The fs_no mean used to be fs_enet driver driven, hence it was an
enumeration across all the possible fs_enet "users" in the SoC. Now, with
QE on the pipeline, and to make DTS descriptions more clear, fs_no features
relevant SoC part number, with additional field to describe the SoC type.
Another reason for that is now not only fs_enet is going to utilize those
stuff. There might be UART, HLDC, and even USB, so to prevent confusion and
be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were
updated in that concern, as well as the relevant DTS.

Incorporating the new way of cpm2 immr access, introduced in the previous
patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and
powerpc approved working( real actions taken in powerpc only, ppc just
has a wrapper to keep init stuff consistent).

The stuff below cleans up the code attempting to remap the whole cpm2_immr
early, as well as places happily assuming that fact. This is more like the 2.4
legacy stuff, and is at least confusing and unclear now.
To keep the world comfortable, a new mechanism is introduced: before accessing
specific immr register/register set, one needs to map it, using cpm2_map(<reg>),
for instance, access to CPM command register will look like
volatile cpm_cpm2_t *cp = cpm2_map(im_cpm);
keeping the code clear, yet without "already defined somewhere" cpm2_immr.
So far, unmapping code is not implemented, but it's not a big deal to add it,
if the whole idea makes sense.

This makes the 8560 evaluation board fully supported under arch/powerpc,
as the first board with CPM2 SoC peripherals. The brand new devicetree
nodes are introduced (intending to be a subset of the QuiccEngine-equipped
models, with dts sources placed into the kernel according to the new convention.
Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART
update), the both TSEC eth ,FCC Eths, and both SCC UARTs are
working. The relevant drivers are still capable to drive users in ppc,
which was verified with 8272ADS (SCC uart+FCC eth).
This is also verified on mpc8540 and actually make it work (PCI stuff
working as well)

This patch contains necessary modifications to support the CPM2 SoC peripherals.
For the time being, those are fs_enet Ethernet driver and cpm_uart serial.
Written initially to support mpc8560, it also suites to the part of the large PQ2
(more specifically, mpc8260) family.

Add support for new hardware and bumps the version to 3.6.10. It seems
there were several changes introduced including soft_irq. I decided to
bump the major number to reflect these changes. Since we're still
supporting older vendor kernels I need some way differentiate between
kernel versions <=2.6.10 and newer kernels >=2.6.16.

MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, which
doesn't exist in userspace. Move an #endif /* __KERNEL__ */ down a few lines
to prevent that.
Also, remove the broken definition of PAGE_SIZE which is never going to be
correct -- in the absence of PAGE_SIZE, non-broken userspace will fall back to
using sysconf() or getpagesize() instead.

Some files which don't exist in userspace were being included unconditionally
in asm-i386/elf.h. Move the offending #includes down a few lines so that
they're protected by #ifdef __KERNEL__
In fact, we probably want to kill off all userspace use of asm/elf.h -- but we
aren't there yet, so we should at least make it possible to include it for
now.

There's useful stuff in <linux/timex.h> but <asm/timex.h> has nothing for
userspace. Stop exporting it, and include it only from within the existing
#ifdef __KERNEL__ part of <linux/timex.h>
This fixes a 'make headers_check' failure on i386 because asm-i386/timex.h
includes both asm-i386/tsc.h and asm-i386/processor.h, neither of which are
exported to userspace. It's not entirely clear _why_ it includes either of
these, but it does.

We don't need any of this crap included from the user-visible part of nfs_fs.h
-- remove it all.
In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is
there any need for anything else? And magic numbers should probably move to
<linux/magic.h> rather than being strewn across various fs-specific include
files which exist in userspace for solely that purpose.
With this patch, 'make header_check' works again at least on PowerPC.
