bluetooth : __rfcomm_dlc_close lock fix

Lockdep warning will be trigged while rfcomm connection closing.

The locks taken in rfcomm_dev_add:
rfcomm_dev_lock --> d->lock

In __rfcomm_dlc_close:
d->lock --> rfcomm_dev_lock (in rfcomm_dev_state_change)

There's two way to fix it, one is in rfcomm_dev_add we first locking
d->lock then the rfcomm_dev_lock

The other (in this patch), remove the locking of d->lock for
rfcomm_dev_state_change because just locking "d->state = BT_CLOSED;"
is enough.

bluetooth : use lockdep sub-classes for diffrent bluetooth protocol

'rfcomm connect' will trigger lockdep warnings which is caused by
locking diffrent kinds of bluetooth sockets at the same time.

So using sub-classes per AF_BLUETOOTH sub-type for lockdep.

Thanks for the hints from dave jones.

mac80211: sta_info_flush() fixes

When the IBSS code tries to flush the STA list, it does so in
an atomic context. Flushing isn't safe there, however, and
requires the RTNL, so we need to defer it to a workqueue.

mac80211: clean up sta_info_destroy() users wrt. RCU/locking

Calling sta_info_destroy() doesn't require RCU-synchronisation

require rtnl-locking so insert that where necessary.

Also clean up the code doing it internally to be a bit clearer and

drivers/net/tokenring/3c359.c: use time_* macros

The functions time_before, time_before_eq, time_after, and time_after_eq are
more robust for comparing jiffies against other values.

So use the time_after() macro, defined in linux/jiffies.h, which deals with
wrapping correctly.

3c509: convert to isa_driver and pnp_driver

Convert 3c509 driver to isa_driver and pnp_driver.  The result is that
autoloading using udev and hibernation works with ISA PnP cards.  It also adds
hibernation support for non-PnP ISA cards.

xcvr module parameter was removed as its value was not used.

Tested using 3 ISA cards in various combinations of PnP and non-PnP modes.
EISA and MCA only compile-tested.

usb net: asix does not really need 10/100mbit

The asix usb driver currently depends on NET_ETHERNET which means you
cannot enable this driver if you only have 1000mbit enabled in your kernel.
Since there is no real dependency between the NET_ETHERNET portion and the

drivers/net/pasemi_mac.c is enabled by CONFIG_PASEMI_MAC, which depends on
PPC64 && PCI. However pasemi_mac.c uses several routines that are only

[netdrvr] tulip_read_eeprom fixes for BUG 4420

If "location" is > "addr_len" bits, the high bits of location would interfere
with the READ_CMD sent to the eeprom controller.

A patch was submitted to bug:
    http://bugzilla.kernel.org/show_bug.cgi?id=4420

which simply truncated the "location", read whatever was in "location
modulo addr_len", and returned that value. That avoids confusing the
eeprom but seems like the wrong solution to me.

Correct would be to not read beyond "1 << addr_len" address of the eeprom.
I am submitting two changes to implement this:
1) tulip_read_eeprom will return zero (since we can't return -EINVAL)
   if this is attempted (defensive programming).
2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't
   iterate past addr_len bits and make sure the entire tp->eeprom[]
   array is cleared.

I konw we don't strictly need both. I would prefer both in the tree
since it documents the issue and provides a second "defense" from
the bug from creeping back in.
