      ARM: footbridge: remove RTC_IRQ definition · ec8e8208
      Arnd Bergmann authored
      Since commit bd8abc9a "ARM: mc146818rtc: remove unnecessary include of
      mach/irqs.h", building footbridge_defconfig results in this warning:
      
      In file included from include/linux/mc146818rtc.h:16:0,
                       from arch/arm/mach-footbridge/isa-rtc.c:21:
      arch/arm/include/asm/mc146818rtc.h:10:0: warning: "RTC_IRQ" redefined [enabled by default]
      arch/arm/mach-footbridge/include/mach/irqs.h:93:0: note: this is the location of the previous definition
      
      The above commit was intentionally made to catch errors like this,
      where code relies on the RTC_IRQ definition. The only driver using
      it is the legacy PC-style drivers/char/rtc.c driver.
      However, the ARM architecture has been using the RTC_LIB framework
      since at least 2006, and that doesn't use it.

      ARM: ks8695: __arch_virt_to_dma type handling · 113f7ae5

      __arch_virt_to_dma expects a virtual address pointer, but

      Arnd Bergmann authored
      The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and
      mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c
      file, but it includes both headers, a safe workaround should be
      to just undefine it from the .c file. This is a bit hacky and
      the headers should be fixed to not both define it, but for now
      it gets us around an annoying warning.

      vfs: dcache: fix deadlock in tree traversal · 8110e16d
      Miklos Szeredi authored
      IBM reported a deadlock in select_parent().  This was found to be caused
      by taking rename_lock when already locked when restarting the tree
      traversal.
      
      There are two cases when the traversal needs to be restarted:
      
       1) concurrent d_move(); this can only happen when not already locked,
          since taking rename_lock protects against concurrent d_move().
      
       2) racing with final d_put() on child just at the moment of ascending
          to parent; rename_lock doesn't protect against this rare race, so it
          can happen when already locked.
      
      Because of case 2, we need to be able to handle restarting the traversal
      when rename_lock is already held.  This patch fixes all three callers of
      try_to_ascend().
      
      IBM reported that the deadlock is gone with this patch.
      
      [ I rewrote the patch to be smaller and just do the "goto again" if the
        lock was already held, but credit goes to Miklos for the real work.

       "Here are two USB bugfixes for your 3.6-rc7 tree.
      
        The OHCI fix has been reported a number of times and is a regression
        from 3.5, and the patch that causes the regression was on the way to
        the -stable trees before I was reminded (again) that this fix needed
        to get to your tree soon.
      
        The host controller bugfix was reported in older kernels as being
        pretty easy to trigger, and has been tested by Red Hat and their
        customers.
      
        Both have been in the usb-next branch in the -next tree for a while
        now, I just cherry-picked them out to get to you in time for the 3.6
        release.

      inetpeer: fix token initialization · bc9259a8
      Nicolas Dichtel authored
      When jiffies wraps around (for example, 5 minutes after the boot, see
      INITIAL_JIFFIES) and peer has just been created, now - peer->rate_last can be
      < XRLIM_BURST_FACTOR * timeout, so token is not set to the maximum value, thus
      some icmp packets can be unexpectedly dropped.
      
      Fix this case by initializing last_rate to 60 seconds in the past.

      qlcnic: Fix scheduling while atomic bug · 68b3f28c
      Narendra K authored
      In the device close path, 'qlcnic_fw_destroy_ctx' and
      'qlcnic_poll_rsp' call msleep. But  'qlcnic_fw_destroy_ctx' and
      'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock
      held resulting in scheduling while atomic bug causing the following
      trace.
      
      I observed that the commit 012dc19a
      from John Fastabend addresses a similar issue in ixgbevf driver.
      Adopting the same approach used in the commit, this patch uses mdelay
      to address the issue.
