      fuse: fix attributes after open(O_TRUNC) · a0822c55
      Ken Sumrall authored
      The attribute cache for a file was not being cleared when a file is opened
      with O_TRUNC.
      
      If the filesystem's open operation truncates the file ("atomic_o_trunc"
      feature flag is set) then the kernel should invalidate the cached st_mtime
      and st_ctime attributes.
      
      Also i_size should be explicitly be set to zero as it is used sometimes
      without refreshing the cache.

      sgi-xpc: XPC fails to discover partitions with all nasids above 128 · c22c7aef
      Robin@sgi.com authored
      UV hardware defines 256 memory protection regions versus the baseline 64
      with increasing size for the SN2 ia64.  This was overlooked when XPC was
      modified to accomodate both UV and SN2.
      
      Without this patch, a user could reconfigure their existing system and
      suddenly disable cross-partition communications with no indication of what
      has gone wrong.  It also prevents larger configurations from using
      cross-partition communication.

      lock_page_cgroup and unlock_page_cgroup are implemented using
      bit_spinlock.  bit_spinlock doesn't touch the bit if we are on non-SMP
      machine, so we can't use the bit to check whether the lock was taken.
      
      Let's introduce is_page_cgroup_locked based on bit_spin_is_locked instead
      of PageCgroupLocked to fix it.

      nommu: yield CPU while disposing VM · 04c34961
      Steven J. Magnani authored
      Depending on processor speed, page size, and the amount of memory a
      process is allowed to amass, cleanup of a large VM may freeze the system
      for many seconds.  This can result in a watchdog timeout.
      
      Make sure other tasks receive some service when cleaning up large VMs.

      include/linux/fs.h: fix userspace build · 3a3a1af3
      Loïc Minier authored
      dpkg uses fiemap but didn't particularly need to include stdint.h so far.
      Since 367a51a3 ("fs: Add FITRIM ioctl"), build of linux/fs.h failed in
      dpkg with:
      
        In file included from ../../src/filesdb.c:27:0:
        /usr/include/linux/fs.h:37:2: error: expected specifier-qualifier-list before 'uint64_t'
      
      Use exportable type __u64 to avoid the dependency on stdint.h.
      
      b31d42a5 ("Fix compile brekage with !CONFIG_BLOCK") fixed only the
      kernel build by including linux/types.h, but this also fixed "make
      headers_check", so don't revert it.

      xen/events: Use PIRQ instead of GSI value when unmapping MSI/MSI-X irqs. · 12334715
      Konrad Rzeszutek Wilk authored
      When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the
      vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we
      need to provide the PIRQ and the vector value. What we did instead
      was to provide the GSI (which was zero) and the vector value, and we
      got these unhappy error messages:
      
      (XEN) irq.c:1575: dom0: pirq 0 not mapped
      [    7.733415] unmap irq failed -22
      
      This patches fixes this and we use the PIRQ value instead of the GSI
      value.

      The issue is that we don't set IO permissions for the Linux kernel early enough.
      
      The call sequence used to be:
      
          xen_start_kernel()
      	x86_init.oem.arch_setup = xen_setup_arch;
              setup_arch:
                 - early_cpu_init
                     - early_init_amd
                        - read_pci_config
                 - x86_init.oem.arch_setup [ xen_arch_setup ]
                     - set IO permissions.
      
      We need to set the IO permissions earlier on, which this patch does.

      of/phylib: Use device tree properties to initialize Marvell PHYs. · cf41a51d
      David Daney authored
      Some aspects of PHY initialization are board dependent, things like
      indicator LED connections and some clocking modes cannot be determined
      by probing.  The dev_flags element of struct phy_device can be used to
      control these things if an appropriate value can be passed from the
      Ethernet driver.  We run into problems however if the PHY connections
      are specified by the device tree.  There is no way for the Ethernet
      driver to know what flags it should pass.
      
      If we are using the device tree, the struct phy_device will be
      populated with the device tree node corresponding to the PHY, and we
      can extract extra configuration information from there.
      
      The next question is what should the format of that information be?
      It is highly device specific, and the device tree representation
      should not be tied to any arbitrary kernel defined constants.  A
      straight forward representation is just to specify the exact bits that
      should be set using the "marvell,reg-init" property:
      
            phy5: ethernet-phy@5 {
              reg = <5>;
              compatible = "marvell,88e1149r";
              marvell,reg-init =
                      /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */
                      <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */
                      /* mix %:0, led[0123]:drive low off hiZ */
                      <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */
                      /* default blink periods. */
                      <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */
                      /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */
                      <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */
            };
      
            phy6: ethernet-phy@6 {
              reg = <6>;
              compatible = "marvell,88e1118";
              marvell,reg-init =
                      /* Fix rx and tx clock transition timing */
                      <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */
                      /* Adjust LED drive. */
                      <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */
                      /* irq, blink-activity, blink-link */
                      <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */
            };
      
      The Marvell PHYs have a page select register at register 22 (0x16), we
      can specify any register by its page and register number.  These are
      the first and second word.  The third word contains a mask to be ANDed
      with the existing register value, and the fourth word is ORed with the
      result to yield the new register value.  The new marvell_of_reg_init
      function leaves the page select register unchanged, so a call to it
      can be dropped into the .config_init functions without unduly
      affecting the state of the PHY.
      
      If CONFIG_OF_MDIO is not set, there is no of_node, or no
      "marvell,reg-init" property, the PHY initialization is unchanged.

      qlge: Fix incorrect usage of module parameters and netdev msg level · 84cf7029
      Sonny Rao authored
      Driver appears to be mistaking the permission field with default value
      in the case of debug and qlge_irq_type.
      
      Driver is also passing debug as a bitmask into netif_msg_init()
      which wants a number of bits.  Ron Mercer suggests we should
      change this to pass in -1 so the defaults get used instead,
      which makes the default much less verbose.

      ALSA: azt3328: period bug fix (for PA), add missing ACK on stop timer · 78ac07b0
      Andreas Mohr authored
      . Fix PulseAudio "ALSA driver bug" issue
        (if we have two alternated areas within a 64k DMA buffer, then max
        period size should obviously be 32k only).
        Back references:
         http://pulseaudio.org/wiki/AlsaIssues
         http://fedoraproject.org/wiki/Features/GlitchFreeAudio
      . In stop timer function, need to supply ACK in the timer control byte.
      . Minor log output correction
      
      When I did my first PA testing recently, the period size bug resulted
      in quite precisely observeable half-period-based playback distortion.
      
      PA-based operation is quite a bit more underrun-prone (despite its
      zero-copy optimizations etc.) than raw ALSA with this rather spartan
      sound hardware implementation on my puny Athlon.
      
      Note that even with this patch, azt3328 still doesn't work for both
      cases yet, PA tsched=0 and tsched
      (on tsched=0 it will playback tiny fragments of periods, leading to tiny
      stuttering sounds with some pauses in between, whereas with
      timer-scheduled operation playback works fine - minus some quite increased
      underrun trouble on PA vs. ALSA, that is).
