FSVOtest in this case, since I don't have the hardware...
However, all changes seen by gcc are actually
- explicit cast to unsigned short in return expression of functions
returning unsigned short
- csum_fold() return type changed from unsigned int to __sum16
(unsigned short), same as for all other architecture and as net/* expects;
expression actually returned is ((~(sum << 16)) >> 16) with sum being
unsigned 32bit, so it's (a) going to fit into the range of unsigned short
and (b) had been unsigned all along, so no sign expansion mess happened.

When transferring to IRQ5 from an exception, save SYSCFG in memory across the
transfer and clear the trace bit.
When we get a single step exception, check whether we can safely clear the
trace bit in SYSCFG. We can (and should) clear it after the first instruction
of the interrupt handler; the first insn saves SYSCFG to the stack in all
handlers.

This replaces the duplicated arch-specific versions of "sys_pipe()" with
one unified implementation. This removes almost 250 lines of duplicated
code.
It's marked __weak, so that *if* an architecture wants to override the
default implementation it can do so by simply having its own replacement
version, since many architectures use alternate calling conventions for
the 'pipe()' system call for legacy reasons (ie traditional UNIX
implementations often return the two file descriptors in registers)
I still haven't changed the cris version even though Linus says the BKL
isn't needed. The arch maintainer can easily do it if there are really
no obstacles.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

Remove the circular buffering mechanism for exceptions. Instead, point RETX
at a safe location from which to fetch three NOPs.
This safe location is now in the fixed code area, and also used for certain
anomaly workarounds, to ensure that user space can find a valid ICPLB when
things are built with CONFIG_MPU.
Also, save I/DCPLB_FAULT_ADDRESS when lowering to level 5, since the hardware
reg is valid only at exception level.

The irq setup code no longer calls gpio request and free.
This patch also changes the default gpio_free behavior on Blackfin.
A freed GPIO keeps it's last state, and is not defaulted back to
an input. This is also what all other architectures do.
