Get rid of the mdelay call in rhine_disable_linkmon. The function
is called from the via-rhine versions of mdio_read and mdio_write.
Those functions are indirectly called from rhine_check_media and
rhine_tx_timeout, both of which can be called in interrupt context.
So, create tx_timeout_task and check_media_task as instances of struct
work_struct inside of rhine_private. Then, change rhine_tx_timeout to
invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task),
moving the work to process context. Also, change rhine_error (invoked
from rhine_interrupt) to invoke schedule_work for check_media_task
(i.e. rhine_check_media_task), which simply calls rhine_check media
in process context. Finally, add a call to flush_scheduled_work in
rhine_close to avoid any resource conflicts with pending work items.

We keep IB device structures around until the last sysfs reference is
gone, but we shouldn't ask the low-level driver to do anything after
the LLD unregisters the device. To handle this, check the reg_state
field and just fail sysfs show() requests if the device has already
been unregistered.

From Suzanne Wood <suzannew@cs.pdx.edu>:
Clarify RCU implementation in bpqether.c.
Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls
list_del_rcu(), substitute list_for_each_entry_rcu() for
list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start().
Add rcu dereference protection in bpq_seq_next().
The rcu_read_lock()/unlock() in bpq_device_event() are removed because
netdev event handlers are called with RTNL locking in place.
FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires
synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which
cannot block. Herbert Xu notes that synchronization is done here by
unregister_netdevice(). This calls synchronize_net() which in turn uses
synchronize_rcu().

This patch fixes the following bugs with offline diagnostics
code(run with "ethtool -t").
1. After running offline diagnostics, adapter would report
corrupted packets on receive. This was because of adapter not
being brought out of "RLDRAM test mode".
2. Current EEPROM test works only for Xframe I. Since Xframe II
uses different interface(SPI), support for this interface has
been added. Also, since SPI supports write access to all areas
of EEPROM, negative testing is done only for Xframe I.
3. Return values from subfunctions of offline diagnostics have
been corrected.
4. In register test, expected value from rx_queue_cfg register
is made to depend on adapter type.
5. After the test, need to restore values at EEPROM offsets
0x4F0 and 0x7F0. These locations were modified as part of test.
6. Use macro SPECIAL_REG_WRITE for write access to mc_rldram_test_ctrl
register. Also, couple of unnecessary writes to mc_rldram_test_ctrl
have been removed.

"...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which
I'm using the Vesa FB driver. When the machine has been idle for some
time and the driver attempts to powerdown the display, rather than the
display going blank, it goes gray with several strange lines. When I
hit the "shift" key or other-wise wake up the display, the old video
state is not fully restored..."
vesafb recently added a blank method which has only 2 states, powerup and
powerdown. The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.
