This fixes up the kernel for gcc4. The existing exception handlers
needed some wrapping for pt_regs access, acessing the registers
via a RELOC_HIDE() pointer.
The strcpy() issues popped up here too, so add -ffreestanding and
kill off the symbol export.

Previously big endian was simply assumed if little endian was
not set, which led to some cflags ordering issues. There's not
much point to not having a big endian option, so shove one in
a choice and wire it up in the Makefile.
This lets us clean up some of the cflags ordering while we're
at it.

This adds some preliminary support for the SH-X2 MMU, used by
newer SH-4A parts (particularly SH7785).
This MMU implements a 'compat' mode with SH-X MMUs and an
'extended' mode for SH-X2 extended features. Extended features
include additional page sizes (8kB, 4MB, 64MB), as well as the
addition of page execute permissions.
The extended mode attributes are placed in a second data array,
which requires us to switch to 64-bit PTEs when in X2 mode.
With the addition of the exec perms, we also overhaul the mmap
prots somewhat, now that it's possible to handle them more
intelligently.

This drops the various IRQ headers that were floating around
and primarily providing hardcoded IRQ definitions for the
various CPU subtypes. This quickly got to be an unmaintainable
mess, made even more evident by the subtle breakage introduced
by the SH-2 and SH-2A changes.
Now that subtypes are able to register IRQ maps directly, just
rip all of the headers out.

The ipw2200 BSS firmware passes on the TSF information within ipw_rx_frame,
but monitor firmware doesn't. I add back the IEEE80211_RADIOTAP_TSFT flags
so that we can get the MAC timestamp if we use the rtap interface. We will
see the MAC timestamp equals to zero if we capture the packets with a
monitor mode interface. But this is the expected behaviour.

megaraid's MMIO RD*/WR* macros directly call readl() and writel() with
an 'unsigned long' argument. This throws a warning, but is otherwise OK
because the 'unsigned long' is really the result of ioremap(). This
setup is also OK because the variable can hold an ioremap cookie /or/ a
PCI I/O port (PIO).
However, to fix the warning thrown when readl() and writel() are passed
an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding
the same value as 'base'. This will silence the warnings, and also
cause an oops whenever these MMIO-only functions are ever accidentally
passed an I/O address.
