      Ath5k: fix dma operation · e86600c7
      Jiri Slaby authored
      Don't sync
      - coherent mapping (descriptors)
      - before unmap, it's useless
      - (wrongly anyway -- for_cpu) beacon skb, it's just mapped,
        so by the device yet

      Ath5k: flush work · 274c7c36
      Jiri Slaby authored
      Make sure that the irq is not in progress after stop. This means
      two things:
      - ensure the intr setting register is set by flushing posted values
      - call synchronize_irq() after that
      
      Also flush stop tx write, inform callers of the tx stop about still
      pending transfers (unsuccessful stop) and finally don't wait another
      3ms in ath5k_rx_stop, since ath5k_hw_stop_rx_dma ensures transfer to
      be finished.
      
      Make sure all writes will be ordered in respect to locks by mmiowb().

      Ath5k: kill tasklets on shutdown · 10488f8a
      Jiri Slaby authored
      Don't forget to kill tasklets on stop to not panic if they
      fire after freeing some structures.

      Ath5k: fix memory corruption · 3a0f2c87
      Jiri Slaby authored
      When signal is noisy, hardware can use all RX buffers and since the last
      entry in the list is self-linked, it overwrites the entry until we link
      new buffers.
      
      Ensure that we don't free this last one until we are 100% sure that it
      is not used by the hardware anymore to not cause memory curruption as
      can be seen below.
      
      This is done by checking next buffer in the list. Even after that we
      know that the hardware refetched the new link and proceeded further
      (the next buffer is ready) we can finally free the overwritten buffer.
      
      We discard it since the status in its descriptor is overwritten (OR-ed
      by new status) too.

      Trond Myklebust authored
      In order to avoid the "Busy inodes after unmount" error message, we need to
      ensure that nfs_async_unlink_release() releases the super block after the
      call to nfs_free_unlinkdata().

      The new super.c:nfs_remount function doesn't check the validity of the

      The obvious patch seems to check the pointers, and not to do anything if
      the happend to be NULL.

      [SCSI] extend the last_sector_bug flag to cover more sectors · 2b142900
      Alan Jenkins authored
      The last_sector_bug flag was added to work around a bug in certain usb
      cardreaders, where they would crash if a multiple sector read included the
      last sector. The original implementation avoids this by e.g. splitting an 8
      sector read which includes the last sector into a 7 sector read, and a single
      sector read for the last sector.  The flag is enabled for all USB devices.
      
      This revealed a second bug in other usb cardreaders, which crash when they
      get a multiple sector read which stops 1 sector short of the last sector.
      Affected hardware includes the Kingston "MobileLite" external USB cardreader
      and the internal USB cardreader on the Asus EeePC.
      
      Extend the last_sector_bug workaround to ensure that any access which touches
      the last 8 hardware sectors of the device is a single sector long.  Requests
      are shrunk as necessary to meet this constraint.
      
      This gives us a safety margin against potential unknown or future bugs
      affecting multi-sector access to the end of the device.  The two known bugs
      only affect the last 2 sectors.  However, they suggest that these devices
      are prone to fencepost errors and that multi-sector access to the end of the
      device is not well tested.  Popular OS's use multi-sector accesses, but they
      rarely read the last few sectors.  Linux (with udev & vol_id) automatically
      reads sectors from the end of the device on insertion.  It is assumed that
      single sector accesses are more thoroughly tested during development.

      Minor cleanups for the MMC/SD support on avr32:
      
       - Make at32_add_device_mci() properly initialize "missing"

       - Switch over to gpio_is_valid() instead of testing for only
         one designated value.
      
       - Provide STK1002 platform data for the unlikely case that
         switches are set so first Ethernet controller isn't in use.
         (That's the only way to get card detect and writeprotect
         switch sensing on the STK1000.)
      
      And get rid of one "unused variable" warning.

      KVM: s390: Fix possible host kernel bug on lctl(g) handling · 5a00a5e7
      Christian Borntraeger authored
      The lctl(g) instructions require a specific alignment for the parameters.
      The architecture requires a specification program check if these alignments
      are not used. Enforcing this alignment also removes a possible host BUG,
      since the get_guest functions check for proper alignment and emits a BUG.
