      m68knommu: fix dereference of port.tty · bc0c36d3
      由 Greg Ungerer 提交于 
      The struct_tty associated with a port is now a direct pointer
from within the local private driver info struct. So fix all uses
of it.

      spi/pxa2xx pci: fix the release - remove race · 0f3e1d27
      由 Sebastian Andrzej Siewior 提交于 
      Right now the platform device and its platform data is included in one big
struct which requires its custom ->release function. The problem with the
release function within the driver is that it might be called after the
driver was removed because someone was holding a reference to it and it
was not called right after platform_device_unregister(). So we also free
the platform device memory to which one might hold a reference.

This patch uses the normal pdev functions so this kind of race does not
occur.

      isdn: hisax: Use l2headersize() instead of dup (and buggy) func. · 6d90e8f4
      由 David S. Miller 提交于 
      There was a bug in my commit c978e7bb
("hisax: Fix unchecked alloc_skb() return.")

One of the l2->flag checks is wrong.

Even worse it turns out I'm duplicating an existing function,
so use that instead.

      sfc: Add TX queues for high-priority traffic · 94b274bf
      由 Ben Hutchings 提交于 
      Implement the ndo_setup_tc() operation with 2 traffic classes.

Current Solarstorm controllers do not implement TX queue priority, but
they do allow queues to be 'paced' with an enforced delay between
packets.  Paced and unpaced queues are scheduled in round-robin within
two separate hardware bins (paced queues with a large delay may be
placed into a third bin temporarily, but we won't use that).  If there
are queues in both bins, the TX scheduler will alternate between them.

If we make high-priority queues unpaced and best-effort queues paced,
and high-priority queues are mostly empty, a single high-priority queue
can then instantly take 50% of the packet rate regardless of how many
of the best-effort queues have descriptors outstanding.

We do not actually want an enforced delay between packets on best-
effort queues, so we set the pace value to a reserved value that
actually results in a delay of 0.

      sfc: Distinguish queue lookup from test for queue existence · 525da907
      由 Ben Hutchings 提交于 
      efx_channel_get_{rx,tx}_queue() currently return NULL if the channel
isn't used for traffic in that direction.  In most cases this is a
bug, but some callers rely on it as an existence test.

Add existence test functions efx_channel_has_{rx_queue,tx_queues}()
and use them as appropriate.

Change efx_channel_get_{rx,tx}_queue() to assert that the requested
queue exists.

Remove now-redundant initialisation from efx_set_channels().
