      s390/3215: partially revert tty close handling fix · 6673cd0b
      Heiko Carstens authored
      Partially revert ae289dc1 "s390/3215: fix tty close handling", since this
      leads sometimes to hanging agetty processes and therefore systems that get
      stuck while starting.
      
      This was magically fixed (bisected) by a common code patch from Alan Cox:
      36b3c070 "tty: Move the handling of the tty release logic", however it was
      unrelated.
      
      Since the removed code worked for a decade, nobody knows anymore why it was
      in there in the first place and debugging the observed hang is non-trivial
      (at least for me :) ), let's just re-add the removed code before we see
      other side effects.

      s390/irq: remove split irq fields from /proc/stat · 420f42ec
      Heiko Carstens authored
      Now that irq sum accounting for /proc/stat's "intr" line works again we
      have the oddity that the sum field (first field) contains only the sum
      of the second (external irqs) and third field (I/O interrupts).
      The reason for that is that these two fields are already sums of all other
      fields. So if we would sum up everything we would count every interrupt
      twice.
      This is broken since the split interrupt accounting was merged two years
      ago: 052ff461 "[S390] irq: have detailed
      statistics for interrupt types".
      To fix this remove the split interrupt fields from /proc/stat's "intr"
      line again and only have them in /proc/interrupts.
      
      This restores the old behaviour, seems to be the only sane fix and mimics
      a behaviour from other architectures where /proc/interrupts also contains
      more than /proc/stat's "intr" line does.

      s390/irq: enable irq sum accounting for /proc/stat again · add9bde2
      Heiko Carstens authored
      For more than two years, since f2c66cd8
      "/proc/stat: scalability of irq num per cpu" the output of /proc/stat is
      broken.
      The first field in the "intr" line should contain the sum of all interrupts,
      however since the above mentioned change it is always zero.
      
      The reason for that is that a per cpu irq sum variable had been introduced
      which got incremented when calling kstat_incr_irqs_this_cpu(). However
      on s390 we directly incremented only the per cpu per irq counter by accessing
      the array element via kstat_cpu(smp_processor_id()).irqs[...].
      So fix this and use the kstat_incr_irqs_this_cpu() wrapper which increments
      both: the per cpu per irq counter and the per cpu irq sum counter.

      s390/debug: Fix s390dbf lockdep problem in debug_(un)register_view() · 5a334c08
      Michael Holzheu authored
      The debug_register/unregister_view() functions call debugfs_remove()
      while holding the debug_info spinlock. Because debugfs_remove() takes
      a mutex and therefore can sleep this is not allowed. To fix the problem
      we give up the debug_info lock before calling debugfs_remove().
      
      The following shows the lockdep message:

      sctp: fix Kconfig bug in default cookie hmac selection · 36a25de2
      Alex Elder authored
      Commit 0d0863b0 ("sctp: Change defaults on cookie hmac selection")
      added a "choice" to the sctp Kconfig file.  It introduced a bug which
      led to an infinite loop when while running "make oldconfig".
      
      The problem is that the wrong symbol was defined as the default value
      for the choice.  Using the correct value gets rid of the infinite loop.
      
      Note:  if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input
      config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present
      in the generated config file.

      Pull integrity subsystem regression fix from James Morris:
       "Commit fdf90729 "ima: support new kernel module syscall" by error
        modified init_module() to return INTEGRITY_UNKNOWN (which is 4) to
        user space if the kernel was built with CONFIG_IMA_APPRAISE=y.
      
        As a result, user space can no longer load kernel modules using
        init_module().  This commit fixes this regression."

      Guo Chao authored
      If checksum fails, we should also release the buffer
      read from previous iteration.

      ext4: fix configuration dependencies for ext4 ACLs and security labels · 96465efe
      Valerie Aurora authored
      Commit "ext4: Remove CONFIG_EXT4_FS_XATTR" removed the configuration
      dependencies for ext4 xattrs from the ext4 ACLs and security labels
      configuration options, but did not replace them with a dependency on
      ext4 itself.  Add back the dependency on ext4 so the options only show
      up if ext4 is enabled.
