      Pull ARM SoC fixes from Arnd Bergmann:
       "This comes a bit later than I planned, and as a consequence is a
        larger than it should be.
      
        Most of the changes are devicetree fixes, across lots of platforms:
        Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic
        Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
      
        Also across many platforms, I applied an older series of simple
        randconfig build fixes. This includes making the CONFIG_MTD_XIP option
        compile again, which had been broken for many years and probably has
        not been missed, but it felt wrong to just remove it completely.
      
        The only other changes are:
      
         - We enable HWSPINLOCK in defconfig to get some Qualcomm boards to
           work out of the box.
      
         - A few regression fixes for Texas Instruments OMAP2+.
      
         - A boot regression fix for the Renesas regulator quirk.
      
         - A suspend/resume fix for Uniphier SoCs, fixing the resume of the
           system bus"

      sparc64: Fix exception handling in UltraSPARC-III memcpy. · 0ede1c40
      David S. Miller 提交于
      Mikael Pettersson reported that some test programs in the strace-4.18
      testsuite cause an OOPS.
      
      After some debugging it turns out that garbage values are returned
      when an exception occurs, causing the fixup memset() to be run with
      bogus arguments.
      
      The problem is that two of the exception handler stubs write the
      successfully copied length into the wrong register.

      (1) insert a SD card and mount it
      (2) hotplug it, so it will leave md->usage still be counted
      (3) reboot the system which will sync data and umount the card

      When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
      set, DIR1 is expected to have SGID bit set (and owning group equal to
      the owning group of 'DIR0').  However when 'DIR0' also has some default
      ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
      'DIR1' to get cleared if user is not member of the owning group.
      
      Fix the problem by moving posix_acl_update_mode() out of ocfs2_set_acl()
      into ocfs2_iop_set_acl().  That way the function will not be called when
      inheriting ACLs which is what we want as it prevents SGID bit clearing
      and the mode has been properly set by posix_acl_create() anyway.  Also
      posix_acl_chmod() that is calling ocfs2_set_acl() takes care of updating
      mode itself.

      mm: allow page_cache_get_speculative in interrupt context · 1ee1c3f5
      Kan Liang 提交于
      Kernel panic when calling the IRQ-safe __get_user_pages_fast in NMI
      handler.
      
      The bug was introduced by commit 2947ba05 ("x86/mm/gup: Switch GUP
      to the generic get_user_page_fast() implementation").
      
      The original x86 __get_user_page_fast used plain get_page() or
      page_ref_add().  However, the generic __get_user_page_fast uses
      page_cache_get_speculative(), which has VM_BUG_ON(in_interrupt()).
      
      There is no reason to prevent page_cache_get_speculative from using in
      interrupt context.  According to the author, putting a BUG_ON there is
      just because the code is not verifying correctness of interrupt races.
      I did some tests in interrupt context.  There is no issue found.
      
      Removing VM_BUG_ON(in_interrupt()) for page_cache_get_speculative().

      ipc: add missing container_of()s for randstruct · ade9f91b
      Kees Cook 提交于
      When building with the randstruct gcc plugin, the layout of the IPC
      structs will be randomized, which requires any sub-structure accesses to
      use container_of().  The proc display handlers were missing the needed
      container_of()s since the iterator is passing in the top-level struct
      kern_ipc_perm.
      
      This would lead to crashes when running the "lsipc" program after the
      system had IPC registered (e.g. after starting up Gnome):
      
        general protection fault: 0000 [#1] PREEMPT SMP
