR_* items
      
         - remove own bio scheduling code (used to avoid checksum submissions
           being stuck behind other IO), replaced by cgroup controller-based
           code to allow better control and avoid priority inversions in cases
           where the custom and cgroup scheduling disagreed
      
        Fixes:
         - avoid getting stuck during cyclic writebacks
      
         - fix trimming of ranges crossing block group boundaries
      
         - fix rename exchange on subvolumes, all involved subvolumes need to

      Pull device mapper updates from Mike Snitzer:
      
       - Fix DM core to disallow stacking request-based DM on partitions.
      
       - Fix DM raid target to properly resync raidset even if bitmap needed
         additional pages.
      
       - Fix DM crypt performance regression due to use of WQ_HIGHPRI for the
         IO and crypt workqueues.
      
       - Fix DM integrity metadata layout that was aligned on 128K boundary
         rather than the intended 4K boundary (removes 124K of wasted space
         for each metadata block).
      
       - Improve the DM thin, cache and clone targets to use spin_lock_irq
         rather than spin_lock_irqsave where possible.
      
       - Fix DM thin single thread performance that was lost due to needless
         workqueue wakeups.
      
       - Fix DM zoned target performance that was lost due to excessive
         backing device checks.
      
       - Add ability to trigger write failure with the DM dust test target.
      
       - Fix whitespace indentation in drivers/md/Kconfig.
      
       - Various smalls fixes and cleanups (e.g. use struct_size, fix
         uninitialized variable, variable renames, etc).
