      A fix from Jesper Juhl removes an assignment in an ASSERT when a compare
      is intended.  Two fixes from Mitsuo Hayasaka address off-by-ones in XFS
      quota enforcement.

      xhci: Fix encoding for HS bulk/control NAK rate. · 340a3504
      Sarah Sharp authored
      The xHCI 0.96 spec says that HS bulk and control endpoint NAK rate must
      be encoded as an exponent of two number of microframes.  The endpoint
      descriptor has the NAK rate encoded in number of microframes.  We were
      just copying the value from the endpoint descriptor into the endpoint
      context interval field, which was not correct.  This lead to the VIA
      host rejecting the add of a bulk OUT endpoint from any USB 2.0 mass
      storage device.
      The fix is to use the correct encoding.  Refactor the code to convert
      number of frames to an exponential number of microframes, and make sure
      we convert the number of microframes in HS bulk and control endpoints to
      an exponent.
      This should be back ported to kernels as old as 2.6.31, that contain the
      commit dfa49c4a "USB: xhci - fix math
      in xhci_get_endpoint_interval"

      USB: Set hub depth after USB3 hub reset · a45aa3b3
      Elric Fu authored
      The superspeed device attached to a USB 3.0 hub(such as VIA's)
      doesn't respond the address device command after resume. The
      root cause is the superspeed hub will miss the Hub Depth value
      that is used as an offset into the route string to locate the
      bits it uses to determine the downstream port number after
      reset, and all packets can't be routed to the device attached
      to the superspeed hub.
      Hub driver sends a Set Hub Depth request to the superspeed hub
      except for USB 3.0 root hub when the hub is initialized and
      doesn't send the request again after reset due to the resume
      process. So moving the code that sends the Set Hub Depth request
      to the superspeed hub from hub_configure() to hub_activate()
      is to cover those situations include initialization and reset.
      The patch should be backported to kernels as old as 2.6.39.

      USB: Fix handoff when BIOS disables host PCI device. · cab928ee
      Sarah Sharp authored
      On some systems with an Intel Panther Point xHCI host controller, the
      BIOS disables the xHCI PCI device during boot, and switches the xHCI
      ports over to EHCI.  This allows the BIOS to access USB devices without
      having xHCI support.
      The downside is that the xHCI BIOS handoff mechanism will fail because
      memory mapped I/O is not enabled for the disabled PCI device.
      Jesse Barnes says this is expected behavior.  The PCI core will enable
      BARs before quirks run, but it will leave it in an undefined state, and
      it may not have memory mapped I/O enabled.
      Make the generic USB quirk handler call pci_enable_device() to re-enable
      MMIO, and call pci_disable_device() once the host-specific BIOS handoff
      is finished.  This will balance the ref counts in the PCI core.  When
      the PCI probe function is called, usb_hcd_pci_probe() will call
      pci_enable_device() again.
      This should be back ported to kernels as old as 2.6.31.  That was the
      first kernel with xHCI support, and no one has complained about BIOS
      handoffs failing due to memory mapped I/O being disabled on other hosts
      (EHCI, UHCI, or OHCI).

      (They both provided patches to fix it)
      This patch also (at the request of the list) fixes the fact that
      ARM has both LE and BE versions however the audit code was called as if
      it was always BE.  If audit userspace were to try to interpret the bits
      it got from a LE system it would obviously do so incorrectly.  Fix this
      by using the right arch flag on the right system.

      xfs: make inode quota check more general · c922bbc8
      Mitsuo Hayasaka authored
      The xfs checks quota when reserving disk blocks and inodes. In the block
      reservation, it checks if the total number of blocks including current
      usage and new reservation exceed quota. In the inode reservation,
      it checks using the total number of inodes including only current usage
      without new reservation. However, this inode quota check works well
      since the caller of xfs_trans_dquot() always sets the argument of the
      number of new inode reservation to 1 or 0 and inode is reserved one by
      one in current xfs.
      To make it more general, this patch changes it to the same way as the
      block quota check.

      xfs: change available ranges of softlimit and hardlimit in quota check · 20f12d8a
      Mitsuo Hayasaka authored
      In general, quota allows us to use disk blocks and inodes up to each
      limit, that is, they are available if they don't exceed their limitations.
      Current xfs sets their available ranges to lower than them except disk
      inode quota check. So, this patch changes the ranges to not beyond them.

      ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency' · e23e8c06
      Myron Stowe authored
      The patch series to re-factor PCI's 'latency timer' setup (re:
      http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
      remove the ARM specific definition of 'pcibios_max_latency' once such
      had been moved into the pci core resulting in ARM related compile
      errors -
        drivers/built-in.o:(.data+0x230): multiple definition of
        arch/arm/common/built-in.o:(.data+0x40c): first defined here
        make[1]: *** [vmlinux.o] Error 1
      In the series, patch 2/16 (commit 168c8619) converted the ARM
      specific version of 'pcibios_set_master()' to a non-inlined version.
      This was done in preperation for hosting it up into PCI's core, which
      was done in patch 10/16 (commit 96c55900) of the series (and
      where the removal of ARM's 'pcibios_max_latency' was overlooked).

      ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised · 910ba598
      Santosh Shilimkar authored
      Current ARM local timer code registers CPUFREQ notifiers even in case
      the twd_timer_setup() isn't called. That seems to be wrong and
      would eventually lead to kernel crash on the CPU frequency transitions
      on the SOCs where the local timer doesn't exist or broken because of
      hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt).
      The issue was observed with v3.3-rc3 and building an OMAP2+ kernel
      on OMAP3 SOC which doesn't have TWD.
      Below is the dump for reference :

      Bitten by my dislike for modules on the machines I use, and the fact
      that apparently nobody else actually wanted to test the patches I sent
      Snif. Nobody else cares.
      Anyway, we probably should uninline the 'kernel_fpu_begin()' function
      that is what modules actually use and that references this, but this is
      the minimal fix for now.
