      clean up x86 platform driver default values · 0192f175
      Linus Torvalds authored
      The updates this merge window added several bogus default enablement for
      new features.  We don't do that.  If people want new behavior, they ask
      for it.
      
      One 'default n' was also removed as pointless.  That's great, but there
      were eight other ones in the same file that were left alone.
      
      Fix it up.

      Pull x86 platform driver updates from Andy Shevchenko:
       "Here is the collected material against Platform Drivers x86 subsystem.
        It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
        activity
      
        For this cycle we have quite an update for the Dell SMBIOS driver
        including WMI work to provide an interface for SMBIOS tokens via sysfs
        and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
        split into a separate driver followed by a new WMI dispatcher. The
        latter provides a character device interface to user space.
      
        The git history also contains a merge of immutable branch from Wolfram
        Sang in order to apply a dependent fix to the Intel CherryTrail
        Battery Management driver.
      
        Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
        support is added for Intel Skylake.

      platform/x86: silead_dmi: Add silead, home-button property to some tablets · aaa40965
      Hans de Goede authored
      Add "silead,home-button" property to entries for tablets which have
      a capacitive home button (typically a windows logo on the front).
      
      This new property is checked for by the new capacitive home button
      support in the silead touchscreen driver.

      Pull clk updates from Stephen Boyd:
       "We have two changes to the core framework this time around.
      
        The first being a large change that introduces runtime PM support to
        the clk framework. Now we properly call runtime PM operations on the
        device providing a clk when the clk is in use. This helps on SoCs
        where the clks provided by a device need something to be powered on
        before using the clks, like power domains or regulators. It also helps
        power those things down when clks aren't in use.
      
        The other core change is a devm API addition for clk providers so we
        can get rid of a bunch of clk driver remove functions that are just
        doing of_clk_del_provider().
      
        Outside of the core, we have the usual addition of clk drivers and
        smattering of non-critical fixes to existing drivers. The biggest diff
        is support for Mediatek MT2712 and MT7622 SoCs, but those patches
        really just add a bunch of data.
      
        By the way, we're trying something new here where we build the tree up
        with topic branches. We plan to work this into our workflow so that we
        don't step on each other's toes, and so the fixes branch can be merged
        on an as-needed basis.
      
        Summary:

       "One of the most remarkable improvements in this cycle is, Kbuild is
        now able to cache the result of shell commands. Some variables are
        expensive to compute, for example, $(call cc-option,...) invokes the
        compiler. It is not efficient to redo this computation every time,
        even when we are not actually building anything. Kbuild creates a
        hidden file ".cache.mk" that contains invoked shell commands and their
        results. The speed-up should be noticeable.

      There is no need to #define the license of the driver, just put it in
      the MODULE_LICENSE() line directly as a text string.
      
      This allows tools that check that the module license matches the source
      code license to work properly, as there is no need to unwind the

      ipvlan: NULL pointer dereference panic in ipvlan_port_destroy · fe18da60
      Girish Moodalbail authored
      When call to register_netdevice() (called from ipvlan_link_new()) fails,
      we call ipvlan_uninit() (through ndo_uninit()) to destroy the ipvlan
      port. After returning unsuccessfully from register_netdevice() we go
      ahead and call ipvlan_port_destroy() again which causes NULL pointer
      dereference panic. Fix the issue by making ipvlan_init() and
      ipvlan_uninit() call symmetric.
      
      The ipvlan port will now be created inside ipvlan_init() and will be
      destroyed in ipvlan_uninit().

      route: also update fnhe_genid when updating a route cache · cebe84c6
      Xin Long authored
      Now when ip route flush cache and it turn out all fnhe_genid != genid.
      If a redirect/pmtu icmp packet comes and the old fnhe is found and all
      it's members but fnhe_genid will be updated.
      
      Then next time when it looks up route and tries to rebind this fnhe to
      the new dst, the fnhe will be flushed due to fnhe_genid != genid. It
      causes this redirect/pmtu icmp packet acutally not to be applied.
      
      This patch is to also reset fnhe_genid when updating a route cache.

      route: update fnhe_expires for redirect when the fnhe exists · e39d5246
      Xin Long authored
      Now when creating fnhe for redirect, it sets fnhe_expires for this
      new route cache. But when updating the exist one, it doesn't do it.
      It will cause this fnhe never to be expired.
      
      Paolo already noticed it before, in Jianlin's test case, it became
      even worse:
      
      When ip route flush cache, the old fnhe is not to be removed, but
      only clean it's members. When redirect comes again, this fnhe will
      be found and updated, but never be expired due to fnhe_expires not
      being set.
      
