ARM: allow alignment fault mode to be configured at kernel boot

their gconv code, which if not fixed up, results in segfaults during
boot.  This can prevent systems booting properly.

There is no clear hard-configurable default for this; the desired
default depends on the nature of the userspace which is going to be
booted.

vgaarb: fix "target=default" passing

Commit 77c1ff3982c6b36961725dd19e872a1c07df7f3b fixed the userspace
pointer dereference, but introduced another bug pointed out by Eugene Teo
in RH bug #564264. Instead of comparing the point we were at in the string,
we instead compared the beginning of the string to "default".

[SCSI] fcoe: Only rmmod fcoe.ko if there are no active connections

Currently we're gracefully tearing down each active connection
when fcoe.ko is removed. We shouldn't allow the user to destroy
connections by removing the module. We should force the user to
destroy each connection and then the module can be removed.

This patch makes it so a refrerence count on the module is taken
each time a fcoe_interface is created. The reference count
is dropped when the fcoe_interface is destroyed. This makes it
so that module_exit() doesn't get called unless all fcoe_interfaces
have been destroyed.

This patch leaves the removal of interfaces in the module_exit
routine so that if the user does a 'rmmod -f' we'll clean everything
up before removing the module.

The module_put line was put before the out_putdev goto line because
we should only be decrementing the reference count if a
fcoe_interface is actually destroyed. If we can't find the netdev
or the fcoe_interface then it's assumed that something else has
destroyed the fcoe_interface and it would have decremented the
reference count at that time.

serial: 8250: add serial transmitter fully empty test

When controlling an industrial radio modem it can be necessary to
manipulate the handshake lines in order to control the radio modem's
transmitter, from userspace.

The transmitter should not be turned off before all characters have been
transmitted.  serial8250_tx_empty() was reporting that all characters were
transmitted before they actually were.

===

Discovered in parallel with more testing and analysis by Kees Schoenmakers
as follows:

I ran into an NetMos 9835 serial pci board which behaves a little
different than the standard.  This type of expansion board is very common.

"Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together
with the "UART_LSR_THRE" bit when writing data to the device.

The NetMos device does it slightly different

I believe that the TEMT bit is coupled to the shift register.  The problem
is that after writing data to the device and very quickly after that one
does call serial8250_tx_empty, it returns the wrong information.

My patch makes the test more robust (and solves the problem) and it does
not affect the already correct devices.

Alan:

  We may yet need to quirk this but now we know which chips we have a
  way to do that should we find this breaks some other 8250 clone with
  dodgy THRE.

USB: r8a66597-udc: Prototype IS_ERR() and PTR_ERR()

The build of r8a66597-udc was failing on ARM since IS_ERR() and
PTR_ERR() weren't protyped.  Presumably err.h is being pulled in by
another header on other platforms.

USB: usbfs: properly clean up the as structure on error paths

I notice that the processcompl_compat() function seems to be leaking the
'struct async *as' in the error paths.

I think that the calling convention is fundamentally buggered. The
caller is the one that did the "reap_as()" to get the as thing, the
caller should be the one to free it too.

Freeing it in the caller also means that it very clearly always gets
freed, and avoids the need for any "free in the error case too".
