      arch: remove unused *_segments() macros/functions · c17c0204
      Tobias Klauser authored
      Some architectures define the no-op macros/functions copy_segments,
      release_segments and forget_segments. These are used nowhere in the
      tree, so removed them.

       "It turns out our single-fix pull from last week was too good to be
        true. I missed a few fixes in that pull that had already come in
        because I was on leave, but also we hadn't found the bugs yet. So this
        week it's a bit bigger, though not ridiculous. Hopefully things will
        settle down from here on.
      
        Four fixes for the new instruction emulation code. A fix for CPU
        offline on bare metal machines when certain idle states are not
        supported, and a fix for a device_node refcounting oops during CPU
        hotplug, caused by recent changes.
      
        Going to stable are a fix for an oops during core dump on machines
        that have TM (Transactional Memory) disabled. Reordering some EEH
        initialisation to avoid trashing memory, and another device_node
        refcounting fix.
      
        And a few other minor things.

      The function pcibios_scanbus() references
      the function __init pcibios_map_irq().
      This is often because pcibios_scanbus lacks a __init

      MIPS: Fix input modify in __write_64bit_c0_split() · c22c8043
      James Hogan authored
      The inline asm in __write_64bit_c0_split() modifies the 64-bit input
      operand by shifting the high register left by 32, and constructing the
      full 64-bit value in the low register (even on a 32-bit kernel), so if
      that value is used again it could cause breakage as GCC would assume the
      registers haven't changed when they have.
      
      To quote the GCC extended asm documentation:
      > Warning: Do not modify the contents of input-only operands (except for
      > inputs tied to outputs). The compiler assumes that on exit from the
      > asm statement these operands contain the same values as they had
      > before executing the statement.
      
      Avoid modifying the input by using a temporary variable as an output
      which is modified instead of the input and not otherwise used. The asm
      is always __volatile__ so GCC shouldn't optimise it out. The low
      register of the temporary output is written before the high register of
      the input is read, so we have two constraint alternatives, one where
      both use the same registers (for when the input value isn't subsequently
      used), and one with an early clobber on the output in case the low
      output uses the same register as the high input. This allows the
      resulting assembly to remain mostly unchanged.
      
      A diff of a MIPS32r6 kernel reveals only three differences, two in
      relation to write_c0_r10k_diag() in cpu_probe() (register allocation
      rearranged slightly but otherwise identical), and one in relation to
      write_c0_cvmmemctl2() in kvm_vz_local_flush_guesttlb_all(), but the
      octeon CPU is only supported on 64-bit kernels where
      __write_64bit_c0_split() isn't used so that shouldn't matter in
      practice. So there currently doesn't appear to be anything broken by
      this bug.

      powerpc/pseries: Fix parent_dn reference leak in add_dt_node() · b537ca6f
      Tyrel Datwyler authored
      A reference to the parent device node is held by add_dt_node() for the
      node to be added. If the call to dlpar_configure_connector() fails
      add_dt_node() returns ENOENT and that reference is not freed.
      
      Add a call to of_node_put(parent_dn) prior to bailing out after a
      failed dlpar_configure_connector() call.

      powerpc/pseries: Fix "OF: ERROR: Bad of_node_put() on /cpus" during DLPAR · 087ff6a5
      Tyrel Datwyler authored
      Commit 215ee763 ("powerpc: pseries: remove dlpar_attach_node
      dependency on full path") reworked dlpar_attach_node() to no longer
      look up the parent node "/cpus", but instead to have the parent node
      passed by the caller in the function parameter list.
      
      As a result dlpar_attach_node() is no longer responsible for freeing
      the reference to the parent node. However, commit 215ee763 failed
      to remove the of_node_put(parent) call in dlpar_attach_node(), or to
      take into account that the reference to the parent in the caller
      dlpar_cpu_add() needs to be held until after dlpar_attach_node()
      returns.
      
      As a result doing repeated cpu add/remove dlpar operations will
      eventually result in the following error:
      
        OF: ERROR: Bad of_node_put() on /cpus

      Fix the issue by removing the of_node_put(parent) call from
      dlpar_attach_node(), and ensuring that the reference to the parent
      node is properly held and released by the caller dlpar_cpu_add().

      Otherwise we end up not yet having computed the right diag data size
      on powernv where EEH initialization is delayed, thus causing memory
      corruption later on when calling OPAL.

      ipc/shm: Fix order of parameters when calling copy_compat_shmid_to_user · 58aff0af
      Will Deacon authored
      Commit 553f770e ("ipc: move compat shmctl to native") moved the
      compat IPC syscall handling into ipc/shm.c and refactored the struct
      accessors in the process. Unfortunately, the call to
      copy_compat_shmid_to_user when handling a compat {IPC,SHM}_STAT command
      gets the arguments the wrong way round, passing a kernel stack address
      as the user buffer (destination) and the user buffer as the kernel stack
      address (source).
      
      This patch fixes the parameter ordering so the buffers are accessed
      correctly.

      iov_iter: fix page_copy_sane for compound pages · a90bcb86
      Petar Penkov authored
      Issue is that if the data crosses a page boundary inside a compound
      page, this check will incorrectly trigger a WARN_ON.
      
      To fix this, compute the order using the head of the compound page and
      adjust the offset to be relative to that head.
      
      Fixes: 72e809ed ("iov_iter: sanity checks for copy to/from page
      primitives")
