      fs/affs: fix casting in printed messages · 08fe100d

        - "inode.i_ino" is "unsigned long",
        - "loff_t" is always "unsigned long long",
        - "sector_t" should be cast to "unsigned long long" for printing,
        - "u32" should not be cast to "unsigned int" for printing.

      eventfd: don't take the spinlock in eventfd_poll · e22553e2
      Chris Mason authored
      
      
      The spinlock in eventfd_poll is trying to protect the count of events so
      it can decide if it should return POLLIN, POLLERR, or POLLOUT.  But,
      because of the way we drop the lock after calling poll_wait, and drop it
      again before returning, we have the same pile of races with the lock as
      we do with a single read of ctx->count().
      
      This replaces the lock with a read barrier and single read.
      
      eventfd_write does a single bump of ctx->count, so this should not add
      new races with adding events.  eventfd_read is similar, it will do a
      single decrement with the lock held, and so we're making the race with
      concurrent readers slightly larger.
      
      This spinlock is the top CPU user in kernel code during one of our
      workloads.  Removing it gives us a ~2% boost.

      vmcore: fix PT_NOTE n_namesz, n_descsz overflow issue · 34b47764
      WANG Chao authored
      
      
      When updating PT_NOTE header size (ie.  p_memsz), an overflow issue
      happens with the following bogus note entry:
      
        n_namesz = 0xFFFFFFFF
        n_descsz = 0x0
        n_type   = 0x0
      
      This kind of note entry should be dropped during updating p_memsz.  But
      because n_namesz is 32bit, after (n_namesz + 3) & (~3), it's overflow to
      0x0, the note entry size looks sane and reserved.
      
      When userspace (eg.  crash utility) is trying to access such bogus note,
      it could lead to an unexpected behavior (eg.  crash utility segment fault
      because it's reading bogus address).
      
      The source of bogus note hasn't been identified yet.  At least we could
      drop the bogus note so user space wouldn't be surprised.

      kexec: add IND_FLAGS macro · b28c2ee8
      Geoff Levand authored
      
      
      Add a new kexec preprocessor macro IND_FLAGS, which is the bitwise OR of
      all the possible kexec IND_ kimage_entry indirection flags.  Having this
      macro allows for simplified code in the prosessing of the kexec
      kimage_entry items.  Also, remove the local powerpc definition and use the
      generic one.

      kexec: add bit definitions for kimage entry flags · cf2df639
      Geoff Levand authored
      
      
      Define new kexec preprocessor macros IND_*_BIT that define the bit
      position of the kimage entry flags.  Change the existing IND_* flag macros
      to be defined as bit shifts of the corresponding IND_*_BIT macros.  Also
      wrap all C language code in kexec.h with #if !defined(__ASSEMBLY__) so
      assembly files can include kexec.h to get the IND_* and IND_*_BIT macros.
      
      Some CPU instruction sets have tests for bit position which are convenient
      in implementing routines that operate on the kimage entry list.  The
      addition of these bit position macros in a common location will avoid
      duplicate definitions and the chance that changes to the IND_* flags will
      not be propagated to assembly files.

      kexec: simplify conditional · 518a0c71
      Geoff Levand authored
      
      
      Simplify the code around one of the conditionals in the kexec_load syscall
      routine.
      
      The original code was confusing with a redundant check on KEXEC_ON_CRASH
      and comments outside of the conditional block.  This change switches the
      order of the conditional check, and cleans up the comments for the
      conditional.  There is no functional change to the code.

      kexec: remove never used member destination in kimage · 73d7e3ea
      Baoquan He authored
      
      
      struct kimage has a member destination which is used to store the real
      destination address of each page when load segment from user space buffer
      to kernel.  But we never retrieve the value stored in kimage->destination,
      so this member variable in kimage and its assignment operation are
      redundent code.
      
      I guess for_each_kimage_entry just does the work that kimage->destination
      is expected to do.
      
      So in this patch just make a cleanup to remove it.

      Pull ARM SoC DT updates from Olof Johansson:
       "DT changes continue to be the bulk of our merge window contents.
      
        We continue to have a large set of changes across the board as new
        platforms and drivers are added.
      
        Some of the new platforms are:
         - Alphascale ASM9260
         - Marvell Armada 388
         - CSR Atlas7
         - TI Davinci DM816x
         - Hisilicon HiP01
         - ST STiH418
      
        There have also been some sweeping changes, including relicensing of
        DTS contents from GPL to GPLv2+/X11 so that the same files can be
        reused in other non-GPL projects more easily.  There's also been
        changes to the DT Makefile to make it a little less conflict-ridden
        and churny down the road"

      Pull ARM SoC platform changes from Olof Johansson:
       "New and updated SoC support.  Also included are some cleanups where
        the platform maintainers hadn't separated cleanups from new developent
        in separate branches.
      
        Some of the larger things worth pointing out:
      
         - A large set of changes from Alexandre Belloni and Nicolas Ferre
           preparing at91 platforms for multiplatform and cleaning up quite a
           bit in the process.
      
         - Removal of CSR's "Marco" SoC platform that never made it out to the
           market.  We love seeing these since it means the vendor published
           support before product was out, which is exactly what we want!
      
        New platforms this release are:
      
         - Conexant Digicolor (CX92755 SoC)
         - Hisilicon HiP01 SoC
         - CSR/sirf Atlas7 SoC
         - ST STiH418 SoC
         - Common code changes for Nvidia Tegra132 (64-bit SoC)
      
        We're seeing more and more platforms having a harder time labelling
        changes as cleanups vs new development -- which is a good sign that
        we've come quite far on the cleanup effort.  So over time we might
        start combining the cleanup and new-development branches more"
