      kasan, sched/headers: Uninline kasan_enable/disable_current() · af8601ad
      Ingo Molnar authored
      <linux/kasan.h> is a low level header that is included early
      in affected kernel headers. But it includes <linux/sched.h>
      which complicates the cleanup of sched.h dependencies.
      But kasan.h has almost no need for sched.h: its only use of
      scheduler functionality is in two inline functions which are
      not used very frequently - so uninline kasan_enable_current()
      and kasan_disable_current().
      Also add a <linux/sched.h> dependency to a .c file that depended
      on kasan.h including it.
      This paves the way to remove the <linux/sched.h> include from kasan.h.

      mm/vmacache, sched/headers: Introduce 'struct vmacache' and move it from... · 314ff785

      mm/vmacache, sched/headers: Introduce 'struct vmacache' and move it from <linux/sched.h> to <linux/mm_types>
      The <linux/sched.h> header includes various vmacache related defines,
      which are arguably misplaced.
      Move them to mm_types.h and minimize the sched.h impact by putting
      all task vmacache state into a new 'struct vmacache' structure.
      No change in functionality.

      sched/headers, cgroups: Remove the threadgroup_change_*() wrappery · 780de9dd
      Ingo Molnar authored
      threadgroup_change_begin()/end() is a pointless wrapper around
      cgroup_threadgroup_change_begin()/end(), minus a might_sleep()
      in the !CONFIG_CGROUPS=y case.
      Remove the wrappery, move the might_sleep() (the down_read()
      already has a might_sleep() check).
      This debloats <linux/sched.h> a bit and simplifies this API.
      Update all call sites.
      No change in functionality.

      rcu: Separate the RCU synchronization types and APIs into <linux/rcupdate_wait.h> · f9411ebe
      Ingo Molnar authored
      So rcupdate.h is a pretty complex header, in particular it includes
      <linux/completion.h> which includes <linux/wait.h> - creating a
      dependency that includes <linux/wait.h> in <linux/sched.h>,
      which prevents the isolation of <linux/sched.h> from the derived
      <linux/wait.h> header.
      Solve part of the problem by decoupling rcupdate.h from completions:
      this can be done by separating out the rcu_synchronize types and APIs,
      and updating their usage sites.
      Since this is a mostly RCU-internal types this will not just simplify
      <linux/sched.h>'s dependencies, but will make all the hundreds of
      .c files that include rcupdate.h but not completions or wait.h build
      ( For rcutiny this means that two dependent APIs have to be uninlined,
        but that shouldn't be much of a problem as they are rare variants. )

      sched/core: Remove the tsk_nr_cpus_allowed() wrapper · 4b53a341
      Ingo Molnar authored
      tsk_nr_cpus_allowed() too is a pretty pointless wrapper that
      is not used consistently and which makes the code both harder
      to read and longer as well.
      So remove it - this also shrinks <linux/sched.h> a bit.

      sched/core: Remove the tsk_cpus_allowed() wrapper · 0c98d344
      Ingo Molnar authored
      So the original intention of tsk_cpus_allowed() was to 'future-proof'
      the field - but it's pretty ineffectual at that, because half of
      the code uses ->cpus_allowed directly ...
      Also, the wrapper makes the code longer than the original expression!
      So just get rid of it. This also shrinks <linux/sched.h> a bit.

      sched/core: Convert ___assert_task_state() link time assert to BUILD_BUG_ON() · c930b2c0
      Ingo Molnar authored
      The length of TASK_STATE_TO_CHAR_STR was still checked using the old
      link-time manual error method - convert it to BUILD_BUG_ON(). This
      has a couple of advantages:
       - it's more obvious what's going on
       - it reduces the size and complexity of <linux/sched.h>
       - BUILD_BUG_ON() will fail during compilation, with a clearer
         error message than the link time assert.

      objtool, modules: Discard objtool annotation sections for modules · e390f9a9
      Josh Poimboeuf authored
      The '__unreachable' and '__func_stack_frame_non_standard' sections are
      only used at compile time.  They're discarded for vmlinux but they
      should also be discarded for modules.
      Since this is a recurring pattern, prefix the section names with
      ".discard.".  It's a nice convention and vmlinux.lds.h already discards
      such sections.
      Also remove the 'a' (allocatable) flag from the __unreachable section
      since it doesn't make sense for a discarded section.

      the exported buttons count.

      objtool, compiler.h: Fix __unreachable section relocation size · 55149d06
      Josh Poimboeuf authored
      Linus reported the following commit broke module loading on his laptop:
       ("objtool: Improve detection of BUG() and other dead ends")
      It showed errors like the following:
        module: overflow in relocation type 10 val ffffffffc02afc81
        module: 'nvme' likely not compiled with -mcmodel=kernel
      The problem is that the __unreachable section addresses are stored using
      the '.long' asm directive, which isn't big enough for .text section
      kernel addresses.  Use relative addresses instead:
        ".long %c0b - .\t\n"

      Pull IDR rewrite from Matthew Wilcox:
       "The most significant part of the following is the patch to rewrite the
        IDR & IDA to be clients of the radix tree. But there's much more,
        including an enhancement of the IDA to be significantly more space
        efficient, an IDR & IDA test suite, some improvements to the IDR API
        (and driver changes to take advantage of those improvements), several
        improvements to the radix tree test suite and RCU annotations.
        The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree
        for most of the last cycle. Coupled with the IDR test suite, I feel
        pretty confident that any remaining bugs are quite hard to hit. 0-day
        did a great job of watching my git tree and pointing out problems; as
        it hit them, I added new test-cases to be sure not to be caught the
        same way twice"
      Willy goes on to expand a bit on the IDR rewrite rationale:
       "The radix tree and the IDR use very similar data structures.
        Merging the two codebases lets us share the memory allocation pools,
        and results in a net deletion of 500 lines of code. It also opens up
        the possibility of exposing more of the features of the radix tree to
        users of the IDR (and I have some interesting patches along those
        lines waiting for 4.12)
        It also shrinks the size of the 'struct idr' from 40 bytes to 24 which
        will shrink a fair few data structures that embed an IDR"

      ALSA: seq: Fix link corruption by event error handling · f3ac9f73
      Takashi Iwai authored
      The sequencer FIFO management has a bug that may lead to a corruption
      (shortage) of the cell linked list.  When a sequencer client faces an
      error at the event delivery, it tries to put back the dequeued cell.
      When the first queue was put back, this forgot the tail pointer
      tracking, and the link will be screwed up.
      Although there is no memory corruption, the sequencer client may stall
      forever at exit while flushing the pending FIFO cells in
      snd_seq_pool_done(), as spotted by syzkaller.
      This patch addresses the missing tail pointer tracking at
      snd_seq_fifo_cell_putback().  Also the patch makes sure to clear the
      cell->enxt pointer at snd_seq_fifo_event_in() for avoiding a similar
      mess-up of the FIFO linked list.

      ALSA: ctxfi: Fallback DMA mask to 32bit · 15c75b09
      Takashi Iwai authored
      Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit
      architectures, and bails out if it fails.  This causes a problem on
      some platforms since the 64bit DMA isn't always guaranteed.  We should
      fall back to the default 32bit DMA when 64bit DMA fails.
      Fixes: 6d74b86d
