This fixes yet another sunsab problem, when console is set to anything
but the first port. The console framework calls sunsab_console_setup
for each port, and we end up setting up a console on a not yet
discovered port, which leads to an Oops. Instead, defer console setup
until the requested port is properly initialized. Tested on an E250
through an RSC console.

The "%uhi" needs to be "%%uhi" because we want a real
"%" character in the assembler here, instead of an
assembler variable expansion.

Aparently older GCCs were more liberal and interpreted
this %-letter as a literal "%" for whatever reason.

This small change allows for easy per-route workarounds for broken hosts or
middleboxes that are not compliant with TCP standards for window scaling.
Rather than having to turn off window scaling globally. This patch allows
reducing or disabling window scaling if window clamp is present.

sctp_make_abort_user() now takes the msg_len along with the msg
so that we don't have to recalculate the bytes in iovec.
It also uses memcpy_fromiovec() so that we don't go beyond the
length allocated.

It is good to have this fix even if verify_iovec() is fixed to
return error on overflow.

I know nothing about io scheduler, but I suspect set_task_ioprio() is not safe.

current_io_context() initializes "struct io_context", then sets ->io_context.
set_task_ioprio() running on another cpu may see the changes out of order, so
->set_ioprio(ioc) may use io_context which was not initialized properly.

Patch from Ben Dooks

A number of small issues with the S3C24XX DMA have
cropped up, which this patch fixes. These are:

  - check wether we can load another buff in start
  - update state handling in s3c2410_dma_lastxfer
  - only reload in irq if channel is not idle
  - more informative timeout errors (add source)
  - do not call request_irq() with irqs locked
  - added waitforstop function

The patch also adds a S3C2410_DMAOP_STARTED for
the occasions when the driver wants to ensure that
the DMA system load state is resynced after loading.

When the bridge recomputes features, it does not maintain the
constraint that SG/GSO must be off if TX checksum is off.
This patch adds that constraint.

On a completely unrelated note, I've also added TSO6 and TSO_ECN
feature bits if GSO is enabled on the underlying device through
the new NETIF_F_GSO_SOFTWARE macro.
