      ARM: omap: resolve nebulous 'Error setting wl12xx data' · 70d669de
      Russell King 提交于
      It's useful to print the error code when a called function fails so a
      diagnosis of why it failed is possible.  In this case, it fails because
      we try to register some data for the wl12xx driver, but as the driver
      is not configured, a stub function is used which simply returns -ENOSYS.
      
      Let's do the simple thing for -rc and print the error code.
      
      Also, the return code from platform_register_device() at each of these
      sites was not being checked.  Add some checking, and again print the
      error code.
      
      This should be fixed properly for the next merge window so we don't
      issue error messages merely because a driver is not configured.

      ARM: omap: fix wrapped error messages in omap_hwmod.c · 4f8a428d
      Russell King 提交于
      While trying to debug my OMAP platforms, they emitted this message:
      
      omap_hwmod: %s: enabled state can only be entered from initialized, idle, or disabled state
      
      The following backtrace said it was from a function called '_enable',
      which didn't provide much clue.  Grepping didn't find it either.
      
      The message is wrapped, so unwrap the message so grep can find it.  Do
      the same for three other messages in this file.

      ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup() · a98f77bb

      This is often because sdp3430_twl_gpio_setup lacks a __init
      annotation or the annotation of omap2_hsmmc_init is wrong.
      
      sdp3430_twl_gpio_setup() is called via platform data from the
      gpio-twl4030 module, which can be inserted and removed at runtime.
      This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents
      it being marked with an __init annotation.
      
      As it calls omap2_hsmmc_init() unconditionally, the only resolution to
      this warning is to remove the __init markings from omap2_hsmmc_init()
      and its called functions.  This addresses the functions in hsmmc.c.

      ARM: omap: preemptively fix section mismatch in omap4_sdp4430_wifi_mux_init() · d5de63f5
      Russell King 提交于
      Found by review.
      
      omap4_sdp4430_wifi_mux_init() is called by an __init marked function,
      and only calls omap_mux_init_gpio() and omap_mux_init_signal() which
      are both also an __init marked functions.
      
      The only reason this doesn't issue a warning is because the compiler
      inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init().
      
      So, lets add the __init annotation to ensure this remains safe should
      the compiler choose not to inline.

      On my OMAP4 platform, I'm getting this error message repeated several
      times at boot:
      
      omap_vc_i2c_init: I2C config for all channels must match.
      omap_vc_i2c_init: I2C config for all channels must match.
      
      This doesn't help identify what the problem is.  Fix this message to
      be more informative:
      
      omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0).
      omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0).
      
      This allows us to identify which voltage domains have a problem, and
      what the I2C configuration state (a boolean, i2c_high_speed) setting
      being used actually is.
      
      From this we find that omap4_core_pmic has i2c_high_speed false, but
      omap4_iva_pmic and omap4_mpu_pmic both have it set true.

        But I'm very confident that it's "just" a missing expire on exit, so

        the slopes.
      
        - Killing the barrier part of mtip32xx.  It doesn't really support
          barriers, and it doesn't need them (writes are fully ordered).
      
        - A few fixes from Dan Carpenter, preventing overflows of integer
          multiplication.
      
        - A fixup for loop, fixing a previous commit that didn't quite solve
          the partial read problem from Dave Young.
      
        - A bio integer overflow fix from Kent Overstreet.
      
        - Improvement/fix of the door "keep locked" part of the cdrom shared
          code from Paolo Benzini.
      
        - A few cfq fixes from Shaohua Li.
      
        - A fix for bsg sysfs warning when removing a file it did not create
          from Stanislaw Gruszka.
      
        - Two fixes for floppy from Vivek, preventing a crash.
      
        - A few block core fixes from Tejun.  One killing the over-optimized
          ioc exit path, cleaning that up nicely.  Two others fixing an oops
          on elevator switch, due to calling into the scheduler merge check

      block: fix lockdep warning on io_context release put_io_context() · d8c66c5d
      Tejun Heo 提交于
      11a3122f "block: strip out locking optimization in put_io_context()"
      removed ioc_lock depth lockdep annoation along with locking
      optimization; however, while recursing from put_io_context() is no
      longer possible, ioc_release_fn() may still end up putting the last
      reference of another ioc through elevator, which wlil grab ioc->lock
      triggering spurious (as the ioc is always different one) A-A deadlock
      warning.
      
      As this can only happen one time from ioc_release_fn(), using non-zero
      subclass from ioc_release_fn() is enough.  Use subclass 1.

      1) GRO MAC header comparisons were ethernet specific, breaking other
         link types.  This required a multi-faceted fix to cure the originally
         noted case (Infiniband), because IPoIB was lying about it's actual
         hard header length.  Thanks to Eric Dumazet, Roland Dreier, and
         others.
      
      2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.
         From Anisse Astier.
      
      3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.
      
      4) ipv4 TCP reset generation needs to respect any network interface
         binding from the socket, otherwise route lookups might give a
         different result than all the other segments received.  From Shawn
         Lu.
      
      5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas
         Graf.
      
      6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.
      
      7) Revert skge PCI mapping changes that are causing crashes for some
         folks, from Stephen Hemminger.
      
      8) IPV4 route lookups fill in the wildcarded fields of the given flow
         lookup key passed in, which is fine most of the time as this is
         exactly what the caller's want.  However there are a few cases that
         want to retain the original flow key values afterwards, so handle
         those cases properly.  Fix from Julian Anastasov.
      
      9) IGB/IXGBE VF lookup bug fixes from Greg Rose.
      
      10) Properly null terminate filename passed to ethtool flash device
          method, from Ben Hutchings.
      
      11) S3 resume fix in via-velocity from David Lv.

          Tarnyagin.

      net: Don't proxy arp respond if iif == rt->dst.dev if private VLAN is disabled · 70620c46
      Thomas Graf 提交于
      Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed
      the behavior of arp proxy to send arp replies back out on the interface
      the request came in even if the private VLAN feature is disabled.
      
      Previously we checked rt->dst.dev != skb->dev for in scenarios, when
      proxy arp is enabled on for the netdevice and also when individual proxy
      neighbour entries have been added.
      
      This patch adds the check back for the pneigh_lookup() scenario.

      the nexthop of SRR in ip_option->nexthop and update iph->daddr until
      we get to ip_forward_options(), but we need to update it before
      ip_rt_get_source(), otherwise we may get a wrong src.

      When the netprio_cgroup module is not loaded, net_prio_subsys_id
      is -1, and so sock_update_prioidx() accesses cgroup_subsys array
      with negative index subsys[-1].

      Neil Horman 提交于
      So we delay the allocation till the priority is set through cgroup,
      and this makes skb_update_priority() faster when it's not set.
      
      This also eliminates an off-by-one bug similar with the one fixed
      in the previous patch.

      xfs: use a normal shrinker for the dquot freelist · 04da0c81
      Christoph Hellwig 提交于
      Stop reusing dquots from the freelist when allocating new ones directly, and
      implement a shrinker that actually follows the specifications for the
      interface.  The shrinker implementation is still highly suboptimal at this
      point, but we can gradually work on it.
      
      This also fixes an bug in the previous lock ordering, where we would take
      the hash and dqlist locks inside of the freelist lock against the normal
      lock ordering.  This is only solvable by introducing the dispose list,
      and thus not when using direct reclaim of unused dquots for new allocations.
      
      As a side-effect the quota upper bound and used to free ratio values in
      /proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the
      new world order.
