A few improvements to the Freescale/ColdFire FEC driver:
. some formatting cleanups
. add support for the FEC device in the ColdFire 523x processor family
. add support for MAC address setting on MOD5272 and M5272C3 boards
. don't re-read the PHY status register many times
. ack status interrupt before reading status register
. move printing init message to after full init (so that the
ethX name is filled out for printing)

The bulk of the change. Use per cpu MCA/INIT stacks. Change the SAL
to OS state (sos) to be per process. Do all the assembler work on the
MCA/INIT stacks, leaving the original stack alone. Pass per cpu state
data to the C handlers for MCA and INIT, which also means changing the
mca_drv interfaces slightly. Lots of verification on whether the
original stack is usable before converting it to a sleeping process.

Reading the INIT record from SAL during the INIT event has proved to be
unreliable, and a source of hangs during INIT processing. The new
MCA/INIT handlers remove the need to get the INIT record from SAL.
Change salinfo.c so mca.c can just flag that a new record is available,
without having to read the record during INIT processing. This patch
can be applied without the new MCA/INIT handlers.
Also clean up some usage of NR_CPUS which should have been using
cpu_online().

When introducing the generic asm-offsets.h support the dependency
chain for the prepare targets was changed. All build scripts expecting
include/asm/asm-offsets.h to be made when using the prepare target would broke.
With the limited number of prepare targets left in arch Makefiles
the trivial solution was to introduce a new arch specific target: archprepare
The dependency chain looks like this now:
prepare
|
+--> prepare0
|
+--> archprepare
|
+--> scripts_basic
+--> prepare1
|
+---> prepare2
|
+--> prepare3
So prepare 3 is processed before prepare2 etc.
This guaantees that the asm symlink, version.h, scripts_basic
are all updated before archprepare is processed.
prepare0 which build the asm-offsets.h file will need the
actions performed by archprepare.
The head target is now named prepare, because users scripts will most
likely use that target, but prepare-all has been kept for compatibility.

The UML fault handler was recently changed to enforce PROT_NONE protections,
by requiring VM_READ or VM_EXEC on VMA's.
However, by mistake, things were changed such that VM_READ is always checked,
also on write faults; so a VMA mapped with only PROT_WRITE is not readable
(unless it's prefaulted with MAP_POPULATE or with a write), which is different
from i386.
Discovered while testing remap_file_pages protection support.

Turns out that, for UML, a *lot* of VM-related trivial functions are not
inlined but rather normal functions.
In other sections of UML code, this is justified by having files which
interact with the host and cannot therefore include kernel headers, but in
this case there's no such justification.
I've had to turn many of them to macros because of missing declarations. While
doing this, I've decided to reuse some already existing macros.

Inside the linker script, insert the code for DWARF debug info sections. This
may help GDB'ing a Uml binary. Actually, it seems that ld is able to guess
what I added correctly, but normal linker scripts include this section so it
should be correct anyway adding it.
On request by Sam Ravnborg <sam@ravnborg.org>, I've added it to
asm-generic/vmlinux.lds.s. I've also moved there the stabs debug section,
used the new macro in i386 linker script and added DWARF debug section to
that.
In the truth, I've not been able to verify the difference in GDB behaviour
after this change (I've seen large improvements with another patch). This
may depend on my binutils version, older one may have worse defaults.
However, this section is present in normal linker script, so add it at
least for the sake of cleanness.
