           and fstrim
      
         - use SSR for warm node and enable inline_xattr by default
      
         - introduce in-memory bitmaps to check FS consistency for debugging
      
         - improve write_begin by avoiding needless read IO
      
        Bug fixes:
      
         - fix broken zone_reset behavior for SMR drive
      
         - fix wrong victim selection policy during GC
      
         - fix missing behavior when preparing discard commands

      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.

      Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button count · 522214d9
      Benjamin Tissoires authored
      INPUT_PROP_BUTTONPAD is currently only set through the platform data.
      The RMI4 header doc says that this property is there to force the
      buttonpad property, so we also need to detect it by looking at
      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:
      
        d1091c7f ("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"

      kprobes/x86: Fix kernel panic when certain exception-handling addresses are probed · 75013fb1
      Masami Hiramatsu authored
      Fix to the exception table entry check by using probed address
      instead of the address of copied instruction.
      
      This bug may cause unexpected kernel panic if user probe an address
      where an exception can happen which should be fixup by __ex_table
      (e.g. copy_from_user.)
      
      Unless user puts a kprobe on such address, this doesn't
      cause any problem.
      
      This bug has been introduced years ago, by commit:
      
        46484688 ("x86/kprobes: Fix a bug which can modify kernel code permanently").

      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"

           Tibbitts for pointing this out.
      
         - NFSv4/UDP support is off. It was never really supported, and the
           spec explicitly forbids it. We only ever left it on out of

      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.

      ALSA: timer: Reject user params with too small ticks · 71321eb3
      Takashi Iwai authored
      When a user sets a too small ticks with a fine-grained timer like
      hrtimer, the kernel tries to fire up the timer irq too frequently.
      This may lead to the condensed locks, eventually the kernel spinlock
      lockup with warnings.
      
      For avoiding such a situation, we define a lower limit of the
      resolution, namely 1ms.  When the user passes a too small tick value
      that results in less than that, the kernel returns -EINVAL now.

      ARM: mm: round the initrd reservation to page boundaries · cdcc5fa0
      Russell King authored
      Round the initrd memblock reservation to page boundaries to prevent
      other data sharing the initrd pages.  This prevents an allocation
      possibly overlapping with the initrd, which would later get trampled
      on in free_initrd_mem().
