       "The main fix here addresses a kernel panic triggered on Qualcomm
        QDF2400 due to incorrect register usage in an erratum workaround
        introduced during the merge window.
      
        Summary:
      
         - Fix kernel panic on specific Qualcomm platform due to broken
           erratum workaround
      
         - Revert contiguous bit support due to TLB conflict aborts in
           simulation

      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.

      Linus Torvalds authored
      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"

        A couple changes could theoretically break working setups on upgrade.
        I don't expect complaints in practice, but they seem worth calling out
        just in case:
      
         - NFS security labels are now off by default; a new security_label
           export flag reenables it per export. But, having them on by default
           is a disaster, as it generally only makes sense if all your clients
           and servers have similar enough selinux policies. Thanks to Jason
           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
           laziness; thanks to Jeff Layton for finally fixing that"

      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.

      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

      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: 8655/1: improve NOMMU definition of pgprot_*() · e2fce0a2

      The tegra DRM driver produces a harmless warning when built for NOMMU:

      drivers/gpu/drm/tegra/gem.c:508:12: unused variable 'prot'
      
      This is because pgprot_writecombine() on ARM returns a constant and
      ignores its argument. The version in asm-generic doesn't have that
      problem, so let's use that one instead. We don't actually care
      about the value on NOMMU, and this is consistent with what some
      other architectures do.

      Nothing in this header file depends on <linux/types.h>.
      Rather, <linux/errno.h> should be included for -ENODEV.

      ARM: 8650/1: module: handle negative R_ARM_PREL31 addends correctly · 050d18d1
      Ard Biesheuvel authored
      
      
      According to the spec 'ELF for the ARM Architecture' (IHI 0044E),
      addends for R_ARM_PREL31 relocations are 31-bit signed quantities,
      so we need to sign extend the value to 32 bits before it can be used
      as an offset in the calculation of the relocated value.
      
      We have not been bitten by this because these relocations are usually
      emitted against the start of a section, which means the addends never
      assume negative values in practice. But it is a bug nonetheless, so fix
      it.

      Now that exception based address is handled dynamically for
      processors with CP15, remove Hivecs configuration in assembly.

      ARM: 8648/2: nommu: display vectors base · 58c16709
      Afzal Mohammed authored
      
      
      VECTORS_BASE displays the exception base address. Now on no-MMU as
      the exception base address is dynamically estimated, define
      VECTORS_BASE to the variable holding it.
      
      As it is the case, limit VECTORS_BASE constant definition to MMU.

      No-MMU dynamic exception base address configuration on CP15
      processors. In the case of low vectors, decision based on whether
      security extensions are enabled & whether remap vectors to RAM
      CONFIG option is selected.
      
      For no-MMU without CP15, current default value of 0x0 is retained.

      ARM: 8646/1: mmu: decouple VECTORS_BASE from Kconfig · d2ca5f24
      Afzal Mohammed authored
      
      
      For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro
      definition will suffice.
      
      For no-MMU, exception base address is dynamically determined in
      subsequent patches. To preserve bisectability, now make the
      macro applicable for no-MMU scenario too.
      
      Thanks to 0-DAY kernel test infrastructure that found the
      bisectability issue. This macro will be restricted to MMU case upon
      dynamically determining exception base address for no-MMU.
      
      Once exception address is handled dynamically for no-MMU,
      VECTORS_BASE can be removed from Kconfig.