      So fix it by simply updating fnhe_expires even it's for redirect.

      sctp: set frag_point in sctp_setsockopt_maxseg correctly · ecca8f88
      Xin Long authored
      Now in sctp_setsockopt_maxseg user_frag or frag_point can be set with
      val >= 8 and val <= SCTP_MAX_CHUNK_LEN. But both checks are incorrect.
      
      val >= 8 means frag_point can even be less than SCTP_DEFAULT_MINSEGMENT.
      Then in sctp_datamsg_from_user(), when it's value is greater than cookie
      echo len and trying to bundle with cookie echo chunk, the first_len will
      overflow.
      
      The worse case is when it's value is equal as cookie echo len, first_len
      becomes 0, it will go into a dead loop for fragment later on. In Hangbin
      syzkaller testing env, oom was even triggered due to consecutive memory
      allocation in that loop.
      
      Besides, SCTP_MAX_CHUNK_LEN is the max size of the whole chunk, it should
      deduct the data header for frag_point or user_frag check.
      
      This patch does a proper check with SCTP_DEFAULT_MINSEGMENT subtracting
      the sctphdr and datahdr, SCTP_MAX_CHUNK_LEN subtracting datahdr when
      setting frag_point via sockopt. It also improves sctp_setsockopt_maxseg
      codes.

      Clean up the EXPERT menu (yet again).
      
      Move FHANDLE and CHECKPOINT_RESTORE into the primary EXPERT menu since
      they already depend on EXPERT.
      
      Move BPF_SYSCALL and USERFAULTFD out of the EXPERT Kconfig symbols menu
      list since they do not depend on EXPERT and were breaking the continuity
      of that menu list.
      
      Move all of the KALLSYMS Kconfig symbols to the end of the EXPERT menu.
      This separates the kernel services from the build options.
      
      This patch depends on [PATCH] pci: move PCI_QUIRKS to the PCI bus menu

      The parent_node() macro in IA64(Itanium) platform is unnecessary.

      drivers/pcmcia/sa1111_badge4.c: avoid unused function warning · d4258247
      Arnd Bergmann authored
      pcmv_setup() is only used when the badge4 driver is built-in, but not
      when it is a loadable module:
      
        drivers/pcmcia/sa1111_badge4.c:153:122: error: 'pcmv_setup' defined but not used [-Werror=unused-function]
      
      This adds an #ifdef to avoid the definition of the unused function in
      the modular case.

      mm: add infrastructure for get_user_pages_fast() benchmarking · 64c349f4
      Kirill A. Shutemov authored
      Performance of get_user_pages_fast() is critical for some workloads, but
      it's tricky to test it directly.
      
      This patch provides /sys/kernel/debug/gup_benchmark that helps with
      testing performance of it.

      sysvipc: make get_maxid O(1) again · 15df03c8
      Davidlohr Bueso authored
      For a custom microbenchmark on a 3.30GHz Xeon SandyBridge, which calls
      IPC_STAT over and over, it was calculated that, on avg the cost of
      ipc_get_maxid() for increasing amounts of keys was:
      
       10 keys: ~900 cycles
       100 keys: ~15000 cycles
       1000 keys: ~150000 cycles
       10000 keys: ~2100000 cycles
      
      This is unsurprising as maxid is currently O(n).
      
      By having the max_id available in O(1) we save all those cycles for each
      semctl(_STAT) command, the idr_find can be expensive -- which some real
      (customer) workloads actually poll on.
      
      Note that this used to be the case, until commit 7ca7e564 ("ipc:
      store ipcs into IDRs").  The cost is the extra idr_find when doing
      RMIDs, but we simply go backwards, and should not take too many
      iterations to find the new value.

      sysvipc: unteach ids->next_id for !CHECKPOINT_RESTORE · b8fd9983
      Davidlohr Bueso authored
      Patch series "sysvipc: ipc-key management improvements".
      
      Here are a few improvements I spotted while eyeballing Guillaume's
      rhashtable implementation for ipc keys.  The first and fourth patches
      are the interesting ones, the middle two are trivial.
      
      This patch (of 4):
      
      The next_id object-allocation functionality was introduced in commit
      03f59566 ("ipc: add sysctl to specify desired next object id").
      
      Given that these new entries are _only_ exported under the
      CONFIG_CHECKPOINT_RESTORE option, there is no point for the common case
      to even know about ->next_id.  As such rewrite ipc_buildid() such that
      it can do away with the field as well as unnecessary branches when
      adding a new identifier.  The end result also better differentiates both
      cases, so the code ends up being cleaner; albeit the small duplications
      regarding the default case.

      initramfs: use time64_t timestamps · e35c4c64
      Arnd Bergmann authored
      The cpio format uses a 32-bit number to encode file timestamps, which
      breaks initramfs support in 2038.  This reinterprets the timestamp as
      unsigned, to give us another 68 years and avoids breaking until 2106.
