[ZLIB]: Fix external builds of zlib_inflate code.
[TG3]: Fix APE induced regression
[SKY2]: version 1.19
[SKY2]: use netdevice stats struct
[SKY2]: fiber advertise bits initialization (trivial)

Move zlib_inflate_blob() out into it's own source file,
infutil.c, so that things like the powerpc zImage builder
in arch/powerpc/boot/Makefile don't end up trying to
compile it.

Make sure and not dump reserved areas of device space.
Touching some of these causes machine check exceptions on boards
like D-Link DGE-550SX.
Coding note, used a complex switch statement rather than bitmap
because it is easier to relate the block values to the documentation
rather than looking at a encoded bitmask.

Currently find_legacy_serial_ports() can find no serial ports on the
OPB with flattened device tree. Thus no legacy boot console can be
initialized. Just the early udbg console works, which is initialized
with udbg_init_44x_as1 on the UART's physical address specified in
kernel config. This happens because we look for ns16750 serial
devices only and expect opb node to have a device type property. This
patch makes it look for ns16550-compatible devices and use
of_device_is_compatible() for opb in case device type is not
specified.

This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).
We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.
We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments. That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.
Parts of this patch were originally written by Ben Herrenschmidt.

All ppc32 systems except PReP and 8xx are capable of handling 3G of user
address space. Old legacy had set this to 2GB and no one has bothered to
fix it.
8xx could be bumped up to 3GB if its SW TLB miss handlers were fixed up
to properly determine kernel/user addresses.

asm-powerpc/mpc85xx.h was really a hold over from arch/ppc. Now that
more decoupling has occurred we can remove <asm/mpc85xx.h> and some of
its legacy.
As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h
for 85xx platforms. This is a stop gap until drivers stop using
CPM_MAP_ADDR.

The Lite5200 u-boot image doesn't entirely configure the processor
correctly and so Linux needs to fixup the cpu setup in setup_arch. Fixing
the CPU setup is good, but making it into common code is not a good idea.
New board ports should be encouraged not to take the lead of the lite5200
and instead get their firmware to setup the CPU the right way.

In testing the new clocksource and clockevent code on a PPC601
processor, I discovered that the clockevent multiplier value for the
decrementer clockevent was overflowing. Because the RTCL register in
the 601 effectively counts at 1GHz (it doesn't actually, but it
increases by 128 every 128ns), and the shift value was 32, that meant
the multiplier value had to be 2^32, which won't fit in an unsigned
long on 32-bit. The same problem would arise on any platform where
the timebase frequency was 1GHz or more (not that we actually have any
such machines today).
This fixes it by reducing the shift value to 16. Doing the
calculations with a resolution of 2^-16 nanoseconds (15 femtoseconds)
should be quite adequate. :)

On old powermacs, we sometimes set the decrementer to 1 in order to
trigger a decrementer interrupt, which we use to handle an interrupt
that was pending at the time when it was re-enabled. This was causing
the decrementer clock event device to call the event function for the
next event early, which was causing problems when high-res timers were
not enabled.
This fixes the problem by recording the timebase value at which the
next event should occur, and checking the current timebase against the
recorded value in timer_interrupt. If it isn't time for the next
event, it just reprograms the decrementer and returns.
This also subtracts 1 from the value stored into the decrementer,
which is appropriate because the decrementer interrupts on the
transition from 0 to -1, not when the decrementer reaches 0.
