24d4502632 m68knommu: simplify the ColdFire 5307 GPIO struct setup
The GPIO data struct setup is now the only remaining code in the platform
gpio.c file. So move it to the platform config.c code and remove the gpio.c
file.

c269d4efaa m68knommu: introduce macros to simplify ColdFire GPIO table initialization
We have very large tables in the ColdFire CPU GPIO setup code that essentially
boil down to 2 distinct types of GPIO pin initiaization. Using 2 macros we can
reduce these large tables to at most a dozen lines of setup code, and in quite
a few cases a single table entry.

Introduce these 2 macros into the existing mcfgpio.h header.

0c22fafd31 m68k: merge the MMU and non-MMU signal.c code
The MMU (signal_mm.c) and non-MMU (signal_no.c) versions of the m68k
architecture signal handling code are very similar. Most of their code is
the same.

Merge the two back into a single signal.c, and move some of the code around
inside the file to minimize the number of #ifdefs required. Specificially
we can group out the CONFIG_FPU and the CONFIG_MMU code. We end up needing
a few other "#ifdef CONFIG_MMU" as well, but not too many.

Move tcp_try_coalesce() protocol independent part to
skb_try_coalesce().

skb_try_coalesce() can be used in IPv4 defrag and IPv6 reassembly,
to build optimized skbs (less sk_buff, and possibly less 'headers')

skb_try_coalesce() is zero copy, unless the copy can fit in destination
header (its a rare case)

kfree_skb_partial() is also moved to net/core/skbuff.c and exported,
because IPv6 will need it in patch (ipv6: use skb coalescing in
reassembly).

Pull x86 linker bug workarounds from Peter Anvin.

GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly
turns certain relocation entries absolute.  Section-relative symbols
that are part of otherwise empty sections are silently changed them to
absolute.  We rely on section-relative symbols staying section-relative,
and actually have several sections in the linker script solely for this
purpose.

See for example

   http://sourceware.org/bugzilla/show_bug.cgi?id=14052

We could just black-list the buggy linker, but it appears that it got
shipped in at least F17, and possibly other distros too, so it's sadly
not some rare unusual case.

This backports the workaround from the x86/trampoline branch, and as
Peter says: "This is not a minimal fix, not at all, but it is a tested
code base."
