The current smc91x I/O routines ifdef the solution engine subtypes
individually, which is rather bogus, as they can simply use
CONFIG_SOLUTION_ENGINE instead. This fixes it for some of the other
solution engines that weren't included in the ifdef list (SH7206
specifically).

There are also inb/outb definitions which are totally bogus (missing
brackets in _both_ cases, SMC_CAN_USE_8BIT == 0, and even better, they
try to use a 16-bit access to fake 8-bit access). Kill that nonsense off
completely.

To assure the symmetry of poll enable/disable in up/down, we should
initialize the netdevice to be poll_disabled at load time. Doing
this after register_netdevice leaves us open to another race, so
lets move all the netif_* calls above register_netdevice so the
stack starts out how we expect it to be.

The interface for network device VLAN extension was confusing.
The kill_vid function is only really useful for devices that do
hardware filtering. Devices that only do VLAN receiption without
filtering were being forced to provide the hook, and there were
bugs in those devices.

Many drivers had kill_vid routine that called vlan_group_set_device, with
NULL, but that is done already.

In the bootwrapper code for powerpc, we include HOSTCFLAGS into the
BOOTCFLAGS used for building the zImage wrapper code.  Since the
wrapper code is not host code, this makes no sense.  This patch
removes the use of HOSTCFLAGS here, instead including directly into
BOOTCFLAGS those flags from the normal kernel CFLAGS which also make
sense in the bootwrapper code.

In particular, this makes the bootwrapper use -msoft-float, preventing
the compiler from generating floating point instructions.  Previously,
under some circumstances the compiler could generate floating point
instructions in the bootwrapper which would cause exceptions on
embedded CPUS which don't have floating point support.

I think we have a subtle race on ppc64 with the tlb batching.  The
common code expects tlb_flush() to actually flush any pending TLB
batch.  It does that because it delays all page freeing until after
tlb_flush() is called, in order to ensure no stale reference to
those pages exist in any TLB, thus causing potential access to
the freed pages.

However, our tlb_flush only triggers the RCU for freeing page
table pages, it does not currently trigger a flush of a pending
TLB/hash batch, which is, I think, an error.  This fixes it.

The recent addition of assembler flags for 44x.c and ebony.c in the
bootwrapper to make them compile on certain toolchains was not correct
and could break other platforms.  This patch switches to using a
compiler flag instead, which implies the appropriate assembler flag,
and also stops the compiler itself generating instructions which are
invalid for the platform in question.

for at least a -proper- 32/64 bits split and possibly more cleanups
