Setting these at create_context time or start_iso time doesn't matter
much, but raw1394 sets them at start_iso time so that will be easier to
emulate this way.

The dualbuffer DMA setup did not account for the iso trailer word
and thus didn't work correctly. With this fixed we can drop the
dual buffer fallback mode.

This patch fixes the poll routine for the natsemi driver so that if the
driver detects an RX state machine lockup then no interrupts will be
lost while the driver recovers from that.

The interrupt status register for the natsemi chips is clear on read and
was read unconditionally from both the interrupt and from the NAPI poll
routine, meaning that if the interrupt service routine was called (for
example, due to a shared interrupt) while a NAPI poll was scheduled
interrupts could be missed. This patch fixes that by ensuring that the
interrupt status register is only read by the interrupt handler when
interrupts are enabled from the chip.
It also reverts a workaround for this problem from the netpoll hook and
improves the trace for interrupt events.
Thanks to Sergei Shtylyov <sshtylyov@ru.mvista.com> for spotting the
issue, Mark Huth <mhuth@mvista.com> for a simpler method and Simon
Blake <simon@citylink.co.nz> for testing resources.

The natsemi drivers include functions for enabling and disabling
interrupts from the chip but these are not used in all code paths. This
patch changes the code paths that touch the interrupt enable register to
use the functions. In all cases this adds an extra PCI read to post the
operation but since none of these are in fast paths this shouldn't be
too much of a problem.

When bonding does fail over it calls set_mac_address. When this happens
as the result of another port going down, the phy_mutex that is common to
both ports is held, so it deadlocks. Setting the address doesn't need to do
anything that needs the phy_mutex, it already has the RTNL to protect against
other admin actions.
This change just disables the receiver to avoid any hardware confusion
while address is changing.

ocfs2_dlm: Add missing locks in dlm_empty_lockres

NB: driver is choke-full of code that will break on big-endian; as long
as the hardware is onboard-only we can live with that, but sooner or
later that'll need fixing.
