      net/fec: clean suspend/resume · 87cad5c3
      由 Eric Benard 提交于 
      Commit 59d4289b converted fec to dev_pm_ops but
didn't update the suspend/resume functions thus leading to the following warning :
"initialization from incompatible pointer type" when CONFIG_PM is set.

This patch also fixe a few indentation and style around CONFIG_PM area.

      net/fec: fix pm to survive to suspend/resume · e3fe8558
      由 Eric Bénard 提交于 
      * in the actual driver, calling fec_stop and fec_enet_init doesn't
allow to have a working network interface at resume (where a
ifconfig down and up is required to recover the interface)
* by using fec_enet_close and fec_enet_open, this patch solves this
problem and handle the case where the link changed between suspend
and resume
* this patch also disable clock at suspend and reenable it at resume

      net: convert multicast list to list_head · 22bedad3
      由 Jiri Pirko 提交于 
      Converts the list and the core manipulating with it to be the same as uc_list.

+uses two functions for adding/removing mc address (normal and "global"
 variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
 manipulation with lists on a sandbox (used in bonding and 80211 drivers)

      fec: don't enable irqs in hard irq context · 81538e74
      由 Uwe Kleine-König 提交于 
      fec_enet_mii, fec_enet_rx and fec_enet_tx are both only called by
fec_enet_interrupt in interrupt context.  So they must not use
spin_lock_irq/spin_unlock_irq.

This fixes:

      fec: fix recursive locking of mii_lock · 84177a20
      由 Uwe Kleine-König 提交于 
      mii_discover_phy is only called by fec_enet_mii (via mip->mii_func).  So
&fep->mii_lock is already held and mii_discover_phy must not call
mii_queue which locks &fep->mii_lock, too.

This was noticed by lockdep:

      fec: fix FEC driver packet transmission breakage · 9555b31e
      由 Greg Ungerer 提交于 
      Commit f0b3fbea ("FEC Buffer rework")
breaks transmission of packets where the skb data buffer is not memory
aligned according to FEC_ALIGNMENT. It incorrectly passes to
dma_sync_single() the buffer address directly from the skb, instead of
the address calculated for use (which may be the skb address or one of
the bounce buffers).

It seems there is no use converting the cpu address of the buffer to
a physical either, since dma_map_single() expects the cpu address and
will return the dma address to use in the descriptor. So remove the use
of __pa() on the buffer address as well.

This patch is against 2.6.30-rc5. This breakage is a regression over
2.6.30, which does not have this problem.
