      KVM: Fix buffer overflow in kvm_set_irq() · f2ebd422
      Avi Kivity authored
      kvm_set_irq() has an internal buffer of three irq routing entries, allowing
      connecting a GSI to three IRQ chips or on MSI.  However setup_routing_entry()
      does not properly enforce this, allowing three irqchip routes followed by
      an MSI route to overflow the buffer.
      
      Fix by ensuring that an MSI entry is added to an empty list.

      vfs: move inode stat information closer together · 2f9d3df8
      Linus Torvalds authored
      The comment above it says "Stat data, not accessed from path walking",
      but in fact some of inode fields we use for the common stat data was way
      down at the end of the inode, causing unnecessary cache misses for the
      common stat operations.
      
      The inode structure is pretty big, and this can change padding depending
      on field width, but at least on the common 64-bit configurations this
      doesn't change the size.  Some of our inode layout has historically been
      to tro to avoid unnecessary padding fields, but cache locality is at
      least as important for layout, if not more.
      
      Noticed by looking at kernel profiles, and noticing that the "i_blkbits"
      access stood out like a sore thumb.

      Pull arm fixes for ux500 mismerge mishap from Arnd Bergmann:
       "The device tree conversion for arm/ux500 in 3.5 turns out to be
        incomplete because of a mismerge done by Linus Walleij that I failed
        to notice early enough and that Lee Jones as the original author of
        those patches did not manage to fix during the -next cycle.  While we
        originally to get a much larger set of ux500 device tree enablement
        patches merged, this did not happen in time.
      
        After some discussion at Linaro Connect conference this week, Lee has
        been able to do damage control and provide a series to put the broken
        platform back into usable shape for both DT and non-DT based booting.
      
        This series has not been part of linux-next and is based on top of the
        current state of the upstream kernel rather than an -rc, but this is
        the best we could manage given the earlier breakage."
