David Vrabel 4656d5de95 wusb: reset WUSB devices with SetAddress(0)
Using a Reset Device IE to reset a WUSB device is too heavyweight as it
causes the devcie to disconnect (which the USB stack does not expect and
cannot handle).  Instead, do a SetAddress(0); SetAddress(AuthAddr) for
authenticated devices.

Unauthenticated devices will not be reset and the stack will have to rely
on the device timing out after TrustTimeout and disconnecting.

David Vrabel 1cde7f68ce uwb: order IEs by element ID
ECMA-368 requires that IEs in a beacon must be sorted by element ID.  Most
hardware uses the ordering in the Set IE URC command so get the ordering
right on the host.

Also refactor the IE management code:
  - use uwb_ie_next() instead of uwb_ie_for_each().
  - remove unnecessary functions.
  - API is now only uwb_rc_ie_add() and uwb_rc_ie_rm().

David Vrabel cae1c11414 uwb: reference count reservations
Reference counting the struct uwb_rsv's is safer and easier to get right than
the transferring ownership of the structures from the PAL to reservation
manager.

This fixes an oops in the debug PAL after a reservation timed out.

Geert Uytterhoeven d1a35e4d74 m68k: Disable Amiga serial console support if modular
If CONFIG_AMIGA_BUILTIN_SERIAL=m, I get the following warnings:

| drivers/char/amiserial.c: At top level:
| drivers/char/amiserial.c:2138: warning: data definition has no type or storage class
| drivers/char/amiserial.c:2138: warning: type defaults to 'int' in declaration of 'console_initcall'
| drivers/char/amiserial.c:2138: warning: parameter names (without types) in function declaration
| drivers/char/amiserial.c:2134: warning: 'amiserial_console_init' defined but not used

because console_initcall() is not defined (nor really sensible) in the
modular case.

So disable serial console support if the driver is modular.

Davide Libenzi 9ce209d64d epoll: avoid double-inserts in case of EFAULT
In commit f337b9c583 ("epoll: drop
unnecessary test") Thomas found that there is an unnecessary (always
true) test in ep_send_events().  The callback never inserts into
->rdllink while the send loop is performed, and also does the
~EP_PRIVATE_BITS test.  Given we're holding the mutex during this time,
the conditions tested inside the loop are always true.

HOWEVER.

The test "!ep_is_linked(&epi->rdllink)" wasn't there because we insert
into ->rdllink, but because the send-events loop might terminate before
the whole list is scanned (-EFAULT).

In such cases, when the loop terminates early, and when a (leftover)
file received an event while we're performing the lockless loop, we need
such test to avoid to double insert the epoll items.  The list_splice()
done a few steps below, will correctly re-insert the ones that were left
on "txlist".

This should fix the kenrel.org bugzilla entry 11831.

Arjan van de Ven 4d36a9e65d select: deal with math overflow from borderline valid userland data
Some userland apps seem to pass in a "0" for the seconds, and several
seconds worth of usecs to select().  The old kernels accepted this just
fine, so the new kernels must too.

However, due to the upscaling of the microseconds to nanoseconds we had
some cases where we got math overflow, and depending on the GCC version
(due to inlining decisions) that actually resulted in an -EINVAL return.

This patch fixes this by adding the excess microseconds to the seconds
field.

Also with thanks to Marcin Slusarz for spotting some implementation bugs
in the diagnostics patches.

Arjan van de Ven 44a504c405 wireless: fix regression caused by regulatory config option
The default for the regulatory compatibility option is wrong;
if you picked the default you ended up with a non-functional wifi
system (at least I did on Fedora 9 with iwl4965).
I don't think even the October 2008 releases of the various distros
has the new userland so clearly the default is wrong, and also
we can't just go about deleting this in 2.6.29...

Change the default to "y" and also adjust the config text a little to
reflect this.

This patch fixes regression #11859

With thanks to Johannes Berg for the diagnostics

Francois Romieu e383d56487 r8169: revert "read MAC address from EEPROM on init"
This reverts commit 7bf6bf4803.

The code has both a short existence and an increasing track of failures
despite some work to amend it for -rc1.  It is not just a matter of
reading the eeprom: sometimes the eeprom is read correctly, then the mac
address is not written correctly back into the mac registers.

Some chipsets seem to work reliably but it is not clear at this point if
the code can simply be made to work on a per-chipset basis and post -rc1
is not the place where I want to experiment these things.
