      netpoll: revert 6bdb7fe3 and fix be_poll() instead · 072a9c48
      Amerigo Wang authored
      Against -net.
      
      In the patch "netpoll: re-enable irq in poll_napi()", I tried to
      fix the following warning:

      by reenabling IRQ before calling ->poll, but it seems more
      problems are introduced after that patch:
      
      http://ozlabs.org/~akpm/stuff/IMG_20120824_122054.jpg
      http://marc.info/?l=linux-netdev&m=134563282530588&w=2
      
      So it is safe to fix be2net driver code directly.
      
      This patch reverts the offending commit and fixes be_poll() by
      avoid disabling BH there, this is okay because be_poll()
      can be called either by poll_napi() which already disables
      IRQ, or by net_rx_action() which already disables BH.

      brcm80211: smac: set interface down on reset · ea2d2183
      Vladimir Zapolskiy authored
      This change marks interface as down on reset, otherwise the driver can't
      reinitialize itself properly.
      
      Without the change a transient problem turns out to be critical and leads
      to inavailability to reset the driver without brcmsmac module unload/load
      cycle:
      
          ieee80211 phy0: wl0: PSM microcode watchdog fired at 5993 (seconds). Resetting.
          brcms_c_dpc : PSM Watchdog, chipid 0xa8d9, chiprev 0x1
          ieee80211 phy0: wl0: fatal error, reinitializing
          ieee80211 phy0: Hardware restart was requested

      Trivial conflict in drivers/video/console/fbcon.c due to me having
      already applied the fbcon flashing cursor vs deinit race fix, and Dave

      Pull SCSI target fixes from Nicholas Bellinger:
       "The executive summary includes:
      
         - Post-merge review comments for tcm_vhost (MST + nab)
         - Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR)
         - Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou)
         - Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab)
         - Fix regression bug with handling of zero-length data CDBs (nab)
         - Fix vhost_scsi_target structure alignment (MST)
      
        Thanks again to everyone who contributed a bugfix patch, gave review
        feedback on tcm_vhost code, and/or reported a bug during their own
        testing over the last weeks.
      
        There is one other outstanding bug reported by Roland recently related
        to SCSI transfer length overflow handling, for which the current
        proposed bugfix has been left in queue pending further testing with
        other non iscsi-target based fabric drivers.
      
        As the patch is verified with loopback (local SGL memory from SCSI
        LLD) + tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric
        ports, it will be included into the next 3.6-rc-fixes PULL request."
